Also known as Torqueflite TF-6; Torque Command 6; type B; 30RH (A904); 31RH (A998); 32RH(A999) Versions of this transmission were used from 1960 to present. Starting in 1978 some versions had a lock-up clutch inside the torque converter. There were MANY variations over the years and MANY parts do NOT interchange from year to year or model to model.

Rear cooler line is the cooler return line.
