The Cadillac SRX is a mid-size luxury SUV that was first introduced for the 2003 model year. Initially, it was rear wheel drive and offered the option of a Northstar V8 engine. But that all changed for the 2010 model year, when the SRX was redesigned on a FWD platform and became what we now know as a crossover/CUV. This transition more than doubled the sales volume, and made Cadillac an actual player in the luxury CUV segment. Throughout its life, a number of fairly reliable 5 and 6-speed transmissions have been offered. With proper maintenance, these gearboxes can last for a good long time. However, Cadillac SRX transmission problems do still happen. So let’s find out what you can do about them.

Cadillac SRX Transmission Recalls
2013 Cadillac SRX Recall – 13V097000
Summary – On certain models of the 2013 Cadillac SRX, the transmission may inadvertently shift into ‘Sport Mode’, reducing any engine braking effect.
Consequence – As a result of losing engine braking, the vehicle may not slow as expected, increasing the risk of a crash.
Remedy – To fix this problem, GM released a software update for the transmission control module/TCM, and will install it free of charge. Owners can contact Cadillac at 1-866-694-6546. Or they can call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236

2013 Buick LaCrosse – 2013 Cadillac SRX
Summary –
On certain models of the 2013 Buick LaCrosse and 2013 Cadillac SRX, the transmission may inadvertently shift into ‘Sport Mode’, reducing any engine braking effect.
Consequence –
As a result of losing engine braking, the vehicle may not slow as expected, increasing the risk of a crash.
Remedy –
To fix this problem, GM released a software update for the transmission control module/TCM, and will install it free of charge. Owners can contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236
Cadillac SRX Technical Service Bulletins (TSB)
TSB 07-07-30-032B – Ignition key sticks, shifter binds, “shift to park” message displayed, dead battery – 5L40 Transmission | 5L50 Transmission | 6L50 Transmission | 6L80 Transmission
2007 – 2008 Cadillac SRX – 2007 – 2008 Cadillac STS – 2007 – 2008 Cadillac STS-V – 2008 Cadillac CTS
Problem – Owners may notice that the shifter seems to bind when shifting into gear or park. The ignition key may stick or be difficult to remove (SRX only). A “shift to park” message may be constantly displayed in the driver information display screen, resulting in a dead battery.
Solution – These transmission problems may be caused by out of adjustment shift linkage, a slow Brake Transmission Shift Interlock mechanism, or a Park Confirmation microswitch that is not closed.
TSB 02-07-30-026 – Transmission shudder during hard acceleration – Cadillac SRX 5L40E / 5L50
Problem – During hard acceleration, it is not uncommon for the transmission to shudder/shake after launch. This is caused by insufficient clearance between the driveshaft attaching bolts and the transmission output shaft flange.
Solution – Install a revised transmission output shaft flange.
TSB 13120A – 2013 Cadillac SRX 6T70E
Problem – The torque converter clutch solenoid can stick due to debris in the transmission. When the vehicle is at the end of a coast-down, as the vehicle is coming to a stop, a stuck solenoid will fail to release the torque converter clutch. This keeps the engine directly connected to the driven wheels. As the vehicle stops, the engine speed will be pulled down below normal idle speed and the engine may stall. The vehicle can be immediately restarted and driven.
Solution – The valve control solenoid should be replaced, and the transmission control module will have to be reprogrammed in order to correct the problem.
TSB PI4075 – 6T75 transmission overheating
2010 – 2012 Cadillac SRX
Problem – The 6T75 transmission could experience an overtemperature situation, even if it’s not warranted by the driving conditions. This issue will be accompanied by a warning message in the drivers information center (if so equipped) and one or both of the following DTC’s: P0218 and/or P0634.
Solution – If a mechanical issue is not determined to be at fault, then it’s possible that the problem is caused by too much transmission fluid, dirty transmission fluid or restrictions in the transmission cooler circuit. Click the above link to learn more about this TSB.
Common Problems with the Cadillac SRX Transmission
Input/Output Speed Sensor Issues – Cadillac SRX 6T50
Problem – When repairing a failed input speed sensor or output speed sensor, steering system damage could occur.

Can I drive with a transmission problem?
In many cases, the average Cadillac SRX transmission problems won’t hamper drivability. However, you do run the risk of making the problem worse. Which can, at the end of the day, cost you a lot more money.
How often does a Cadillac SRX transmission need to be replaced?
Regularly scheduled maintenance is very important to extending the life of your Cadillac SRX transmission. But even with proper maintenance, OE design flaws can still cut the service life short. On average, we’ve noticed SRX transmissions tend to last between 130,000-180,000 miles. But a well designed remanufactured Cadillac SRX transmission can last significantly longer, if all of the factory design flaws have been addressed.
How are Cadillac SRX transmission issues diagnosed?
In order to determine what is causing your Cadillac SRX transmission problems, a technician will need to connect a code reader to the OBDII port under the dash. Once all of the diagnostic trouble codes have been read, a visual inspection can be performed to verify the source of the problem.
How is a Cadillac SRX transmission replaced?
On the first generation (RWD) Cadillac SRX, the exhaust system and driveshaft will have to be removed before lowering the transmission from the chassis. Installation is a reverse of the removal process. On FWD models made after 2010, the subframe may have to be partially removed before the transmission can be removed from the chassis. But in either case, the ECU/PCM will have to be reprogrammed / reflashed to accept the new transmission.
Recommendations for Cadillac SRX transmission issues?
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 Cadillac SRX transmission here, then find a local shop using our Find a Shop guide to install it for you.
How to Solve Cadillac SRX Transmission Problems
Solution A: Buy a Used Cadillac SRX Transmission
To get back on the road as quickly responsible, a used 5L40E / used 6L50 / used 6T70E transmission from the local junkyard might seem like a viable option. However, you don’t know how it was maintained. So you might wind up having even more Cadillac SRX transmission problems down the road. Plus, that junkyard warranty probably does not cover labor charges.
Solution B: Buy a Rebuilt Cadillac SRX Transmission
Another solution would be to get a rebuilt 5L40E / rebuilt 6L50 / rebuilt 6T70E transmission. In this scenario, a mechanic will take your existing gearbox and install a bunch of OE spec Cadillac SRX transmission parts. Most of the time, they will also give you a 1-2 year warranty. However, that warranty may only be honored by a single shop, which means you will have to pay for transmission repairs out of pocket if you travel. And those factory spec transmission parts mean that any premature failures due to a design flaw will return.
Solution C: Buy a Remanufactured Cadillac SRX Transmission
To achieve a more permanent solution to all your Cadillac SRX transmission problems, you might consider a remanufactured 5L40E / remanufactured 6L50 / remanufactured 6T70E transmission. If they are done properly, a reman transmission will be upgraded to address all of the factory design flaws. This will provide you with a longer service life and much better performance. Plus you may even be able to get a nationwide warranty, so you don’t have to worry about breakdowns when you travel.
What Transmission Do I Have?
What Problem Does Your Cadillac SRX Have?
Let us know the year, mileage and problem you’re having as well as any trouble (OBD) codes you’ve found. If you’ve been given a quote or paid for a repair, we’d like to hear about that too!
Acts like it is neutral and then will go on
08 srx started not shifting into gear,so after fluid and filter change and Lucas tranny repair ,worked for a month then stopped.let sit for 2month put new battery in and it worked for 50miles and stopped.if I unhook battery and touch cables together it will go and shift into 2and 3rd then will just Rev up after that. So if I do it again touch the battery cables together it’ll again go about a half a mile before it won’t shift anymore and it’ll keep doing that. So don’t know if I got solenoid problems or P cm is to be reprogrammed or what is going on driving me nuts
Code 0797 pressure control solenoid
Car would feel like it was pulling and rpm would go crazy, did a transmission flush 2 days before check engine light came on.
I have a 2015 Cadillac SRX and started up the vehicle drove 4 blocks and it wouldn’t shift into park. The handle comes to a halt right after getting past the R before the Park symbol. I shifted it to neutral and it started up and I drove it home. Now I can’t get the shifter out of drive. From under the hood, I grabbed the shifter cable lever and noticed the cable moves a bit when the shifter inside won’t move. Like a linkage issue. The SRX has run fine up until this. I disconnected the battery in an attempt to keep it from being drained. Too late, went to start it up and because I can’t get it out of drive it won’t start, (of course), problem now is ive got it parked in my 1 car garage and I’m retired and need to know what I could expect the cost to replace the cable might run. My wife and I both rely on it. It’s our only transportation at home. If I could get an idea of a cost from a professional opinion I would appreciate. If I could get the shifter to release it from Drive I might get it into neutral and be able to drive it to a shop. 2 weeks ago I sold our second car, (2002 Camry w/265k miles) original owner.
I’m bummed to say the least.
Neutral safety switch
My SRX is not changing gears and making a roaring noise
I’m having the same prob. Did you have yours fixed and what was the problem? Please I’m going nuts and broke trying to find out what’s wrong
After warming up the transmission in speeds 10 to 25 mph jumps or bumps hard when you let off the gas in slow traffic or just going slow
My car is the same year and model; and having the same issue. Did you find out the cause and solution for this issue?
2015 Cadi SRX Lux speeds 10-25 MPH jumps or kicks hard when you let off the gas pedal only in slow traffic or sitting bumper to bumper traffic.
A knocking noise directly related to speed. starting at lower speeds undet acceration and going away at about 40 mph.

2004 srx 3.6 goes in to limp mode warning “reduced engine ” power, unable to accelerate, won’t pull a hill, won’t exceed about 20mi per hour, will sometimes starting idling up and down on it’s on..traction control will kick off and check engine light comes on and stays on..throttle position sensors replaced at least 3 times and wiring harness/connection cable from ECU to throttle body has latest configuration as of 4-2015..not sure if related but head lights, markers and signal bulbs have been replace frequently on the drivers side and also passenger side, the functions of the information center no longer works properly, drivers side heated seat no longer heats, sideview mirror (passenger side) no longer returns to memory position after backing up and going forward (drive)….reduced power happens without any warning…very very dangerous…
Uncontrollable idle could be gas pedal position sensor. It talks to the computer and the throttle position sensor. Need to read your codes turn off traction control and limp mode should disengage turn off back up mirror position live with looking passenger heat seat check wiring under seat for current when on bulbs blowing just bad luck or alternator is over 14.7 volts maximum
Well my 2006 Cadillac SRX 3.6/L. Transmission will not shift properly. RPMS are up at 3000 coming out of 1st gear and goes from there along with no power to get up a hill. I have replaced the transmission control module. And it worked fine for a half if a day. Help!!!!
2008 Cadillac SRX. Does not shift into high gear when on freeway. 60 MPH runs about 2000 RPM.
key won’t start the car
I have a 2015 Cadillac SRX with 47,000 miles and in the last two months, its has started this jerking thing and I feel it under the front seat. I have had it to the dealer two times and both times they said it is normal, that there is nothing wrong. They also said it could be my driving. But, they can not explain to me why all of a sudden it just started happening. Your thoughts please.
Happens to me too. However, now I am having issues with the gears. I am taking it in this week to be serviced.
Take to another dealer. I was having the same issues on my 2015 srx. The dealer kept saying that was normal. Last week I found out it was not normal and now I am getting a new transmission installed. All covered under the warranty.
2010 Cadillac SRX AWD transmission light comes on and off and gage reads low pressure and drops into safety mode want change up in gears. I’ll stop engine for a while then restart issue goes away. I think it is sensor related. Your opinions will be appreciated
