GM (not just Cadillac) has a problem with its 8 speed transmissions up through 2018. Sometimes a flush with Mobil 1 (blue label) can take care of it. If not, then a replacement torque converter fixes the “shudder” problems. A spendy fix unless your powertrain warranty is still in effect. With its new torque converter our 2018 now runs like new again; with crisp handling, good response from the 3.6 liter engine and a very comfortable ride.

This is my 5th Caddy and it doesn't disappoint. The transmission is the vehicle's only flaw. Hard shifts ruin an otherwise perfect experience. Working with a dealer to repair this concern but based on the other reviews, I have little confidence.

Hey guys, my first review ever but i had 2 share. I bought a 2017 cadillac ct6 used 34k on the dash. Drove it problem free for about 3 months. Then the noises started happening. Had 2 take it 4 times for them to finally fix some cover rattling on the catalytic converter. They said they welded it vs repairing it. Fixed that finally. Then the fuel injectors out. That left me stranded. The last straw was when thr car would jerk forward while in traffic. Traded it for the Mercedes S550. So far the best decision ive made as far as cars go. Loved Cadillacs had a Dts prior. Thanks for listening.

Get it in writing the price you're willing to purchase, because if it's too, good to true, then it probabily is.
