The GR "A" kit is the street car version of the full bolt in T56 Magnum-F swap kit for JZ swapped MK2 Supra's. The A (previously called 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.
This kit was designed for the Tremec T56 Magnum-F and includes bell housing of choice, chromoly transmission crossmember, bluetooth wiring harness, 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 install. 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/dash 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.
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. I am not just drop shipping an item and taking my cut of profit like these big name stores. I also include a wiring harness kit to make the wiring side of things easy and seamless. Oh, and did I mention I have actual product support as well? Try calling Summit and asking for help on your t56 swapped 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 a V160 or CD009 at high power levels. Everything I build is tested rigorously in my racing program. 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 6-speed transmissions!
I have been building these T56 magnum kits since 2016, with over 2000 transmissions sold, I have the most experience and knowledge when it comes to setting up these transmissions behind import engines.
These transmissions have great aftermarket support, aftermarket gearsets, and parts readily available for when you ruin a synchro or break a gear tooth.
This is perfectly setup for JZ swapped MK2 Toyota Supra. The shifter sits perfectly in the factory location.
This bolt-in kit includes:
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.

The OEM MK2 tunnel will require tunnel massaging/modification in order to clear this transmission but it is not terrible considering you will be getting a high power capable manual transmission.
The T56 Magnum transmission works great with a rear gear range of 3.70-4.30 ratio, with 3.90-4.10 usually being the sweet spot.
