TUET16885 2.97 first .80/.63 OD

Introduced in the spring of 2009, the TREMEC T-56 Magnum 6-speed manual transmission, was the long-awaited and highly anticipated replacement for the original T56.

Based heavily on the TR-6060, the all-new Magnum took the best of TREMECs current OEM design and manufacturing technologies and combined them with the most popular features of their intensely popular TKO 5-speed.

The result is the smoothest shifting, greatest driving, strongest, and most versatile 6-speed aftermarket transmission TREMEC has ever produced
