Transgo Performance RFE-5B-HP High Pressure Tuneless Reprogramming Kit for Mopar RFE Transmissions

The Transgo Performance RFE-5B-HP High Pressure Tuneless Reprogramming Kit is an advanced transmission upgrade solution designed specifically for 2011-2018 Chrysler, Dodge, RAM, and Jeep vehicles equipped with 45RFE, 545RFE, 65RFE, 66RFE, and 68RFE automatic transmissions with 5-checkball valve bodies. This innovative kit utilizes Transgo's patent-pending Tuneless Technology to internally reprogram your transmission for enhanced durability and performance without requiring external computer tuning.

Key Features and Benefits:

• Increases maximum line pressure to 210 PSI (30% increase over OEM 160 PSI) for improved clutch holding capacity
• Fixes common RFE transmission issues including rough lockup, low line pressure, TCC slide bang, slip codes, and overnight converter drain back
• Prevents overdrive friction failure on engines with increased horsepower and torque from aftermarket tuners, chips, or programmers
• Eliminates driveability side effects and limp mode issues associated with external PCM programming
• Provides re-calibrated pressure curve that mirrors throttle position and torque demand for cleaner, firmer shifts
• Includes recalibrated converter and pressure regulator systems with patent-pending internally balanced calibrations
• Features optional triple-disc converter calibration valve for modulated converter clutch apply
• Contains heavy-duty accumulator plate, snap ring for input drum, and accumulator calibration components
• Includes triple separator plate with gaskets and complete installation instructions

This comprehensive kit is ideal for performance applications, towing, and vehicles with modified engines that demand increased transmission holding capacity. The Tuneless Technology approach allows increased transmission operating pressure without triggering fault codes or putting the transmission into limp-in mode, making it the superior solution for high-performance Mopar applications.

Note: Designed for transmissions with 5-checkball valve bodies only. For 7-checkball valve bodies (1999-2010 models), use part number RFE-7B-HP instead.
