Hot Rods TRANSMISSION POWERGLIDE TO 350 TURBO

I HAVE A 26 T street rod 327 chevy with a power glide and I paid a guy $ 1,000 to rebuild. It has many issues.I know I got screwed,not going back to him. I have a dumb question. before I buy are the( 350 turbo) size measurements bigger? tail shaft and overall size.

 

If a trans guy can't rebuild a PowerGlide, you really picked the wrong guy. They are about the easiest trans to rebuild I've ever seen.

 

I took the Powerglide out of my 67 El Camino and bolted to Turbo 350 in just make sure both of them are the same length

Country Joe thank you very much for the measurements.

 

I agree the guy can't successfully rebuild it.I did pick the wrong guy. He screwed it up so bad I don't even want another powerglide.LOL.

 

If the rear gear is 350 or higher numerical you should think about a 200r4 you get overdrive that way just my 2 cents

 

There are basically 2 lengths of aluminum Powerglides, the 28" long one, and the 25" long one (used in the "X" frame, 62-64 full sized cars). There is a 32" long one that was used in some "big" trucks; I've never even seen one of those, that's how rare they are. There are also 3 different length TH-350's; the short one with a 6 inch extension housing (the one you probably want if your Powerglide is 28" long), the 9 inch extension housing, and one with a ridiculously long extension housing (I'm not even sure how long that one is). So, if your Powerglide is a 28" long one, use a TH-350 with a 6" extension housing, and it'll bolt right in. There might be a difference in the splines of the slip yoke however; TH-350's have a 27 spline slip yoke, and Powerglides from 66 to 73 also had the same spline slip yoke. Powerglides also used mechasnical linkage for the kickdown/throttle control, while TH-350's use a cable. Should also be able to use the same flexplate. Happy hunting. I am Butch/56sedandelivery.

 

RICK, what does it do wrong? as said these are not hard. ONE THING wrong could be causing all of your problems. Pete

 

I love powerglides.

 

They don't get much respect around here

 

Why not? Cheap to build, bulletproof, work great in cars under 2500#. Of course, you can keep the cast iron ones.

 

They just don't. I think it's primarily the tall 1st gear ratio. Like you said, in a light car I don't think that's much of a problem.
