TREMEC TUET11430 Ford Mustang S197 T56 Magnum Transmission Conversion Kit

Closer Ratio Gears:
1st Gear = 2.66
2nd Gear = 1.78
3rd Gear = 1.30
4th Gear = 1.00
5th Gear = 0.80
6th Gear = 0.63
Rev Gear = 2.90

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

Nice package but what they don't tell you is to equal the gearing of the MT82 you would need 4.30's or steeper rear axle ratios, which is just another added expense.

2012GTCS

3500?! You can keep it....

MRGTX

Well... it's nice to know that the option is out there for the high horsepower cars.

My MT-82 has been great but I have to admit that the slightly clunkier Tremecs from past Mustangs that I have owned/driven were probably more enjoyable in some ways.

The ratios not matching the stock transmission are a bit irritating. There's nothing wrong with the stock ratios...nobody really complains about that. Why mess with it?

As for the price, I suspect that one would be able to find a used Tremec 6060 and rebuild it to their preferences for the same price...or less. I'd do some research on that before considering a this.

Glad to see this option available. Should have stayed with tremec in the first place.

These Tremec units are selling for about $2900. A new MT82 is about $3000 as well, and that wont handle the power and hard use the Tremec will.

Also, with the Tremec, you get rid of the 2-piece driveshaft and the remote shifter, going back to a direct mounted shifter, which has proven to be more reliable.

MRGTX

Any fiures about weight of this unit and efficiency losses with the Tremec? It's possible that they're not inconsiderable.

Those ratios are awful for a Coyote engine. Way too close together for the powerband of the engine.

Otherwise, a fantastic transmission, though.

hahnsolo78

Can't this be compensated with a higher rear gear?

hawkeye18

You can compensate for the overall low gearing with a higher rear end, but you can't compensate for the fact that the ratios are way too narrow. Those are ratios for an engine with a 5000rpm bandwidth, not a 7k+rpm bandwidth.

MRGTX

I disagree... maybe you could make a case that broader spacing might be better if you're exclusively drag racing the car... you might be able to get it down from three shifts to two in the quarter mile...(3.55 axle) or from four shifts to three (3.73 axle) but for all around driving, close ratios are much more fun and assuming you're rowing the gears with some proficiency, they will make the car faster in almost every situation.

The Coyote does have a nice broad power band but for performance driving, you want to stay 5,000+RPM...close ratios allow you to stay there.

I have driven quite a few cars where the gear spacing really hurt the driving experience and it stinks. Take a 2002-2004 Mini Cooper S for a ride some time, then drive a 2005-2006 where they revised the transmission....night and day improvement!! The Mustang seems to be pretty darned good in the ratio dept. I wouldn't change a thing.

06GT

I agree with MRGTX--those ratios are perfect and the same (minus first gear) as what's used in the BOSS302S World Challenge Car and stock GT500.

The ratios will keep you in the high RPM range, especially at higher vehicle speeds where you need to be up there to make enough power to accelerate rapidly vs. increasing aero drag resistance.

I dunno about you drag racers but this will be great for road racing.

Gearing sucks for Road Racing unless you go to 4.56 gears
3:73 rear gears, 7500 redline, 295/30 19 tires
1st 61mph
2nd 93mph
3rd 126mph
4th 155mph
5th 194mph
6th 246mph

06GT

Try 275/35/18, I've already mapped this stuff. The guys that are running World Challenge w/ these ratios and tire sizes are running 3.73 gears. It works. Could it be better, maybe--you'll only really use 2-3-4 w/ the 3.73s.
The BOSS 302R ratios are in this same vein (similar but different).

But you have usable rev range from 3000 to 7400, that gets you down to 35mph in 2nd gear at 3000rpm. You will be shifting less, and with the track key, the car can pull well from 3000 rpm. If you want to get something close to what the stock ratios are add a 4.30 and boom there you go.

OLOABoss

Nah. It doesn't pull worth a s*** from 3000 for good pull you need to drop into the meat of the powerband in each gear which is 5000 to 7500. Why lug around 6 speeds when you are only using 4 of them.

06GT

I guess we'll just have to agree to disagree.

OLOABoss

That is what makes this world so interesting
