Torque specs

[steamroller]

Anybody have ALLDATA or a GM manual that has the torque specs for the transmission to bellhousing bolts for the NV4500? Haynes and Chilton manuals list 74 ft. lbs. but that seems awfully high for threads in an aluminum bellhousing.

Thanks

I'm not sure your year, so I used mine, but I think it says 35 ft/lbs. IDK.

Those are automatic specs, he needs the manual tranny to bellhousing specs ...

The trans is out of a 98, as far as I know they are all the same 95 and up, 92-94 had a different bolt pattern but still used an aluminum bellhousing. It says 74 ft lbs too .

40 ft lbs feels as tight as I'm comfortable with but I guess I can't argue with 3 different sources giving me the same specs. Hopefully they won't strip out on me

Thanks for confirming it

autozone says 74 for 98 nvg4500 2 or 4wd. all other trannies 35.

anyone know the torque specs on a 99 5.7 liter for a yukon denali?

I've seen 11 lbs and 15 lbs...

I have 1999 data, which bolts specifically?

sorry, I should have been more precise. I meant the toque specs on the spark plugs
