This kit is perfectly setup for a 1993-1995 Mazda RX-7 with Toyota 2JZ or 1JZ engine swap. The shifter sits dead center in the factory location.

The GR700A kit is the newest version of the full bolt in T56 Magnum-F swap kit for the FD3S RX7. The A in GR700A stands for Aluminum bellhousing, as this kit comes with the Grannas Racing cast aluminum bellhousing. This bell is superior for a street car as it is far superior at dampening noise. It also has a large inspection hole which makes servicing a release bearing much easier. youtube.com/watch?v=aiByNjTQTL4

This kit includes a brand new Tremec T56 Magnum-F, bell housing of choice, Grannas Racing multi-position offset shifter, and chromoly transmission mount, bluetooth wiring harness, bellhousing index plate, and all hardware required. Driveshafts and clutches are optional, but recommended to make this an easy bolt-in experience. There is NO CORE charge for our transmission kits.

The wiring harness we include makes for a super clean and simple wiring job. But not only that, but it has a bluetooth module with you can play with the settings such as reverse lockout control, and convert and adjust the T56 speed signal to make the factory speedometer work perfectly. No more need to cut down the reverse lockout spring or wire in a manual reverse unlock switch, this will auto unlock reverse under a set MPH (defaults to 4mph)! All of the settings are all adjustable through your smart phone with an app, and will hold the settings permanently after set.

If you add up the cost on all these parts, you will see that I am matching prices with big name speed shops like Summit and Jegs. Not only do I match big box store pricing but I put it all together in a one-stop-shop package deal and also provide you with the little details they don't... like proper hardware for EVERYTHING, down to every last nut and bolt, we pride ourselves in giving making this a true complete package. We aslo trim the transmission case and install the shifter on all complete kit purchases. We are not just drop shipping an item and taking my cut of profit like these big name stores. Oh, and did I mention we have actual product support as well, with more knowledge and technical know-how than you will get anywhere else! Try calling Summit/Jegs and asking for help on your import car!

The stock tremec Magnum-F is rated at 700 ft lbs of torque. These T56 Magnum transmissions are FREAKISHLY strong and will outlast any other street car transmission available. Everything I build is tested rigorously in my racing program, so you can rest assured what you get is going to install beautifully, work flawlessly, and be durable... No one else pushes these parts to the level I do! You can rest assured all parts go through my quality control and abused to test the limits of these TREMEC transmissions!

In 2016, I built and tested the first Supra T56 Magnum kit in my own car to be a direct replacement for my broken Getrag V160. We all know the V160 is a great transmission, but V160 parts have become impossible to find. Rather than risk breaking your transmission and not being able to repair it, I suggest swapping to this setup and put your V160 away for safe keeping. The Getrag transmission will continue to gain value as parts become even more scarce, but repair costs will also climb with the decreased parts availability.

These transmissions have great aftermarket support, aftermarket racing gearsets, and parts readily available for when you ruin a synchro or break a gear tooth. We have upgrades for BIG power street cars (GR1000A) and Orange Man Bad spec race boxes (GR1000F) as well.

Our bolt-in kit includes:

    • Brand new Tremec T56 Magnum-F Transmission (comes with 1 year manufacturer warranty!)
    • Bellhousing of your choice (GR700 = steel SFI bell. GR700A = street car aluminum bell)
    • Full chromoly transmission crossmember
    • Grannas Racing Rubber mount (for street car "A" kits)
    • Grannas Racing billet offset shifter, moves the shift point back and places shift point perfectly in tunnel. SEE PICS!
    • Includes bluetooth wiring harness
    • I recommend the "close ratio" TUET16362 - 2.66, 1.78, 1.30, 1.00, .80, .63 but i can also get this in "wide ratio" TUET16363 - 2.97, 2.10, 1.46, 1.00, .74, .50
    • Driveshafts are available in aluminum and carbon fiber for almost any rear end combination.

All transmission builds are created from brand new TREMEC T56 Magnum-F's, NO USED transmissions EVER. These are then built to your specs. Choose the power level you need. 

GR700 / GR700A
This is a brand new T56 Magnum-F direct from the Tremec factory, and I match the big box store prices. You can buy from me and get real experience or try calling the big name stores with your swap tech questions and see what kind of service you get! Read more here: GR700 Transmission

NOTES
----------------------------------

The OEM manual tunnel WILL require slight trimming at the front edge of the shifter hole. You will need to remove about 1" forward to clear the shifter. This however does eliminate the need for a relocation shifter which can have very detrimental effects on the shift feel. So its a trade off to have to cut the tunnel, but you get a much better shifter setup. In my opinion this is well worth it.

PLEASE NOTE: The T56 Magnum transmission gearing works great with the shorter gearing of 3.90 and 4.10 gearing. All three of these ratios work well with the Magnum swap. 

More info on gear ratios can be found on this page I created T56 Magnum vs V160. The absolute best rear ratio is 4.10 which makes this transmissions gearing identically match the V160 gearing.
