Found the following 2 items in my PG transmission pan today!! One is the broken tip of a dipstick, the other is a 1 3/8" bolt with an Allen head on it..
Is that bolt maybe something that fell down the dipstick tube? Or, is it a functional internal bolt of the transmission?
Yes, the truck is my '57 Panel. It has a 350 in it from a 1977 Camaro, and a Powerglide, but I do not know what the PG came from. The engine and tranny were in the truck when I got it.
The body of the tranny is aluminum, and it says "Powerglide" on the side. It also has the 14-bolt pan.
I seem to remember some transmission fluid filters being attached with that type of Allen head machine screw, at least on some of the early model Turbo 350's. From the general proportions of the screw compared to the dipstick piece, it looks like either a 10-32 thread, or maybe a 1/4"-28. Look at the valve body to case attaching bolts- - - -they're usually 1/4" hex head bolts, so I doubt if Allen screws would be used there. Jerry

I really think it was a rogue bolt. I checked the granny bottom and to your point, only saw hex head bolts. I also looked up PG internal pics online, and saw none showing Allen head bolts.
I put a new blue Moroso gasket on the pan and closed it up. It will be a while before this truck sees the road, and will be tested in the neighborhood first. That said, if that bolt was holding something together, I guess I'll have time to find out!
