What is the correct name for the automatic transmission in a 64 Cutlass? Is it a Jetaway or a ST-300? I need a torque converter for my car and I want to get the proper one. I've searched the web and am getting conflicting answers.

Thank you for your help

 

Both are correct.

 

I believe it's one in the same, Jetaway was the Olds version of the ST-300.

 

ST300 (Super Turbine 300) was the corporate name for the two-speed automatic with electric downshift and switch pitch (64-7 Buick and Olds) torque converter.

Jetaway was Oldsmobile's marketing name for it in an effort to distance itself from the transmission's Buick design origins. Pontiac called it Tempest Automatic and did not use it in their full-size cars as Buick and Olds did.

Despite their "Junkaway" reputation the ST300 was a very advanced automatic for its time. The Turbo 350 rendered it obsolete.

 

Thank you very much.

 

Should be a "switch pitch" variable vane converter.

Good luck!!!

 

The official name of the trans from Hydramatic division is Super Turbine 300. The Jetaway name was Oldsmobile marketing for that option.

 

Really? And here I thought it was "Powerglide".

 

Powerglide is Chevy 2 speed

 

I know ... I was just pulling Joe's chain.

It's always my feeling that it takes away from the joke if you have to explain it.
