97 855 t5 Seized bolt for transmission mount

Post by GeekWarrior77 »

Changing out my lower engine mount and transmission mount due to clunky shifting. All went well until I hit a seized bolt on the transmission mount. It's one of the two bolted into the transmission housing. I'm guessing its the steel-to-aluminum phenomenon I've read about. I've started to damage the bolt so I'm taking it to my mechanic right down the street. When I put the new bolts in I assume I should use a some sort of preventative. Anti seize? Locktite blue? What do you think? Thanks.

Anti seize...as the lady says in the Frank's Red Hot commercial, "I put that $hit on everything!"

Thanks. That's what I used. Mechanic got the bolt. New mount in place. The clunk persists, unfortunately.

Have you changed the mount under the crankshaft pulley? It I have found is the worst offender for clunks from the mounts.
