TREMEC's newly released transmission for 2011. This is a new addition to the T-56 Magnum line-up designed exclusively for 2005-up Ford Mustangs!

Known unofficially as the ‘S197 Magnum’, this new 6-speed model will feature a ‘direct-shift’ extension housing designed to eliminate the notoriously unpopular semi-remote factory shifter. Additionally, a slip yoke style interface will also make it easy to ditch the equally unpopular 2-piece driveshaft in favor of a more robust 1-piece arrangement.

As with all Magnum 6-speeds, TREMEC aims to put a 700 lb-ft. ‘seal of approval’ on the new Mustang units, and will eventually offer them with both Magnum ratio packages to suit a variety of street and performance driving scenarios.

Great solution for 2011-2012 Ford Mustangs with fragile factory Getrag MT-82 transmissions!

From TREMEC's Brochure:

Coming late summer 2011, the foremost name in performance manual transmissions, TREMEC, is releasing an all-new 6-speed aimed specifically at S197 Mustang enthusiasts! The new 'direct-shift' T-56 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 choice of two exclusive gear ratio combinations.

*2011-up models require speedometer recalibration.
**2005-2010 Mustang GT. Others will require minor modification

 

Gear ratios suck. Need a close ratio tranny.

Agreed, unless your doing a lot of top speed runs the close ratio of the getrag is better suited to keep the 5.0 in the powerband for dd use and most drag and track applications.

 

How about steeda's version:

Tremec's TR6060 features greatly increased torque capacity over the TR3650 used in production models and 6 forward gears. Gear ratios are 2.97 1st, 1.78 2nd, 1.30 3rd, 1.00 4th, .80 5th, and .63 for 6th gear.

That wont work. TR6060 has a different speedometer output than the MT-82, plus the gear rations are still less than ideal for a daily driven Mustang. Ford got it right with the gearing on the MT-82. We just all wish the transmission was a hair stronger.

 

Would it be possible to resolve the weak links with an upgrade kit? On my T56 I had synchros, shift forks, rings, keys and shoes all upgraded so it was upgraded to Viper spec (except for the shafts themselves I think).
