What Happened To My Powerglide?

[stroker1]

Went out Thursday night to test and tune. Tried the 1000 HP carb again and had bad luck, so reinstalled the old modified 750HP. Apparently didn't get the throttle cable bracket tight enuff, and it slipped and the cable end stuck into the cable sleeve. Long story short it was hung 3/4 WOT. So after lifting at the 1/8th there was no lifting. I shut everything down at 110+ mph in high gear and barely made the last turn off at a high rate of speed. At some point (don't remember when) I'm sure I probably shifted into neutral. But I'm fairly certain I did most of the slowing down with the tranny in high gear. After getting the throttle unhung, purging the engine free of nitrous, and restarting, the truck will not even attempt to move in any gear. What the heck could have happened to lose all the gears?? I thought maybe I hurt the converter, but how would I have screwed up just by shutting down at WOT??

does your glide still have the rear pump in it? if so, check the key on the rear pump. when i ran dirt roundy round cars, we used direct drive glides with in and out valves and if the key sheared on the rear pump it did the same thing

I am assuming it has all the stock components. Just has a manual valve body and kevlar stuff in it. Thanks for the advice.

From what I have read, seems that not all glides had a rear pump. Just the earlier ones. They also had a different valve body. Since mine is a manual shift only, I am assuming it has been changed to an aftermarket valve body. Don't know about the rear pump. Can I pull the tail shaft housing off and be able to identify if it has a rear pump? I believe one has a governor support and the other kind has the rear pump.

You can get the rear pump by removing the tailshaft housing. If I remember right the rear pump was used until 1966 then in 67 they went to the govenor support. ( I might be off on the years). My circle track glides were also manual shifted(put it in drive and take off in hi gear) and they still had rear pumps. I might be way off on your problem, I'm no expert, maybe someone else can chime in. I hope you get it figured out, keep us informed.

No rear pump on a race unit, only early stockers. Sounds like it may have broke the pump gears, not sure if your throttle issue is the cause. Get a pressure gauge, 0-300lbs, and check the pressure. The tap for low and high is on the servo cover, pressure should be over 150lbs. If nothing pull the trans.

Thanks, A local transmission guy just told me the same today. Sounds likely that is what happened. I'll check it before I pull it.
