Tuneless High Pressure Reprogramming Kit Mopar

The TRANSGO Tuneless High Pressure Reprogramming Kit for Mopar RFE is a comprehensive transmission shift kit designed to recalibrate and optimize the valve body and internal hydraulic programming of Chrysler, Dodge, and Jeep RFE five-speed automatics without requiring external tuning hardware. This reprogramming kit addresses factory shift characteristics by replacing worn valves, springs, gaskets, and seals with precision-matched components, allowing operators to achieve firmer shift engagement and improved transmission response across all gear ranges.

The kit includes all necessary internal components—valves, springs, gaskets, seals, plugs, shims, and hardware—plus specialized installation tools required to access and service the valve body without removing the transmission from the vehicle. The tuneless design means shift characteristics are controlled entirely by mechanical valve geometry and spring pressure rather than electronic controllers, making this kit suitable for vehicles that operate in high-heat or high-load conditions where factory programming may cause delayed or soft shifts. Installation requires competent transmission knowledge and proper torque specifications to ensure seal integrity and valve clearance.

This TRANSGO RFE-5B-HP kit is engineered for 2011–2018 Mopar RFE transmissions commonly found in Ram trucks, Durango SUVs, and Jeep Grand Cherokee models. Users seeking improved transmission response, reduced slippage during towing or hauling, or corrected shift timing in aging transmissions will benefit from the mechanical recalibration this kit provides. The complete component set and tool inclusion eliminate the need to source parts separately, making this an efficient solution for transmission maintenance or performance restoration work.
