Do I have a 3-speed or 4-speed Turbo Hydromatic Transmission?

Does anyone know if my 1965 Cadillac limo (with the 1964 carryover body style) have a 3-speed or 4-speed turbo hydromatic transmission?  My transmission selector is P R N D1 D2 L  Thanks

Hi

Based on selector you have 3-speed TurboHydramatic.

Thanks for your response.  I was told even if I only had 3 selections, it could still be a 4-speed transmission?

That's true. The shift pattern for the hydramatic on our cars is P N D(4) D(3) L R

- The Turbo Hydra-Matic used in 1964 de Villes, Fleetwood 60 Specials and Fleetwood Eldorados; and all 1965 Cadillac Body styles including the 1965 Fleetwood 75 Series is a 3 speed transmission. 


- The Hydra-Matic used in 1964 Series 62, Fleetwood 75 Series, and Commercial Chassis; and all 1963 body styles was a 4 speed transmission.

Thank you

Loud air moving sound within carb with cleaner removed

Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?

Vintage Air AC

Posted by Chase on March 21, 2024 at 5:55am 0 Comments

Hey everyone, has anybody done a Vintage Air AC/Heat setup in their car? I want to bypass the old vacuum setup and go with a Vintage Air Gen 2 model. Before I get started, does anyone have any experience with this? (Which model to go with, do’s and dont’s, etc.) It looks pretty involved. Any and all info/pics would be greatly appreciated. Thanks!
