I put this in a separate thread for more visibility and its something you should know if you are installing a MGW shifter. I called them
today and asked why they don't include a torque spec on page 10 of their installation guide, especially since they make a point
of warning you not to overtighen the bolts. I was told they cannot get the torque specs from Ford and that some tranny castings are aluminum and some are cast iron and they would both have different specs. There is a danger of stripping the bolts if you use the incorrect torque which is another reason why they omit it.

Solution is to use wrist strength, not shoulder strength (no gorilla grips!!) to tighten and make sure the lock washer is flat. Basically use common sense. Also if you are using a gasket instead of the sealant they provide, you should use removable loctite (blue) on the threads of the bolts as the sealant does a better job of holding down the shifter and without loctite, the gasket only may allow the shifter to loosen up.
Hope this helps.

 

Good info. Loctite with the gasket is pretty important.

 

The instructions with the Roush I just installed said 15-20 ft. lbs. of torque.
That is def. not going to strip anything if tightened criss/cross gradually until torque spec is reached but you bring up a good issue.

Sometimes what is wrench tight for one guy is way tighter than the next guy depending on how strong they may be.
