Pontiac Trans

Can some one tell me what the trans is that runs behind the 383 Pontiac from 1963, its the one that has reverse on the far side from park.
Thankyou

 

Dual coupling hydramatic, Pontiac called it Super hydramatic in that year.

 

not sure which one you have but first i guess your talking about a 389 eng.
there were 2 auto trans
Jetaway Controlled Coupling Hydramatic
"Slim Jim" Roto-Hydramatic

 

Thankyou
Your right on the 389 I was somewhere else with the 383

 

Both the slim jim and Jetaway have reverse at the bottom. Which car did the engine/transmission come out of? Catalinas, Venturas and Grand Prixs used the slim jim, Star Chiefs and Bonnevilles used the Jetaway.
