Can anyone tell me the automatic transmission that came as standard equipment in the 66 442

2 speed jet-away. Some call it the junk-away. A 350 turbo will bolt in it's place and you can use your same drive shaft.

Technically it was RPO M32, a special duty Jetaway (AKA Super Turbine 300). The 1964-67 Jetaways used a switch pitch torque converter.

66-3X2 442

I believe that's the first time I've heard the Super Turbine 300 used by someone other than me. When I ran my Chevy's in NHRA/IHRA Stock Eliminator I used A-! Automatic Transmissions and Convertors. A-1 was a premier vendor for such parts and Marv Ripes the owner told me he used the Super Turbine 300 clutches in the powerglide trans. That was the first place I heard that term used back in 70's. Thanks Joe for bringing back some good old memories.

Buick called them Super Turbine 300's and called the Turbo 400 a Super Turbine 400.

joe_padavano

Actually, GM called them ST300s. "Jetaway" was just Oldsmobile's marketing name, like "Rocket V8".

Then I guess Super Turbine 300 was Buicks marketing name since that was what they were called when I worked for a Buick dealer from 1964 to 1966.

ST300 was the GM transmission name from Hydramatic Division, just like TH350. Olds decided that they needed a special marketing name. Buick did not. Pontiac also called it the ST300.

Buick called it a Super Turbine 300. The DID NOT call it a ST300 which was the GM name. Seems different to me but what the hell do I know. I only worked for a Buick dealer during the period. Of course I should realize I am talking to the guy that knows everything.

ST = Super Turbine

TH = Turbo Hydramatic

Sorry, but you are reading waaaay too much into my laziness.

redoldsman

Believe what ever you want to believe and I doubt you are lazy.

It doesn't really matter what they were called. It was the same transmission across all three lines. The only difference was the versions for heavy duty applications.

joe_padavano

The primary difference was that Buick and Olds used the switch pitch converter behind V8s for the 1964-67 model years. Pontiac and six cylinder Buicks and Oldsmobiles did not use the switch pitch. The version used behind big blocks in the 1965-66 442s were beefed internally and used different calibrations, obviously.

I presume the one year th400 switch pitch converter was similarly beefed in 67, to borrow your term.

Pretty sure the switch pitch started on 65, ended before the 68 model year.

joe_padavano

The 1964 ST300/Jetaway came with a Switch Pitch converter when used behind V8 engines. My 64 Vista has it. 1967 was the last year for it in both the ST300, TH400, and TH425.

I guess I should have clarified, I was referring to the 400. Never messed with a Jetaway other than swapping in a 350
