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.

    • 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).

        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?

            I love it!

            I didn’t really need a new transmission but this one turned out awesome. I was happy to upgrade to a stronger trans and gain a 6th gear. It shifts a little rough sometimes but honestly it’s perfect you want an upgrade to support extra power output. The figment was a little rough, the actual shift knob levee would make contact with the boot retainer and tore my leather shift retainer boot a little bit no big deal. Install took a couple days but I had never replaced a transmission and was doing everything from the pilot roller bearing all the way back to the driveshaft. Took a little bit to figure out wiring for the reverse lights. And I have to rely on the manual reverse lockout instead of having the electronic lockout hooked up. I’m really happy with it and wouldn’t go back.

            Night and day difference

            2.97 first paired with the 4.10 rear is a great combination. Couple that with a smooth shifting six speed is a night and day difference from the old 3650. A must for anyone making 500 to the wheels. Should of got this along time ago.

            I have been building transmissions for over 40 years and I can buy this transmission and trust it to do what I need on the track and on the street. I recommend everybody buy a tremec for their race car. Street or Strip. it is worth the money.

            Get up and Go

            The T56 was the must needed mod for my current build. The stock T3650 choked my cars driveabilty and performance. I had the transmission installed at a transmission shop ($500-$800). The T56 transmission for the 05-09 S197 GT was a true plug and play, remember the 26 spline clutch and 26 spline driveshaft are required. I will say the power band increase is incredible and out performs the stock T3650. Get one, you’ll be glad you did. Next charger ;)

            NO RETURNS!

            Very disappointed. My fault for ordering the wrong transmission, but got NO HELP from AM to figure out a way to return. I have spent $20,000 with this company and they cut me loose without even a suggestion on how to work directly with the manufacturer. I realize it was my mistake, but nothing worse than being treated this poorly. Likely my last time on this site.

            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

            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.
