My transmission is giving me.some.problems. Its a 6l90. Been leaking fluid out the rear at the yoke. Swapped the extension housing seal, still leaking still vibrating. I am assuming there is a bushing not.to far past the tailshaft that has gone out making the output shaft have a lil to much play, causing vibrations. Has anyone tore into this type of trans, or do you know what im talking about? If i am right, can you name that bushing. Gonna try to stay out the shop. If i just have to remove the tail shaft to fix the problem i feel i have the skill.

 

Well broke down and went to a trans shop. The bushing in the extension housing is shot. Not to expensive but the parts are hard to find. Went to the dealer to. Lets just say i will never buy another Chevy from a Chevy dealer. Kinda breaks my heart.

 

You cant get the part for an 07 ?

 

I think I have the same issue please let me know how hard to do. I also will do the job myself. New to forum today.
