    Racing Edge. The JMS LaunchMAX Splice In Digital Trans-Brake Kit for 6R80 Transmissions helps your 2011-2017 GT or V6 Mustang leave the starting line like a thunderbolt. This splice-in trans-brake unit, when combined with your choice of momentary switch (sold separately), gives you a strong edge in starting line RPM at the dragstrip, potentially propelling your 'Stang well into the 9-second zone. You can choose between ground or +12 volt activation. Since the LaunchMAX is all digital and contains no moving parts or relays, it achieves instantaneous trans-brake release times and is not engineered to raise the line pressure in your Mustang's transmission.

    All Digital Design. This JMS trans-brake module is compact and completely digital, meaning that it has no moving parts inside to wear out over time or fail under stress or repeated use. The unit is completely waterproof to boost its longevity regardless of driving conditions. The LaunchMAX can be used with any custom tune ECU file and can be removed at any time if necessary without adversely affecting the car's function.

    Splice-In Installation. The JMS LaunchMAX requires approximately one hour to splice into the system. It connects directly to the transmission harness, without opening or modifying the transmission itself. The kit includes a 7-foot wiring harness and instructions.

    Application. The JMS LaunchMAX Splice In Digital Trans-Brake Kit for 6R80 Transmissions is built to work with all 2011-2017 GT and V6 Mustangs equipped with the 6R80 transmission.

    I installed the JMS transbrake kit for my 6r80, per the instructions. My question is... When the transbrake is enabled, shouldn't it (my car) be able to rev past 2100 rpm. I can mat the gas peddle but it still only revs to 2100. Is there anything I can do to get it to rev at least up to 2500 rpm.

    • The rpm is not limited by the JMS LaunchMAX Digital TransBrake Kit for 6R80 Transmission it is limited by your converter. If you would like a high RPM to leave the line a higher stall converter would help with that.

    Have a 14 gt and a circle d converter. I have read using the launchmax and taking my car about 3000rpm can put the car in limp mode if held more than 2 seconds. Is this problem remedied with a tune?

    • We have not experienced issues with the JMS LaunchMAX Digital TransBrake Kit for 6R80 Transmission causing the car to go into limp mode, however this could be remedied with a tune if you experience this with your setup.

    default-question-summary if i have this installed when i am not using it will the car still be able to rev to 6 7 8 thousand rpms? i am just making sure while not using it can i still rev up to \x22show off\x22

    • Yes, with this installed correctly and not in use the vehicle can still be reved to that RPM range without issue.

    Where can i purchase the push button?

    Do you have to have a button ? And if so can I purchase on website ?

    • This would require the use of a button, we do not currently have a specific button for this kit on the site, however, you can find a generic button at your local hardware or automotive store.

      splice in transbrake

      Product does exactly what you buy it for! With a stock torque converter for a v6 mustang, with the button pushed you can rev you stang to between 2000 and 2200 rpm and then let the button go, Launch like never before. My 60 foot times dropped from 2.2 to 2.02 seconds.

      Cheap, easy to install and works great

      Amazing transbrake. Very easy to install and works flawlessly. I wished it included the button to avoid going through the problem of finding one.

      Having problems getting the rpm over 2500rpm

      Great buy for the car worth the money. But for some reason it won't let me get the rpm over 2500 to launch. Is there a rev limiter or something I have to do to make it so I can launch at a higher rpm?
