I purchased this vehicle is certified preowned Cadillac and during the warranty time I had a transmission issue that was causing the transmission to jerk when shifting from 1st to 2nd gear and at highway speeds, it would start jerking nonstop. I took it to the dealer and as per a service bulletin, they flushed the transmission fluid and replaced the transmission fluid.

smell the transmission clutches burning and the transmission overheating, possibly causing the number four piston rings to come apart, resulting in an engine replacement as well. I've had to replace engine as possible result, but the transmission problem is still there and it has also caused the check engine light to come on intermediately. This could result in a complete transmission failure, causing a vehicle to lose propulsion leading to a possible accident and injuries. This issue needs to be investigated and repairs or replacement made at the manufacturers expense.. This is a four-cylinder turbo engine and an eight speed automatic transmission. In my opinion, the transmission issue caused my engine failure. There should be investigated and an immediate recall issued.
