Powerglide reverse only

I have recently rebuilt a powerglide and today backed it out of the garage for a test run. I am a little confused because when I shifted from reverse to neutral and then drive and Low I was always in reverse? Once I got the car back into the garage I dropped the pan and viewed the shift linkage it appears to be moving the manual valve as it is supposed to. So I do not believe it is a linkage issue.

My question now is could I have somehow installed some of the valve body wrong not allowing the hydraulics to redirect to the proper ports for the forward direction? I was hoping someone has an idea as to what i did wrong. Any advise would be greatly appreciated. And maybe some pictures of the valve body or a link to some pictures.

the powerglide is all stock.

after looking closer I seen that the manual valve was not being moved by the shifting mechanism. I overlooked this the first time in a rush and must have overlooked this obvious mistake. Anyway after connecting it up the proper way it shifts through all the gears..
thanks for all the help.

Amature,

I'm glad I've found this thread, I'm having the same exact problem! Do you have any pictures of where/what the manual valve is? was it as easy as just dropping the pan and rummaging around or did you have to take the whole transmission out?

Thanks!

Aluminum Powerglides are known for breaking, or stripping out, the "rooster comb". That's the internal piece of shift linkage that indexes the manual valve, and clamps to the shift rod after it passes through the case. One other common mistake concerns the use of a rear support gasket. In models with a rear pump, there is NO gasket used, just the wear plate; the gasket is used with models NOT having a rear pump (about 66 and newer transmissions). If a gasket is used with a rear pump model, the gasket blocks feed passages, and you'll have no reverse, and a single forward speed transmission. That, I learned from "experience".

Butch a.k.a. Junior Stocker,

Thanks for great info! I definitely had experience with stripping the rod that the rooster comb lever sat on. I had immediately replaced it. The problem I've found is the same as Amature, the manual valve wasn't seated right on the lever knob! Completely solved!

Thanks!
