Motor mounts

Post by Jayblk16 »

Hey guys new to the gang, I have a Bonne 2001 ssei always had a motor mount issue mainly the front mount...after changing it multiple times I decided to change all of them.coming to the last rear mount I notice a major problem, the mount that's connecting to the transmission bolts are broken off inside the transmission housing, which is causing a terrible shift and keeps blowing the front motor mount as well.I was wondering if anyone has a clue about removing them.I tried a couple shop I keep getting the run around, gm told me over 1000 just to take the trans out and inspect it so not taking that route any help would be great

You should be able to (will have to) remove the broken ends out of the tranny in order to replace rear mount. Will have to be drilled out and that will be no fun. You can try bolt removal bits. You drill a hole down the center of the broken bolt and use these removal bits to try to spin them out. Maybe they broke in removal attempt wanting to replace rear mount. Never personally heard of both rear bolts breaking on their own but an impact tool without penetrating fluid might do this. Good luck!

Hopefully you can get the broken bolts out with the methods outlined above.

After you manage to fix that problem, replace the mounts. The front one should be replaced with a solid type mount, either boat roller or hockey puck, and you'll never have issues again.
