How to Solve the Transmission Shaking Issue in Cadillac ATS-L?
2 Answers
You can resolve the transmission shaking issue in the ATS-L by replacing the transmission and changing the transmission fluid. It is also advisable to clean the vehicle's throttle body and check if the spark plugs need replacement. Generally, there are four main causes: clutch failure, damaged transmission gears, deteriorated transmission fluid, or faults in the automatic transmission's hydraulic circuit or electronic control components.
I've encountered many Cadillac ATSL owners reporting transmission shudder issues, especially during acceleration when the car feels jerky. This is mostly related to GM's 8L45 transmission. The most common cases I've handled involve aged transmission fluid or unstable oil pressure. You should first check the fluid condition - if it's blackened or has a burnt smell, it needs replacement. I've heard many cars stopped shuddering after switching to new OEM transmission fluid - remember to use Dexron HD certified fluid. Another key factor is the torque converter; some production batches had factory defects, and I've seen cases where replacing the torque converter completely solved the shudder. If these don't work, you might need to check the solenoid valves or control module, since faulty electronic components can also disrupt shift logic.
