Early model Jeep Wrangler vehicles equipped with an automatic transmission will require an upgrade of the stock automatic transmission. Bruiser Conversions has found through years of testing and development that the AW580/Nag1 transmission is the best available upgrade for the Jeep Wrangler platform. Our factory integration enables us to use the same language to control the Nag1 as if it was factory installedmodules and includes all necessary components to achieve complete functionality of the NAG-1 transmission through your vehicle's CAN system. The NAG-1, in its factory form, is rated for 550 HP and 500 ft-lb of torque. This transmission has been utilized in many makes and models of performance vehicle including Mercedes, BMW, Porsche, Sprinter Vans, SRT Challengers, SRT Chargers, and SRT Grand Cherokees.
All Cummins® R2.8 Turbo Diesel conversions offered by Bruiser Conversions are fully integrated into the Wrangler's factory systems to provide superior on and off-road performance.
