Nuisance problem with my 2005 Ford Explorer 4.6 V8 and 5R55S transmission. Shifts occur at uncommonly high RPM. 2000 to 2300 Rpm under moderate, normal acceleration. Difficult to ease it along to get a shift at 1500 rpm.
Another problem is an exceptionally touchy and erratic throttle response (especially bad after initial engine start and transmission engagement) The car has prox 85000 miles. Concurrently owned a 2002 Exporer Ltd with same engine and trans with 185000 miles and no similar problem
Any ideas on potential causes of the problem and how to diagnose and repair or reprogram?
Need a replacement transmission? Quality transmissions are hard to find. Free estimate to your email.April 30, 2015 at 2:26 am in reply to: Junkyard Transmission Replacement Risks, Cost & Worth it? #948Administrator5KeymasterReply submitted by Tanya:
My husband has a 1996 Chevrolet extended cab the transmission tore up last year bought one from junk yard no good then bought a brand new rebuilt transmission from Autozone it still slips in 2 gears – 3rd and overdrive since my husband put in the transmission the warranty is no good your suppose to let a professional check it out to make sure it’s working good but since my husband put it in the warranty is no good. $1300 down the drain it’s been sitting for a year is there any place cheap that will fix the transmission around Cleveland tn?
Administrator5KeymasterFor a manual transmission, this problem is most likely related to a worn (out) clutch. Try putting the car in a higher gear, like 3rd, then slowly release the clutch. If the clutch is working, the engine will stall. If the engine is still running after you release the clutch, then you’ve found the problem.
For the automatic transmission, the most likely culprit is the valve body. This complex part uses a series of chambers, valves, and springs to direct the flow of pressurized transmission fluid which engages the gears. If the transmission goes into gear, but the vehicle won’t move, there’s probably not enough hydraulic pressure in the valve body to engage the forward gears.
Administrator5KeymasterNo matter how brave you are, it’s not safe to be driving a car with this problem.
From what you described, it sounds like there’s an issue with the shift linkage, and/or the bushings. When move the shifter to the desired gear, a cable connected to the shifter moves a lever on the transmission, putting it into the desired gear. If the cable / shift linkage, or bushings are worn, you won’t be able to easily select gears. And it may come out of gear unexpectedly, like it does when you come to a stop. This is a relatively inexpensive problem to fix, and you should do so, before it slips out of gear and causes you to have a wreck.
Administrator5KeymasterYour Mitsu service guy is right. Resetting the Engine Control Unit / Transmission Control Unit probably won’t solve the problem. It sounds like you’ve got worn clutches inside the transmission. If the fluid was translucent pink before you had it changed, the previous owner likely had it serviced in an effort to fix the same problem.
One thing though, Mitsubishi automatics require a unique automatic translation fluid called Diamond SPIII, or an equivalent synthetic. If a lesser fluid is ever used, internal damage can occur because the chemical makeup of the non-approved fluid won’t be able to properly protect the moving parts from heat-related damage.
Administrator5KeymasterThe Honda Odyssey is known for transmission problems, so having a new transmission recently installed is actually a good thing. Just be sure to service the transmission every 30,000-40,000 miles, as this will extend the service life of the new transmission.
Besides the transmission, the Honda Odyssey is quite reliable. The V6 engine is good for 200,000-300,000 miles (if you take care of it), so getting a new transmission with only 130,000 miles on the clock means you could be driving it for a long time.
Administrator5KeymasterFront main seal failure is usually caused by something else, like a front pump issue, or a bad bushing / bearing. Since you ran it without fluid, the extreme heat that would’ve built up inside the transmission, likely damaged the clutches, causing the slow gear engagement that you mentioned. So just replacing the front seal probably won’t fix that transmission. The most logical solution (given the age of the car) would be to put a used transmission in it, then drive it until it dies. If you continue to drive it as-is, you’ll eventually be walking home.
Administrator5KeymasterFirst of all, check your transmission fluid. If it appears brown, or has a burnt smell to it, then the transmission filter could be clogged. This can fixed by changing the transmission fluid and filter ($50-$75 DIY / $200-$300 at a repair shop).
Next, assuming the Check Engine Light was triggered, pull the error codes with a scan tool. If a transmission code was registered, it should tell you what the problem is.
Worst case scenario, the clutch pack has gone bad, and you’ll have to rebuild it.
Administrator5KeymasterUnfortunately, the 6T70/75 transmission used in the 2007-2009 GMC Acadia, 2007-2009 Buick Enclave, 2007-2009 Saturn Outlook, and 2007-2009 Chevrolet Traverse is prone to early failure, due to a design flaw (specifically, a weak 3-5-Reverse wave plate). GM redesigned some of the internal components, and started installing the revised 6T70/75 transmission during the 2009 model year. A new GM tranny from the dealer usually costs $3,000-$4,000. But the revised transmission should keep you rolling for a good long time (until something else breaks:-)
April 1, 2015 at 12:46 am in reply to: 2002 Hyundai Santa Fe Transmission Failed Without Warning #663Administrator5KeymasterSounds like your 4WD transfer case failed, which can cause severe damage to the input splines inside the transmission. It’s possible that the gear oil inside the transfer case (about a pint) leaked out, causing it to suddenly seize up. If this happened, it is entirely possible that the transmission was damaged as well.
The labor time to replace the transmission is listed at 15 hours, and replacing the transfer case should take about 9 hours. A used transmission with 50k miles should run between $750-$1,000. The transfer case typically runs $500-$600. If the quote of $2,500 includes the transfer case (provided that was the problem), and labor, then it seems about right (a little high, but not unreasonable).
Hope that helps!Administrator5KeymasterOk, a sturdier dual-disc clutch, like those from Haisley and South Bend, typically cost between $1,200-$1,900. This will help you hold all that extra power. But in order for this upgrade to work, you’ll also want to switch over to a stronger 1 3/8″ input shaft. A built NV4500 with these upgrades, and a reinforced 5th gear can run you $2,500-$3,000 (plus core). ATS sells them, Part # 3119542212. Or, if you know of a good transmission shop, they might be able to build you an NV4500 for a little less money. And, you’ll be able to pick the specific components that they use.
January 29, 2015 at 1:32 am in reply to: Junkyard Transmission Replacement Risks, Cost & Worth it? #545Administrator5KeymasterI’m glad to hear you found the article helpful!
What sort of problems are you experiencing with your car? Trouble shifting? Noises? Warning lights on the dash? I would suggest doing your best to diagnose the issue by searching Google and maybe even paying for an hour or two of a mechanic’s time in order to get the diagnostic codes from your car’s computer and determine what the cause is. That said, I assume you know that your tranny is on its last legs since you’ve been adding Lucas to it.
Buying a used transmission from a junkyard is definitely one of the cheapest ways to get a replacement transmission and as you said, since the model was so popular and given its age, there should be a good number of them lying around. You’re right that it might be risky (it might fail not long after you have it replaced), but if you can find one that has been tested by the salvage yard and is in decent condition with low mileage, then it’ll keep your car on the road a lot longer than a few infusions of fluid ever could. I would also try to avoid one that has been in an accident (if possible).
A possible difficulty with this approach is finding a mechanic who is willing to install a transmission that they don’t provide. A local independent mechanic is probably your best bet as most dealerships and chains won’t use parts provided by their customers (for both liability and profit reasons).
If finding a transmission or a willing mechanic proves too difficult, your next best option would be to ask your mechanic to find and install a used or rebuilt transmission. This will possibly cost a bit more due to markup (“finders fee”) and/or the transmission having some kind of mileage/quality guarantee or warranty.
Quick comparison of cost and reliability:
Junkyard – $800-$1500. most scrap yards give a 90 day to 1 year warranty, but most people only expect it to last a year at best and are planning on unloading the car soon or done have the money to pay for a regular rebuild.Rebuilt – $1500-$2500. last another 2 to 3 years or so. Usually has 1-2 year warranty.
New (Remanufactured) – $1300-$3200+ 3 year warranty
Hope this helps!

Administrator5KeymasterFirst of all, I hope that no permanent damage was done to the transmission when you started to hear the grating/grinding noises due to the low fluid levels.
I’m not really sure what “one of the drivers” meant by the line being overfilled. The cheapest option would to be try Trans-X to see if it is able to stop the leak and reduce/prevent slipping. Be sure to check your fluid levels and under your car very frequently for the first few days after using the additive to make sure you’re no longer losing fluid. If that doesn’t work, take your car to your mechanic and have them do a thorough inspection of the source/cause of the leak and to replace/patch the lines if they are what is causing the problem. Once you’ve had success with one of these approaches, get your filter and fluid changed and then add some more Trans-X.
It is important to note that this is not a permanent solution and you should probably change your transmission fluid and add more Trans-X every 6 months to a year now since your car is old and high-mileage.
Administrator5KeymasterOkay. Well I did happen to replace the clutch master cylinder. Did all the work myself. Bled all the brake lines and from the slave cylinder. Got all the air bubbles out and to the point that new fluid was coming out strongly. Got the clutch pedal all firm and the brake pedal the same way. But turned out it was the clutch. It’ll start and everything. The linkage and everything is fine. But it must be the clutch. But it was worth a shot for sure. I appreciate your help. It was a lot cheaper then the clutch. Was worth a shot. But turned out it wasn’t that. But thanks again for your help and your time man.
Administrator5KeymasterFrom what you’ve described and without seeing the vehicle, I’d say the guy is on the right track. I would give bleeding the clutch master cylinder a try as an air bubble is definitely a possibility. It’s not guaranteed to be solution, but it’s a likely fix and a heck of a lot cheaper than having to replace or rebuild the entire transmission.
Administrator5KeymasterWell today I just had the guy who sold it to me. To come out and check it out. He said it could be and looks like its just the clutch master cylinder. And there is brake fluid liquid leaking into my car from it. So as he said it could just be that. Since the clutch pedal itself is really soft or even spongy. As we did a week ago replace the brake lines. Only bled the front two because those were the ones needing replaced and bled again. Thought the back ones would be fine. But we also left the cap on the reservoir.
As the guy told me today we needed to bleed all four and possible the clutch master cylinder to get it to work again. I mean all the linkage and bushing and it was going into every gear but maybe it just wasn’t engaging/ disengaging since the clutch pedal itself was bad and everything else was fine to him. But as he said there must of been an air bubble somewhere and it must have gotten into the clutch master cylinder, as I pushed/ stepped on the clutch pedal in which wouldn’t let me shift or engage/ or disengage the gears letting me move/ or go.
So in which I mean everything else seems fine. But I mean what is your opinion on the matter? Could it just be the clutch master cylinder? Since it is leaking into my car and the clutch pedal itself is really soft or loose and being able to push it all the way to the floor?
Maybe this will help a little more and give you a little more info.
Thanks for your time man. I really need this fix. And i don’t want to have to go out and buy something if i don’t need it or it doesn’t need to be replaced yet. Or spend money out my already dry pockets. You know?I hope this helps maybe diagnose it a little better and gives you a little more information to work with.
Administrator5KeymasterBased on your description it is not clear to me whether or not you’re able to change gears (even though the car won’t go anywhere). Since you were experiencing high RPMs before and your car won’t budge now, it’s definitely a problem inside your transmission. My guess is that you will most likely have to get the clutch replaced because it won’t engage/disengage (letting you “shift” the stick but the car won’t movie which means it’s probably completely disengaged/worn out).
You’ll have to take your car into a transmission shop or mechanic that works on transmissions in order to have the repairs done. A really rough estimate would be around $1000 to give you an idea of how much it will cost.
Hope this helps! Good luck.
Administrator5KeymasterA transmission rebuild (or any car repair for that matter) should never fail after only 20 miles of driving! Based on the list of parts they recommended you have fixed (that you said no to), the spark plugs are the only one that would cause an engine to stop working. There is definitely a chance that they made a mistake. The problem most likely has something to do with the rebuilt transmission in which case, it is the mechanic’s responsibility to get your car running again.
The first thing I would do is go back and discuss the situation with them. Ask them to repair your car and get it back in working order. If the shop is honest and has a good reputation, then they should be willing and happy to take another look to see what the problem is and fix it.
Did the shop offer some sort of warranty or guarantee on their work? Most reputable shops do. A typical agreement will state how many miles they guarantee the rebuilt transmission will work properly. If the shop refuses to help you and only offering to buy your car for pennies, they could be trying to scam you by taking your money for the repairs, making sure your car failed shortly after and then offering to buy it for far below it’s value. In this case, I would contact the authorities such as the Federal Trade Commission (FTC) to report the scam.
If the first shop won’t help you, I would get a couple of other repair shops in your area to take a look at your car, tell you what’s wrong with it and give you a quote. You might be able to get the engine working again for the same or less than you paid the first time.
If worse comes to worst, then you can definitely get more for your car on a classifieds site like Craigslist or by contacting a company that buys junk/scrap cars.
Administrator5KeymasterI am posting this submission by Daniel here as it is similar to James’ inquiry.
I have a 2001 mercury cougar my car usually sputters or has trouble when going up hills and the transmission light came on today. I’m currently rooming with someone working a minimum wage job barely have enough to maintain a living hopefully whatever is wrong with my transmission is cheap and affordable to fix.
Administrator5KeymasterThanks for the update. Did the mechanic end up calling you back? Did you tell them that it’s slipping and that you’ve “started having problems with it”.
Are you low on fluid? If you are it could be due to a leak and is probably the cause of the slipping. Check the fluid level and top it up if it’s low.
There are two opinions on whether or not you should change the fluid on a high mileage (possibly neglected) vehicle:
1) Changing it will not cause the transmission to fail because it was going to anyway.
2) If you wait too long you should not change the fluid because it could cause the transmission to fail.
What is the mileage on your Odyssey and how long has it been since the last fluid change? What does the fluid look/smell like? If the fluid is very old or never been changed, burnt and contaminated, the damage might already be done to the transmission and you should just keep topping it up as it is only a matter of time before it fails. Changing the fluid won’t work miracles on an already damaged transmission (which yours probably is since the gears are slipping).
That said, there is an opposing opinion that says new fluid cannot harm a transmission/cause it to fail and that the “don’t change the fluid if it’s high mileage” is an old wives tale. If the tranny does fail after the change, it isn’t the fault of the new fluid, despite what the shops might say or what you read online. The transmission was going to die anyway as a result of the damage done due to long-term neglect. The shop and mechanic you have been talking to probably want to avoid this situation, as most people would blame them for “killing” their transmission.
Try asking them if they are speaking from personal experience (they’ve changed the fluid on a number of high mileage vehicles which have broken down shortly after) OR if they are simply reciting something they *believe* to be true. Ask them to back up their answer with good reasons.
If you do choose to have the fluid changed, make sure it is a CHANGE and not a high pressure FLUSH and that you get a new filter put in at the same time. A flush forces the old fluid out with pressure which could cause sludge and particles to get lodged in places they shouldn’t be and cause the transmission to fail or breakdown faster. As always, be sure to follow the recommendations found in your owner’s manual as the the type of fluid to use, etc.
Hope this helps, and keep me posted!
Administrator5KeymasterResponse from Gail:
A few days after I received your email I took my car into a francise transmission shop. I asked to have the transmission fluid changed. They told me that could make the problem worse. They drove the car and told me to continue to drive it until I started having problems with it. I then went to a local mechanic that has a good reputation. I talked with one of his employees and she agreed with the francise about the transmission fluid change and told me the mechanic didn’t have the time to look at it and said he would call me. He hasn’t called but I still would like to talk with him since he has such a good reputation. I have since felt the transmission slip a couple of times. It happens when it shifts from 1st to 2nd gear.
October 1, 2013 at 10:09 pm in reply to: Input Speed Sensor, P0212 codes and P0234, No 4th Gear #344Administrator5KeymasterHey galyagornishka, sorry to hear about your car problems.
The transmission’s Input Speed Sensor (ISS) is also know as a Turbine Speed Sensor (TSS) and is located on the outside of the transmission’s case. It determines the rotational speed of the input shaft or torque converter and relays this information to the control unit. Using information from the ISS and the vehicle speed sensor (VSS), the control unit can make adjustments to enable the vehicle to shift smoothly and efficiently. Symptoms include improper shifting, slipping and a lit check engine light.
So from the description you provided, the input speed sensor could definitely be the issue. The cost of labor and parts to replace the sensor should be in the $100-$200 range.
Code P0212 – Injector Circuit Malfunction. There is a problem with the fuel injector. It could be due to an open or shorted harness, a faulty injector or a poor electrical connection.
Symptoms – Engine runs rough/hesitation. Check engine light is on. Engine will be harder to start. Poor power/acceleration.
Solution – Fuel injector cleaner, check the wiring, check/replace the injector. Cost to replace: $70-$80 each plus labor
Code P0234 – Turbocharger/Supercharger ‘A’ Over boost condition. The Turbo Charging system uses a Boost Pressure Sensor sends info to the PCM so it can determine how much boost is being provided. When the sensor data reads above specifications or the Knock Sensors pick up pinging/knocking, P0234 is set.
Symptoms – Engine light on. Engine knocks or pings on acceleration or hesitates or stalls. Engine lacks power since there is no boost from the turbo charger.
Causes – Transmission oil temperature is too high, engine over temperature, knock sensor (KS) failure, faulty boost pressure sensor, faulty boost sensor wiring, ignition misfire exceeds threshold.
My advice is to take your Accent to a reputable transmission shop in the area ASAP. They will be able to provide a more exact diagnosis and give you an estimate for the repairs. Driving around before getting the sensor fixed will be very hard on your transmission and you could do enough damage to require a rebuild/replacement. If the problem is more severe than the sensor or codes and the transmission has to be rebuilt or replaced, expect the cost to increase significantly.
Administrator5KeymasterHey Amber,
Sorry to hear about the trouble you’re having with your Sorento. From the sounds of it, you’ve already found a good shop to go with since they charged you less than they quoted you for – a sign that they’ll likely stick to the estimate they give you for your transmission repairs. What are the names of the two shops you’re considering?
Check to make sure that your transmission isn’t leaking as a low fluid level could be the problem since you said that having the fluid changed fixed the shifting problems temporarily and then they reappeared after a short time. Also, was the filter replaced when you has the fluid changed?
You’re right that they cannot give an exact quote until they open up the transmission and look inside, but they should be able to give you an idea of how serious the problem is based on the symptoms they notice after taking your vehicle for a test drive. You say the problem is intermittent, so some minor repairs should do the trick. That said, since the vehicle is high mileage and has been running on old transmission fluid for a while, a major overhaul or replacement might be the more cost effective solution if one or more internal components are worn out/damaged.
It might be worth dropping the pan yourself and inspecting for excessive debris. If there is metal debris in the fluid, that could be jamming the solenoids. That would also be an indication of the failure of an internal component, meaning it’s overhaul or replacement time. If the bottom of the pan has minimal debris and the fluid is in good condition, you may just need a solenoid pack ($100-$200 plus installation).
Administrator5KeymasterFirst of all, I highly suggest you get the problem diagnosed by at least 2 other mechanics/service centers. This will give you options to compare and verify what the problem is. Dealerships are typically overpriced (you are paying for the brand name) and usually unnecessary for a 10+ year old car. Simply saying that “do not” open automatic transmissions should be a warning sign that they aren’t willing to do smaller, lower cost repairs.
If the problem is indeed just a bad bearing, then a full replacement isn’t necessary. The cost depends on the type of bearing causing the problem. If it is a differential bearing for example, you should be able to get the repairs done for around $1600 give or take a couple hundred. That said, if other problems are found within your transmission during the process, the final cost could inflate significantly.
Have you (or the dealership) tried changing the transmission fluid? Doing so could solve the problem or at least make driving easier on the transmission until you get it fixed.
Administrator5KeymasterHi Jenni,
I’m sorry to hear about your car troubles, you’re definitely in a tough situation especially since the car has only lasted a few months. Based on the age and how much you paid, a rebuild or replacement might not make financial sense and you might have to consider buying another used car to replace the GTI.
That said, you should be able to find an independent mechanic in your area who is willing to replace or rebuild the trans for half the amount they quoted you. Products and services provided by dealerships are always overpriced (you are paying for the brand) and definitely unnecessary for a 10+ year old car. And as always, I advise getting an estimate from more than one shop in your area and to get recommendations from family/friends so that you have information to based your final decision on.
Hope this helps!
