Review & Installation Video

Tremec Magnum XL. Is your high performance S197 Mustang making more power than your stock manual transmission can handle? Then you need to upgrade to the Ford Racing Tremec Magnum XL T56 6-Speed Manual Transmission. This Tremec T56 is the perfect replacement for your old TR-3650 or MT-82 and has a torque capacity of 700 lbs./ft. making it ideal for high-performance race applications.

Built Ford Tough. The Ford Racing Tremec Magnum T56 Transmission is equipped with a 26 spline shaft and features a new extended length tail section with a solid mount direct shift design that is specifically engineered to eliminate the problematic shifting issues found with the stock semi-remote shifter.

SFI Approved. If you're using this transmission in high performance or racing applications, SFI Certification is critical so you can run your Pony at the track or strip, so you will be happy to know that the included steel bell housing is SFI approved.

Gear Ratios. 1st 2.97; 2nd 2.10; 3rd 1.46; 4th 1.00; 5th 0.80; 6th 0.63; and Reverse 2.90

Application. The Ford Racing Tremec Magnum XL T56 6-Speed Manual Transmission is designed for use in the 2005 to 2014 Mustangs equipped with a small block Ford 4.6L SOHC or 5.0L Ti-VCT V8 engine.

Installation Notes.

Users will need to convert to a 26-spline clutch disc and 1-piece slip yoke style prop shaft (not included).
Magnum XL transmissions are designed to accept the factory hydraulic release bearing from a 2005-current Mustang GT. GT500 bearings may also be used but will require a custom adaptor to maintain proper stack up (not included).
2005-2010 Mustang applications are a direct plug-and-play with regards to the speedometer. 2011-up models will require speedometer recalibration via ECU tuning or a separate plug-in signal converter from sine to hall-effect signal, such as the Abbott Enterprises ERA or Dakota Digital SGI-1 (Not included).

NOTE: Ships Continental 48 States ONLY. No Canada, APO/FPO, Hawaii, Alaska, Puerto Rico, Guam or Us Virgin Islands.

If shipping to a business, please include the business name. Also, after your order is placed, be prepared to let us know if you will need a Lift-Gate service. You will be contacted via email before your order ships.

What is the length of this conversion driveshaft on this page? ( u-joint center to center dimension ) thank you

Unfortunately the driveshaft shop does not publish measurements on their driveshafts.The Driveshaft Shop Aluminum One Piece Driveshaft listed on this page is designed specifically to work with the Ford Performance TREMEC Magnum XL T56 6-Speed Transmission when installed on 2005-2014 GT's

I saw that a McLeod RST twin disk, 26-spline clutch will NOT work with this transmission on a 2008 GT (per Q A on McLeod RST page)... A.M. staff said it needs it's own special clutch because "the bell housing and internals are different". So what clutch does work with this trans?

In order to provide the best option for your build due to the variations in horsepower and torque numbers your putting down we do recommend reaching out to one of our Mustang experts over phone or chat.

The Ford Performance TREMEC Magnum XL T56 6-Speed Transmission will work well with most setups and 4.10 gears, however this will come down to your individual build, and the type of driving you intend to do.

The T56 upgrade

The Story of my T56 Upgrade: I got a new clutch alongside a new driveshaft. However, when purchasing a T56 Tremec you will also need to get a kit for (at least the) 12-14 installations. We didn't expect this because we had asked on the questions page if there was anything else we would need and no one had had this issue before us. You can find the kit via silver sports transmissions website. This ran us an additional $200 or so as this was needed for the adapter, wiring, and lockout kits and such. I can not wait to finish the installation and begin breaking in the transmission

Smooth

Yes you need to get a 26 spline clutch and yoke to have the driveshaft work. (If you are already sinking $4,000 into the transmission, just get a better driveshaft too. Don’t be cheap!) The gear angle between 1st, 2nd, and 3rd are are close to one another, so getting off the line is incredibly fast. Also do yourself a favor and get a hat switch for the solenoid that locks out reverse, downshifting from 6-5 is scary how easy it is to accidentally slip into reverse so the reverse lockout solenoid needs to be able to turn on and off.

Gear noise

Works well. Need to get additional piece for your car for speedometer (unless you know someone who can work the ecu) as well as other componets to fit(driveshaft/clutch kits). Lots of gear noise at low rpms (below 3k) for gears 3 thru 6 if your keeping it low key thru towns. Was told by tremac that is normal, which i think is a bit sad. Getting into reverse was a hassle but close to a year now and has become a lot easier. This is a daily driver for me (as of now).

Best transmission

Best transmission swap I ever did. I have this teamed up with a rxt twin plate clutch. Shifting is so smooth, engagement is crisp and tight and locks into every gear you toss it into. Shifting takes no force at all it's just way better then the mt82

Parts and shipping

Transmission looks great, but be warned, once it's installed, at low RPM it will make a rough sound, which is normal. So to start things off, they sent the wrong driveshaft and the wrong clutch and flywheel combo. Waited 2 months for the transmission to arrive. Missed race week and cruising the coast due to their mistakes in the sells. It aggravates me that not all of the parts were sent to make this transmission work right. It was supposed to be a plug and play. Make sure to buy a clutch alignment part also. If yah don't your wasteing time trying to make it fit. Also with all of the phone calls back and forth with American muscle and their lack of nnowledge, they finally put me in touch with the head manager and he finally set me straight and had all my parts sent asap! Make sure you buy all the parts and make sure you talk to a manager before you purchase this item. Once it's all together, man what a change it makes! The transmission is a beast!

Stellar Transmission

This is an awesome transmission. If you are a novice mechanic do not attempt without doing research. You will need things such as a clutch, drive line, speedo converter box, and be able to do minor fabrication and/or modification. This is not a plug and play install. Expect electrical and mechanical work. After it is installed correctly it is AMAZING. No comparison out there to the feel of this box.

Boss 302 Tremec T56-MagnumXL

I had the Tremec T56 Magnum XL installed in my 2013 Boss 302 in July of 2015. I have since done a minimum of 6 track week-ends without a glitch!! Unbelievably solid. This transmission will go into the Boss with very few modifications but would advise to have done professionally. Much improvement over the MT-82 transmission which had to be re-built several times after only multiple sessions on a road course.
