Transmission mount doesn't line up

JasonNC

I'm trying to mount a standard manual transmission that came out of a 48 Commodore Six Sedan into a 49 Super Six coupe that has an overdrive transmission that I"m not sure works correctly.  I didn't have a problem putting an overdrive transmission that came out of a 48 Super Eight sedan in the 48 Commodore.  After I got the manual transmission mounted to the engine in the 49, the transmission mount doesn't line up the holes on the crossmember.  At first I thought I had put the new mount on backwards, but when turned it around, same result.  Is the wheel base on a coupe that much different or did the engine shift while I had it jacked up?

Are the mounts measured the same distance on both trans ? Just a thought

I'll find out tomorrow.  That thing has beat my tail enough for one day....

How far off are you?  If your front engine mounts are old and soft the engine can easily move back an inch or so.

The motor mounts are new.  When removing the transmission, I jacked the engine up with a bottle jack that developed a leak.  When I went back the following day, it had fallen over and the engine had dropped considerably.  It looks to be about an inch off.  The game plan is to loosen the motor mounts and try to shift the transmission into place. Wish me luck.

You are on the right track, loosen everything off, lever in to position, insert bolts, and tighten.

Got it.  It helps to tighten the bell housing to the engine completely before seeking help on this forum. Once I did that, it was still tough but I didn't have to loosen the front engine mounts.  Thanks for the help anyway.

Funny. I think we have all been there before.
