Introduced for the 2013 model year, the Cadillac XTS is a modern interpretation of the old Cadillac DeVille/DTS. To that end, it’s a full-size front wheel drive luxury car that’s loaded with features, and looks like nothing else on the road. Gone is the venerable Northstar V8, but its 3.6L V6 makes just as much power. The twin turbos on the Cadillac XTS V-Sport model push power well past the 400-hp mark. These engines are a paired with either the 6T70 or 6T75E, which were mostly reliable. However, Cadillac XTS transmission problems do still occur. So let’s find out what you can do about them.

Cadillac XTS Transmission Recalls
Cadillac XTS Technical Service Bulletins (TSB)
TSB 13120A – 2013 Cadillac XTS
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.

Can I drive with a transmission problem?
For the most part, Cadillac XTS transmission problems may or may not sideline the car. It all depends on the severity of the issue. However, continuing to drive the car when there’s something wrong with the transmission, can often create a more expensive problem.
How often does a Cadillac XTS transmission need to be replaced?
Proper maintenance is the easiest way to extend the life of a transmission. However, factory design flaws can lead to common failure points, which can obviously reduce the service life. On average, a Cadillac XTS transmission will usually last between 130,000–180,000 miles. A remanufactured transmission on the other hand, can last for considerably longer.
How are Cadillac XTS transmission issues diagnosed?
In order to figure out what’s causing your Cadillac XTS transmission problems, a mechanic will need to connect a scan tool, so they can retrieve all of the diagnostic trouble codes that are stored on the car’s computer. After that, a visual inspection and possibly a test drive will be needed to verify the source of the problem.
How is a Cadillac XTS transmission replaced?
Based on the GM Epsilon II platform, the Cadillac XTS is primarily a big FWD sedan. As such, the front subframe may have to be partially removed to gain access to the transmission. After installing the new transmission, the ECU / PCM will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Cadillac XTS Transmission Problems
Solution A: Buy a Used Cadillac XTS Transmission
In order to save money and get back on the road fast, you might be tempted to go buy a used 6T70E / used 6T75E transmission from a junkyard. And sure, you will save a little bit of money. But that savings may be short lived, because there could be even bigger problems hiding in that used gearbox.
Solution B: Buy a Rebuilt Cadillac XTS Transmission
Perhaps a more sound solution would be to purchase a rebuilt 6T70E / rebuilt 6T75E transmission. These have a lot of new Cadillac XTS transmission parts in them, and most come with a 1-2 year warranty. However, if the transmission is simply returned to a factory state, then all of the original failure points will just fail again. And that warranty may only be good at the shop that built it, which would essentially leave you without coverage if you travel.
Solution C: Buy a Remanufactured Cadillac XTS Transmission
If you want to get the most miles out of your Cadillac XTS, you need to consider getting a remanufactured 6T70E / remanufactured 6T75E from a reputable supplier. Unlike a rebuilt transmission, a good remanufactured transmission will be modified to correct for the factory design flaws. This will make it last a lot longer than the stock transmission did. Plus, some reman transmissions are covered by a nationwide warranty, which will protect you from transmission repair bills, no matter where you drive.
