Torque Specs for Upper engine mount/ transmission mounts.
Front tran mount-
1- 18 mm bolt through the front torque reaction mount. 74 ft-lb (100 N-m).
Rear tran mount-
3- 18mm bolts 37 ft-lb (50 N-m).
Upper Engine Mount-
2- 18mm nuts- 74 ft-lbs (100 N-m)
3- 15mm bolts- 37 ft/lbs (50 N-m)
Anyone know what the rest of the torque specs are for the rest of the bolts on the tran mounts?

Engine mount really doesn't have to be torqued, an impact gun will put it at/over the needed torque spec anyway (without one obviously, you then have to torque them)...the tranny mounts need to be torqued however. I told you it takes time nick lol, I woulda helped you man.

I just go with good-n-tight
I dont agree that TQ specs are highly overrated, they are very much needed all the time, especially if you are going to work on your car a lot and possibly take **** apart again.

I used to have all the specs. They're prob at home on my laptop. PM Aaron at TTR. I'm pretty sure he has em'.
I don't give a **** about torque specs anymore if it's not attached to the long block.
When I did my poly inserts, I torqued everything to spec and they were loose when we swapped out for the Powell mounts...

I did both tranny mounts and the engine mount in about 1hr in the dark with a flash light. I just tightened them until it felt tight enough. I didnt strain myself tightening them. All I need was a deep well socket, wrench, and a flash light. I replaced on mount at a time so I didnt really need a jack but used one for safety and poss help if the engine shifted.

I guess I am too manly then because I broke one of my engine mount bolts today
I got it out though thank god!
I found a grade 8 bolt at home depot that is a temp fix until I can get a hold of a new bolt from the stealership.
I now recommend using the torque specs. Learn from other peoples mistakes

wow the good news you broke the bolt coz helicoiling the trans housing is a pita; ya cross bolts are 41 at the front 46 at the rear dunno why the difference ( front is in steel rear is in alloy) be super careful with the other bolts, and the three lower rear bolts are less on memory i would say 26. I will say that if you go on allecotec.com Maven has an awesome thread on torque specs for every little thing. Good luck with the fix...

Front trans mount
mount to trans=66lb ft
trough bolt = 74lb ft
Rear tran mount
mount to frame=44lb ft
through bolt= 74 lb ft
These are from GM wheel hop kit install instructions.
