motor mounts or tranny mounts
 

How many mounts are there? I have replaced the two in the front, one on the passenger side and the one in the front down by the transmission. Is there another one or is there also a separate tranny mount. I am getting a "thump" sometimes when my tranny shifts and I am wondering could it be mount related.

i have been experiencing the same thing. topping off my trans fluid helped some. have you checked yours recently?

yes, tranny fluid is topped off and clean. Tranny rebuilt about 2 years ago. Also just had oil change and they also checked tranny fluid.

Mounts are:

1 at the front of trans (driver side)
1 at the passenger side
1 at the rear of trans (driver side)
1 dog bone rear of trans (pass side)

are the motor mounts the same for all bonnevilles, or different in yours since it is an SSEi? mine is an SE, and i am trying to get the motor out.....

All the mounts are in the same places.

You are trying to get the motor out? If the trans is staying in.. then remove the mount by the water pump, unbolt the trans and you are out. Remember about the one bolt in the trans to engine that is backwards and only accessible through the passenger wheel well with long extensions.

If you are pulling the engine with the trans:

No I am not pulling the engine. I have a "thump" sometimes when my tranny changes gears and I think it may be mount related.

no, it was me pulling the engine, and i finally got it all out, and it was annoying, i found a new bolt holding the engine to the tranny every day, but i know i got them all now.
