Hello fellow Zedders! I hope someone her can assist with this issue.
I have a 2001 3.0i VIN LL33415.
When I accelerate quite hard to heavy I get this repeated bad vibration / banging sound which seems to be where the auto transmission is. I can't seem to pinpoint which gear it is in or be consistent rev readings. Anyway, it goes thud thud thud very rapidly for less than one second then goes away quite early in the acceleration. At first I thought I ran over a piece of wood and it was tumbling under the car.
I just replaced the tail shaft carrier bearing with no change. [today]
The rear subframe is in excellent condition.
The shocks seem to perfectly fine.
The wheels seem good.
The driver's side auto trans mount is a little bit squished [looks like it is leaning over a bit] but the mechanic said it is fine. There is almost no movement in the trans when pushed heavily on.
Engine mounts are good.
Diff mount and surrounding area is good.
the exhaust and mounting rubbers are like new.
there is no visual damage from any parts hitting anything that can be seen.
You can see, both me and the mechanic are at a loss. I am wondering if that slight deformation of the trans mount is the cause. Any suggestions people?
Can something be wrong within the trans?
