Hey all... I've searched and Haynes manual isn't helping either.

What's the torque spec for trans cross member to subframe??? Also, the trans mount to crossmember?
TIA...

 

honestly man i wouldnt waste my time torquing the bolts with a torque wrench, just hit it with an 3/8 impact and call it good.

but if you want to, here ya go

-Transmission mount nut--77 ft lbs
-Transmission x-member to subframe--66 ft lbs

 

thank you very much... where did you find those numbers, if I may ask???

 

i have access to alldata from work, just looked it up there

 

I know this is an ancient thread but it has caused me a lot of grief. The torque specs for the transmission cross member outer bolts is way off and you will strip the bolts and the threads in the sub frame at 66ft pounds. Think about it, that is only 11ft less than the main transmission mount bolt which is like 4 times bigger!? I ended up going to 37ft and using blue lock tite. Hope this saves someone a lot of grief. Also, wherever you see those bogus torque specs, add a correction or delete the thread...

 

Old thread I know. However in the interest of the poor bastard that does a search looking for the info
