Matthew, the Tremec is manufactured by TTC (Transmission Technologies Corporation), a joint venture of DESC and Dana Corporation. They supply light and medium duty transmissions to the OEM manufacturers and the aftermarket. 5-speed transmissions include the T45, T5, TR3450, TR3550, TR3650 and TR4050. The T56 is their 6-speed box.
Will the T56 work with my 351C? Were these transmissions put in any common production vehicles that I may find in a boneyard? Does the T56 have an overdrive gear?
