Tranny Bushing Review

Correct, it is inserted from the front. I suspect that some of these aren't getting inserted all the way and the flange that sticks out then contacts the aluminum crossmember and transmits a LOT of vibrations then. When you insert it make sure it's completely home and it should ONLY touch rubber. If it touches the aluminum crossmember it will vibrate.

Yes, we still have some in stock.

Well if y'all still have some in a couple of weeks when i'm in town i'll stop by.

Installed mine from the front. I took the crossmember and trans mount out, then used lube and a vise to make sure the bushing was seated all the way. I verified it wasn't touching the crossmember before installing back in the car. I'm pretty particular about suspension and drivetrain parts being installed correctly.

I'm also a wuss, so it's been too cold for me to get back under it and see what's up. I might trim the whole center piece out like some have to see if that makes a difference. If it does, I'll report back. In the meantime, banging gears like a madman has been fun.

PS - I have some generic poly bushing "shifter bracket" in the car. Otherwise the drivetrain is 100% stock.

Figgered it out.

Took down the trans mount and it was immediately apparent that the lower/wider section of the WL bushing was protruding through far enough to make contact with the crossmember. It was obvious where it was rubbing.

So I grabbed a razor blade and trimmed off the part that protrudes through the trans mount, about 3/8", all the way across. Some people whack off that whole lower section of the bushing, but that seems drastic.

Took it for a spin and NVH-wise I can't even tell anything is different than stock, but high rpm shifts are precise as before. This is how it's supposed to feel.

Sweet! I'll have to trim mine once I get the time to Jack the car up again.

Awesome! Thanks for that update!
