Tranmission mount/flex disc DIY.. Fill in the #'s...

Vibrations while driving, but not in idle or reverse, (goes away when I punch the gas and it switches to next gear [automatic]) so I hypothesize it's the trans mount, possibly flex disc(s).

So I raise car and put 4 jack stands propping her 18-24", put a jack with 10"x10" wood piece to support the trans pan to keep from denting. Fine.

Loosen or remove the brace with which? mm? sockets, then remove/replace trans mount and tighten to torque spec? for each mm? socket?

So, assuming I don't squoosh myself under my car, now I check the flex disc right up against the trans mount. If it's cracked/frayed, make a mark on the drive line so I don't f up the natural alignment leading to more effing vibration, then put car in neutral, spin disc and undo the 6 bolts, pry it out w/ a damn crowbar, replace flex disc and new bolts with loctite (blue shlt) on em, TORQUE SPEC #'s?

Then check other flex disc on front of car for cracks/frayed. Or not, drink beer, try to get friends to get car off of me. Why aren't these in the Wiki?

Really? No one knows the torque specs for the transmission mount screws or flex disc?
