Technical powerglide or powerslide

I have been fighting a powerglide shifting problem. It was rebuilt by a reliable shop. When it shifts to drive you hear a sound like WEE-OO then fine as can be. It's that sound that's driving me nuts!! It down shifts fine. checked downshift rod, fluid, mod valve band, vacuum reading. was told that it may be valve body.

Does the RPM increase before it finishes shifting?

Without video (with sound), we can only guess at what you're actually hearing.

 

A SWAG would be a slipping high clutch.

 

I've had one go OO-WEE but not WE-OObut only on hard right hand turns like coming off or on interstate off ramps.

 

Take a look at the vacuum modulator, maybe something happened on install.

WEE-OO doesn't sound right to me.

 

You have to careful tightening the valve body, are we talking an aluminum power glide?

 

A trans builder is talking to you, saying Let me in..

 

yes powerglide

He was asking if it was a cast iron (1950-1962) or aluminum (1962-1974) Powerglide. They are quite different as far as how they are assembled, although the gear trains are almost identical.

 

sorry, yes aluminium 64 belair. i have an appointment with the rebuilder 5/20. it dosen't seem to slip but i never put it to the floor and let it shift under high rpm. it really makes sound weee-ooo. grand kids came up with weee-ooo
