Default rear 4t60 mount (not dogbone)

I was trying to pull my motor and trans tonight and i'm not sure I got all the bolts to that rear d/* mount. I unscrewed the three 15 mil nuts through the subframe but it seems to be holding on the sub frame there. Are there any more nuts/bolts?

I have all the other mounts disconnected. So there is 4 nuts connecting that rear d/* trans mount to the subframe? I only saw the 3 that you get to through the bottom of the subframe. Where is the last one compared to those?

IIRC, there are 3, 13-mm head bolts holding the rear mount to the trans, and 3, 15-mm head nuts holding the rear mount to the crossmember. Removing all six allows the mount to move a bit while it stays on the crossmember. Unless the mount is bad, it can stay on the crossmember.

See techinfo article:

OK, motor with trans....should not have to drop the subframe.

Sorry, should have read more carefully...here is the techinfo for pulling motor w/ trans. Maybe something in there you overlooked?

OK i got it. basically the subframe was pushed bach and the trans was getting caught on all the steering crap. So, a buddy crawled under there and got the 3 bolts holding the mount to the trans and it basically came right out. (hes like 5 ft so he fit better lol)

It was pretty easy getting the thing out wasnt'. I thought I was going to have to fight that thing tooth and nail to get it out. Once everything got disconnected, it just pooped itself out.
