General Motors has issued a technical service bulletin (TSB) for certain examples of the 2020 and 2021 model-year Cadillac XT4 subcompact luxury crossover for a problem related to the clutch spring retaining ring in the nine-speed automatic transmission that comes standard in the vehicle.
The problem: in affected vehicles, the clutch spring retaining ring may not be fully seated. Vehicles with this problem will produce a warning light on the gauge cluster/instrument panel indicating a transmission malfunction, alerting the driver of the issue. This warning light will appear when the vehicle still shows low mileage on the odometer.
A TSB has also been issued for a similar problem in other GM crossovers equipped with the nine-speed automatic transmission, including the Chevrolet Trailblazer, Blazer and Equinox, Buick Encore GX and GMC Terrain.
The hazards: GM’s service bulletin for this issue does not indicate what problems an unseated transmission clutch spring retaining ring may lead to. However, as noted above, the problem will produce a malfunction indicator warning light on the gauge cluster/instrument panel. Additionally, this problem will produce a diagnostic trouble code (or DTC) of P0747.
The fix: Cadillac dealers will be instructed to inspect the transmission clutch spring retaining ring in affected vehicles. GM’s TSB indicates this particular service update “involves vehicles in dealer inventory only and will expire on February 28, 2022.”
Affected component: transmission clutch spring retaining ring.

Kind of on a different subject here, but I was able to drive and experience an XT4 first hand finally. This was not on purpose. My new CT4 A/C decided to quit on a very warm Sunday this past week. Took it in to the nearest dealer on Monday and they gave me a brand new XT4 as a loaner. It wasn’t bad, but I sure like the way my CT4 drives better. For whatever reason, the XT4 really feels more like a front drive car than what I expected. Maybe it’s because I’ve grown used to the RWD feel of my CT4? Don’t know, but I like the CT4 better and the screen layout in the XT4 is kind of strange. It needs to be angled more upright.
BTW, the service I received from the Cadillac dealer and advisor was fantastic.
I own a 2019 XT4 w/2,800 miles on it . Bought new. Rides like a lumber wagon. Rear shocks (if it has shocks) bounce over bumps and sound like they are shot. Dealer says it is the (oem) tires. Hueey! Certainly no luxury vehicle.
Weird. My 2019 XT4 rides beautifully. Passengers even comment on it. It rides much better than my 2013 ATS, even with new tires. Sorry yours isn’t the same.
My 2019 xt4 transmission is starting to slip 37000 miles
