Q: A 2014 BYD Su Rui, 1.5T, automatic transmission, shakes when starting, and there is a feeling of being out of gear, especially when the first and second gears shake more obviously. What is going on?
A: In theory, an automatic transmission car should be very smooth when starting. If the vehicle shakes when starting, one should consider whether the engine has leakage. If the engine has leakage, there will be a fault phenomenon of vehicle shaking. If the vehicle shaking is not caused by the engine, it may also be caused by the transmission. In this case, when the vehicle starts, the engine sound feels normal, and the shaking is caused by the uneven clutch when engaging.
