The GR700A kit is the newest version of the full bolt in T56 Magnum-F swap kit for the stock motor equipped Honda S2000's. 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 dampens noise and fits like OEM. These are a direct bolt on kit. 

This kit includes a brand new Tremec T56 Magnum-F, GR cast aluminum bell housing, factory Magnum-F shifter with GR 6" billet shift lever, 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 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 a 1999-2009 Honda S2000 (S2k). The shifter sits perfectly in the factory location.

This bolt-in kit includes:

    • Brand new Tremec T56 Magnum-F Transmission (comes with 1 year manufacturer warranty!)
    • Grannas Racing Cast Aluminum Bellhousing 
    • Full chromoly transmission crossmember (pictures may vary)
    • Prothane Polyurethane T56 transmission mount + hardware
    • Grannas Racing 6" billet shift lever
    • Includes bluetooth wiring harness
    • Multiple F20/F22 to T56 clutch options
      • 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 both stock rear and the Grannas 8.8 Rear (or any other 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. 

    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

    We take a brand new Magnum-F Trans and give it a full REM polishing and Cryogenic treatment of the gear set. We do a 1st thru 4th carbon fiber blocker ring upgrade. Then include upgraded bronze Fork Pads on all forks. Also includes sprayer bung mod and case mods to fit Supra tunnel. Read more here: GR1000 Transmission

    *GR1000F (quicktime bellhousing recommend for racecar use)
    We take a brand new Magnum-F Trans and faceplate 1st-4th gears. Includes custom billet shift forks, bronze fork pads, and then we do a cryogenic treatment of the gearset, and then do a rem polishing of the gearset. Read more here: GR1000F Transmission  


    The OEM S2000 tunnel does require some slight tunnel massaging/modification in order to clear this transmission but it is not terrible like you have to do with the giant CD009 transmission. So I do recommend this as the "best fit" high power manual transmission.

    The T56 Magnum transmission works great with the factory Honda rear gear with 4.10 ratio. It just so happens the stock Honda rear gear is what I consider the best final drive ratio for most street cars!
