Default Changing the Trans mount- any sugg?

After the first long drive that we've taken in the Vette, my dad noticed that the tranny was shifting around.

We climbed under the car and started inspecting, and sure enough, the tranny mount is torn. We've ordered a new Energy Suspension one to replace it; does anyone have any suggestions for getting the old one out and the new mount in? I'm assuming we just put a jack under the bellhousing to take some pressure off, unbolt it, slide the old one out and the new one in, right?

If there's any tricks for this that anyone else knows and would be happy to share, I'd appreciate it...I've done motor mounts on several other vehicles, but never changed a tranny mount...

thats pretty much it but jack up on the trans pan, put a piece of wood on the jack so you don't bend the pan.

Don't you have to remove the cross-member? I did...

Maybe...I dunno... I know with motor mounts you just put a piece of wood on a jack and jack up the engine enough to take pressure off of the old ones, then unbolt & slide out the old ones, slide the new ones in. Tranny mounts are a different animal, from what I know...

I had to remove the crossmember to get to the upper bolts...I guess if you can find the right angle to get a wrench in there you don't need to, but I wouldn't try to fight it

Right. I remember removing the cross-member to change my exhaust hanger's. While I had it out, I discovered my trans mount was in need of replacement. I replaced it and then re-installed the cross-member. Although you may be able to, I would'nt want to try it with the cross-member in...it was a beyotch!

He won't be removing the crossmember if his transmission is a manual...

I didn't have to remove the mount on my 79. However, I'd give the job a 1/4 PITA.

The crossmember is fixed on manuals (not removable). On my 81, you could change the mount without removing the crossmember but it would definately be a little harder.

Yeppers, it's a manual transmission, 4 spd.

Sounds like I've got it down as to what to do, and that while it's not going to be easy, it'll be easier than say, replacing the steel fuel lines (which I understand involves lifting the body off the frame to put the lines in)

Nah...that's easy. Just run rubber fuel lines outside the frame and use a lot of nylon tie-wraps!
