94 SSE Vibration at shift points
1994 Bonneville SSE non-supercharged 160K Automatic Trans
When the car shifts 1-2, 2-3 I feel a vibration similar to a wash board type vibration from a road surface. It only lasts about 1 second and then goes away.
I can’t say it does it all the time, mostly after a few miles of driving. The same is true for the type of acceleration. It is more pronounced on a hard acceleration but not always.
Anyone got any ideas…motor/transmission mounts….axles…..and god forbid the transmission.
