The New T-56 Magnum is here.
  Order yours today.
 
Introducing the TREMEC T-56 Magnum 6-speed manual transmission, the long awaited and highly anticipated replacement for the original T-56.  Based heavily on the TR-6060, the all-new Magnum takes the best of TREMEC's current OEM design and manufacturing technologies and combines 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.
Call us for our Custom Magnum applications for Traditional small block or big block GM, Ford and Mopar:  (931) 646-4836
