Just have to shout about my new found discoveries. Tranny man tore down my glide and it's in good shape. Nothing wrong except the Rooster Comb was broke and the valve was hung in neutral. So what a coincident that it broke at the same time my throttle hung and I had to do a WOT shut down.
Anywho, was going to install a transbrake and found that the case has never been drilled and tapped for a modulator valve. So I get the idea to drill and tap it myself. (Powerglides have screw in modulators FYI). It's some kind of bastard size like 11/16" or 17mm. I have been doing machinist/tool & die work for around 15 years and never seen a thread like that. So I don't know what I'm going to do except change to another case. Apparently this case came from the factory as a manual shift valve body. And it is stock GM.
2nd part of the story is, I have another glide that has been in my uncles '64 Impala since new. But it also has the weak 1.82 planetaries and PLUS a stupid 14 spline (coarse) output shaft instead of the 27 spline (fine) splines.
Shit pisses me off. I see no options except pull both down and just use the case from the Impala and put the brake valve body and good clutches, drum, sprag, etc. in that case. Nothing is easy around here. And the darndest things can happen with this truck. Just 1 of many odd occurances. For instance I had a snap ring to break once in a new distributor that holds the reluctor wheel in place. Called MSD and they never heard of that. Gave me some timing night mares as well as pulling the timing cover to check and verify the chain had not jumped. Sent me new parts and it's never happened again. You guys would not believe the shit I can get into.
