Right from the 1964 Pontiac Dealer's Sales Manual - 1964 LeMans standard features included the 215 ci 6 cylinder...

Here's a Super-Turbine 300 2-speed that I pulled out of my '64 Tempest. It's an air-cooled unit with a dual-pattern bellhousing, it has both BOP and Chevy bolt patterns. Note that in the second picture you can see the stamped sheetmetal cooling shroud attached to the backside of the torque converter, all six-banger cars used the air-cooled transmission.

The Chevy pattern was used with the original Pontiac 215-six which is exactly the same as a Chevy 230-six except for the bore size (3.750" vs 3.875").

I seriously doubt any Powerglide was used in a any early-sixties Pontiac A-body cars, pretty sure they didn't show up until the late '60s and were rarely used at that. With the ST-300 being built with the dual-pattern bellhousing the Powerglide wasn't needed when a 2-speed auto was used behind any Chevy-derived six.

Thanks for the info everyone. I just found out that the '65 GTO does have a 3 speed automatic and the window sticker says "3 speed------synchromesh "!! (Not an automatic) (Not numbers matching either). Someone has added a later model automatic with a console out of a '67.
It pays to know your Pontiacs!

Two more pages from the parts book showing full transmission assembly part numbers. Just in case you managed to shell one out that bad. Slightly different numbers. But earlier or later editions may be a little different. They were changing that stuff constantly. The sketches of the 300 are to grainy to tell if they had a dual bolt pattern. But b-man shows the proof.
Page C-935 is from the 300 transmission section. Page C-907 is from the Powerglide section. I don't know if it was an early year to late year difference or maybe a single plant where Chevy may have been built on the same line. I can't find anyplace in the parts book where that may be explained. And even JohnV probably doesn't want to try to research that.

Right, the Powerglide was Chevy and most think that all GM 2 speed autos were called Powerglides then.

W.E., you have a glitch in your list, all of the Super Turbines in '64 V8 Tempests were water cooled. The p/ns you list check out with the Inspector's Guide but the 326HO auto was water cooled.

b-man, I am certain the air cooled Power Glide was used in some '64 Tempests with the base 6 cyl engine.

I'm pretty sure somebody here had one and mentioned it some years ago.

It was '64 only and service parts can be found in the MPC.

The Inspector's Guide explains that when the Power Glide was installed with the 215 6 cyl, a secondary trans code of numeral "1" was to be stamped at final assembly, added to the basic engine manifest code so that the trans code would read "Y1" (the auto engine codes were 87Y for the export version, 88Y for the 49 state version, and 89Y for the mid year K24 Calif. closed circuit crankcase vent version).

No need to provide service parts or come up with an identifying trans code if they were never installed.

I have speculated that they were most likely to have been installed at the KC and Balt Plants since those Plants were Chevy operated. But I'm pretty sure those Plants would install the air cooled Super Turbines so it was not an exclusive deal. And I really have no reason to believe the Power Glide was never installed at the home plant or Fremont.

For all I know, it may have been an early year thing although I don't find any indication of that in any documentation I have but I am certain the Power Glide was installed in some '64 Tempests.

So next time somebody says Pontiac never put a Power Glide in a '64 Tempest, you really should say, "except...".

John I questioned the listing even as I copied it but there it was.......The 1367757 326 HO 326 4 barrel trans, air cooled, revised catalog dated 7-1-64. Checking the 1966 catalog shows they made the correction and then call it H20 cooled.
