What Causes Shaking When Shifting Gears in an Automatic Transmission?
1 Answers
Automatic transmission shaking when shifting gears can be attributed to the following reasons: 1. The gearbox oil is too viscous and dense, causing the drivetrain to receive engine power more noticeably, resulting in a distinct vehicle shake. 2. It may be caused by a dirty throttle valve, excessive carbon buildup in the intake pipe leading to low idle speed, or misfiring in the ignition system (such as faulty spark plugs or ignition coils), as well as poor fuel quality. These issues are related to the engine's operating condition. Switching to N gear may improve the situation, but occasional engine shaking can still be felt. 3. It could be due to quickly shifting from D gear directly to P gear when parking and then turning off the engine. In this case, the transmission may not fully reset internally, causing shaking when shifting gears the next time the vehicle is started.
