Can I drive with a transmission problem?
If your Toyota Tundra can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a Toyota Tundra transmission need to be replaced?
The overall lifespan of a Toyota Tundra transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Toyota Tundra transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Toyota Tundra transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Toyota Tundra transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Toyota Tundra transmission replaced?
In order to replace your Toyota Tundra transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed.

To save time and get back on the road faster, have your 17-digit truck VIN# handy and you can get an online quote for a reman Toyota Tundra transmission here, then find a local shop using our Find a Shop guide to install it for you.
How to Solve Toyota Tundra Transmission Problems
Solution A: Buy a Used Toyota Tundra Transmission
The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Toyota Tundra Transmission
Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Toyota Tundra Transmission
Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

I have the same problem with my 2012 toyota tundra
Please let me know if u find the problem mine is doing the same thing
I have been told by 1 that my transmission needed to be replaced, around $3000.. The second person told me the codes indicated it was “stuck” in some manner (?) , they cleared the codes said I was good to go (2 cases of beer). Drove almost a week before it coded again. Pulled battery cables, reset codes, anther week before code.. At this point I am fairly sure it has to be a sensor going bad or something with communication.. Plan to drive it till it won’t go anymore !!!
Had same warning lights…today transmission was failing. Transmission valve body failure. Common in Toyota trucks with certain transmissions. Repair estimate any where from $2200 to $4000.
Shifts weird from 1st to 2nd 2008 tundra limited
I had my 07 tundra transmission replaced with a used transmission with sixty thousand miles on it! It will not operate the speedometer properly! Can’t find the problem! Replaced module and speed sensor but still not working! I’m totally frustrated, is it time for dealership diagnostic?
07 tundra, 4WD. Sometimes when I go from park to reverse the truck acts like it’s in neutral. Is there a safety feature. I’m not familiar with the truck. It doesn’t happen all the time so is it something I’m doing when I shift.
Help 2000 tundra transmission took a crap

Tranny slipping while shifting uphill or under load
How do I add trannie fluid to 2010 tundra without taking it to the shop.
My 2006 tundra 4×4 is not working in reverse it had been slipping and now want do anything in reverse all the forward gears work someone said it could be a modgal bad any ideas or what options do I have Or to diagnose the problem
my 2007 tundra with 4.0 engine has 407,000 on it and i have not had any issues until now. in slow trade where i have to stop go or rolat varying speeds i get a shudder and sometimes a hard shift making me very cautious about how far i go from home. i have life time warranty on drive train. is torque converter considered drive train? i carried it to hendrix toryota in North Chas. and they serviced the transmission and it did improve the performance but not, conclusively. as long as i can accelerate at a fast rate the transmission changes smoothly with only and occassion shudder however if i slow down to go around a turn and it downshifts it shudderes as it tries to upshift. i have an appt to take it back wednesdy 1/15/2020. great truck. other than paint on roof of cab and hood it looks great too.
Have the rear end serviced- sounds like LSD May be chattering n causing what you are experiencing – with that many miles on it, if the rear end is not serviced regularly that could be the issue – probably the cheapest solution to try first n go from there
06 Tundra 4×4, 4 door, replaced carrier bearing, going forward with wheels turned slightly to the left driving off, I get a little like vibration or almost grinding feeling. I’m thinking now maybe rear transmission bearing that connects to the drive line, not sure
Won’t shift to 3rd gear
Mu 2007 was fine an then only reverse would work. Any suggestions. The factory trans was rebuilt T 75000 and at 123000 it only works in reverse. Help!!!!!
2002 Tundra, A340E, 330,000 miles, no issues ever, have done a full transmission flush ever 35k miles, want to start pulling a boat, < 2500 lbs, some long trips , 500 miles, maybe 3 times a year. Have been running full synthetic for the last 3 or 4 flushes, I realize my transmission may not be the norm, but is the A340E Transmission a reliable one on average? My Tundra came from the factory with a tran cooler. I will install a team gauge, where do recommend I put the sensor? Should I get a rebuild because of the miles, or wIt to see if any issues occur with high temp? Any observations or guidance would be appreciated? Thanks!
I have a 2014 tundra it shifts good until I drive it about 20 miles then it won’t shift from fourth then I can let it set for a while then it’s ok again what do I need to do

Since then the transmission has acted up Every now and then the trans slips when pulling away from a stop position . It is very intermittent .could go a day or a month before doing it again i have taken it back to the dealer several times They could not find a problem
All they told me was its under warranty if it go’s out we will take care of it I bought extra warranty when the factory warranty expired to cover the trans and running gear Thank god i did.. Since then the the rear wheel bearings.. front diff.. water pump has gone out [[[[ secondary air valves filled with water and was replaced under toyotas warranty]]]]

I have the 2007 with 80 thousand miles , with the exact same issues. They replaced the transmission because I have some platinum million mile warranty. That was 6 months ago. It’s back at the dealership now with the same issues. Only had 3 thousand miles on this transmission. They are replacing it again (still under warranty) but I know it’s not going to fix the issues. Now all my electrical things are acting wonky
2010 Toyota Tundra… Started shifting hard at 68,000 miles Im now right at 70,000 miles and its shaking/jerking in between gears. Unable to check transmission fluid on a dipstick under the hood. Warranty is up on vehicle… Any advice? Could it be low fluid level?
Trans locked in park
2007 Toyota tundra crew max as long as I let my truck run a good 30 min every thing is ok. But if i start it up and try to leave before then it either barely moves or do a lot of jerking until it warms up very frustrating. What if need to leave in a emergency not gonna happen has a 167000 miles on it
Same problem with mine
2002 tundra 120000 miles .Loud clunk accelerating into second gear,intermittently.Started Today.Four times.
same here
hi, i have a 2007 mod tundra 5.7 ltr with apr 200000 miles on it and gear no 6 doesn’t come in, test says solenoid prob. where to locate the solenoid , change it or …?
I have the same year truck with the same problem. I just had the dealer flush my transmission the other day and immediately afterwards it won’t shift smoothly between gears 2 and 3. Dealer said error relates to a solenoid and that I need a new transmission but I’m still in discussion with them on an alternate solution as it was functioning just fine until they flushed the tranny.
Don’t ever let them flush the tranny. Change fluid through the tranny cooler lines by pinning open the cooler thermostat. Flushing the tranny forces metal shavings and gunk into the little channels in the body causing your tranny to no longer work right.
My 2007 Tundra with 180,000 miles, is doing the same thing, about 3 weeks after having the tranny flushed(by a long time toyota mechanic)….Tranmisson guy says $1000 to $3400 to fix it. Should I trade it in or try to fix it.
Should try to fix it. these trucks are ment to last years., i just recently bought a 2011 Tundra with 170,000 miles on it and runs smoothly. But before that a 2004 Pontiac Grand am GT and had a torque Converter solenoid go out and had it rebuilt for 2500 with a 2 year 25,000 warranty and ran smoothly and good till i wrecked it. so yes do not flush it can cause issues from then on just go to a good transmission shop and get their opinion, but will say they cannot guarantee it because it is a transmission and may break.
