The
solution to 2005-up Ford Mustang S197 Shift problems
Are you plagued with shifting issues
in your 2005-up Mustang, including the 2011 and 2012
Mustang’s? Have you beefed up the motor with power
adders, pushing beyond the limits of the TR3650 (2005-2010) or Getrag MT-82 (2011-2012)? Is the 2-piece driveshaft
causing vibration issues at high speeds?

TREMEC S197 T-56 Magnum |
Coming in November 2011,(Update Dec. - anticipate release towards end of January 2012), TREMEC® is releasing an all-new
6-speed aimed specifically at S197 Mustang enthusiasts!
The new ‘direct-shift” T56 Magnum™ for 2005-up Ford
Mustangs represents a long awaited solution to the
semi-remote shifter woes experienced by many 2005-up
Mustang owners, as well as, TREMEC’s most significant
foray into the Mustang aftermarket since the days of
emerging 5.0 Fox-body performance!
Designed almost exclusively with S197 Mustangs in mind,
this new model draws from a combination of proven OE
(Shelby GT500) and racing (Grand Am Cup) technologies.
Featuring an application specific ‘direct-shift’
extension housing, the Magnum solves the issue of numb,
inaccurate shifts offered by the factory semi-remote
shifter; replacing them instead with crisp, clean,
confidence-inspiring throws. The S197’s exceptional
driver ergonomics are maintained; along with the added
ability to custom tailor shift action thanks to
TREMEC’s innovative “adjustable-bias” short throw
shifter, standard on every new assembly!

Other significant features include a slip yoke rear
interface, eliminating the need for complex 2-piece
driveshafts, and an SFI-approved steel bellhousing for
added safety in high-horsepower applications!
Installation is simple thanks to thoughtful design by TREMEC engineers and a TREMEC supplied swap-specific
crossmember. In most cases users can even retain their
factory clutch release system. Like all Magnum series
transmissions, the new model carries with it a generous
700 lb-ft torque capacity rating, and the choice of two
exclusive gear ratio combinations.
