Broken Tranny Mount? alright, the other night i shifted into 3rd not hard not soft. i just hit it and i got out of it around 3k and i heard a snap, and every day after that the shifter started to move about an inch when the engine was under load. well today i tore everything apart and looked at the tranny mount and motor mounts and everything was fine. the motor torques about an inch in either direction when i rev it but the shifter moves also. it never moved at all before i h eard the snap. so what is my problem?

deffinatly a trans mount, i couldnt tell mine was broken untill i took it off... while your down there might as well change the torque arm mount to polly energy suspension in like 18 dollars i think......CAUTION!!! dont drive to long with that broken mount....drove mine for about two weeks and ended up breaking a motor mount because of the tranny moving so much

I'm having the same problem right now. I replaced my trans mount with a poly one that really stiffened up the shifter, but it still moves left to right quite a bit under load. I think it is the motor mounts. I've already ordered them and should have them very soon. I'll update as soon as I get them and install. I also ordered the torque arm mount and will drive after each install to test and see what fixes it and let you know. I think we have the exact same problem..

This was posted in a similar thread. I can't imagine it being much different for an LS1. I'm going all Poly as well

remove the mounts
The mounts are rivited together, so you'll need a 1/2" and 3/8" drill bit to drill the rivits out.
Install the new mounts, and re-sandwhich the mounting plates toghether using the supplied hardware.
Re-attach the mounts. I left them a little loose so I could wiggle them around. Re-aligh the through bolts and tighten it all down.
I had the most difficulty getting them realigned. It helps to have someone else operate the jack up/down while you try and slide the through bolt back through.
Tighten everything back up....done!
