Can Anyone Shed Light on Mystery Bolts?

Lizard Dog · Sep 15, 2018

This morning I reinstalled the access cover on the bottom of the transmission bellhousing. As I did I noticed the two bottom bolts, (#9 in the attached drawing), don't seem to serve any function. They don't attach to the transmission, just float in the cover.

What are they for?

On the Civi trucks there are two braces. They go from those bolt holes to two brackets mounted behind the motor mounts. Not all civi trucks came with these. The military did not purchase them either. But all TQ covers are drilled and tapped to accept them

Aha! Thank you Ken! Anyone here add those bars on CUCVs? I can't think of clear benefits to them, but curious.

Oh NO. Not the rod question again. I installed a few from the transfer case to the engine block. I liked them. I used the vehicles hard off road.

The man reason is like CUCVRUS said. They are for trucks that are used for hard offroading. That way you don't break the bell housing during a hard landing.

Is that rod specific to a 400/208 or will one from a 700R4/208 fit?
thanks

I removed the one pictured from a 1990 GMC Jimmy with a 350EFI / 700R combo. The bolt holes are threaded in the NP 208 transfer case. I think M16 metric thread.

The NP 205's had them also , along with 2 short braces to the motor mounts.

I have all 3 installed on mine. had to source them from a wrecker. There are several different lengths on the motor mount to bellhousing braces. Couldn't find the right size so bought a set, cut them and welded to shorter length.
