Pontiac did not use a Powerglide transmission, ever. Neither did Buick or Oldsmobile.
They did use a planetary two- speed known as the Super Turbine 300 ,or the Jetaway, depending on the brand. The only thing that's the same as a PG, is the gear ratio (1.76 PG) . The BOP trans is a stronger unit than the PG in stock form, but it never had any aftermarket support.
Calling one of these 2- speed transmissions a Powerglide would be no more correct than calling it a Fordomatic or a Powerflite.

Now , for your question. Put a Turbo 200 3 speed in it and look for a Chevelle , Monte Carlo or 70 GTO 12 bolt in it in case you ever want to use a 4.33 ring and pinion.

Sorry Mark, but you are wrong. At one point, in the early seventies, there was a major fire at the plant where the 350 was built. GM made PowerGlides with multi fit cases to be installed in the place of the 350 transmissions in all GM cars. I actually had one of those transmissions in a circle track car, a Pontiac Grand Prix with a 400 Pontiac, later a 428 Pontiac, and finally a 455 Pontiac. The case was a genuine GM PowerGlide case, and would bolt to a Chevy, a Pontiac, a Buick, an Oldsmobile, or a Cadillac, with no adapter. I had to have the case because there was a rule that stated no adapter could be used.

Hey Mark,

And don't forget that the SuperTurbine 300 had a TH400 size output.

Thanks for confusing the issue .Now all the 2 speed Tempests and GTO's on Ebay can still claim they have a Powerglide in them.

How about Canadian Pontiacs? Transaxle Tempests? Technically a PG, I guess.

Hey everybody , Alan is right. Mark is wrong .Got it?

Turbo 350's seem to be the cheapest way to go. And you can't break the damn things...my trans builder built me 3 turbo 350's identical to eachother, one for my 9 second street car and two for my stocker. All stock internals except for the valve body, TCI sprag and some pump work. I can build 3 turbos (non lightweight) and have the same money invested in 1 powerglide. The gearset is what make it more expensive. Just my opinion.

Mark, I don't have any, I got mine from my friend Jim Beattie at ATI.

I didn't confuse anyone any more than you did. You said NEVER. That was not correct.

Don't take it so personal. Got it?
