TransGO Reprogramming Kit™

Fits all 45RFE, 545RFE, 65RFE, 66RFE, 68RFE 1999-18

This 45RFE-HD2-A Reprogramming Kit fits 1999 to 2018 Chrysler, Dodge, RAM, and Jeep vehicles equipped with 45RFE, 545RFE, 65RFE, 66RFE and 68RFE often have rough lock-up apply, lock-up slide bump apply, TCC slip codes, excessive transmission cooler pressure, converter drain-back as well as soft shifts in performance applications.

More often than not, this transmission will come in with the TC limit valve bore in the pump that is completely wiped out. It wears out so far that it appears the pump will need replacing.  This RFE Reprogramming Kit comes with new, innovative drop-in TC limit parts that will restore TC limit system function in both the early and the late design pumps regardless of the amount of bore wear.

This TransGo Reprogramming Kit includes parts, as well as technical information to address the above issues. It will also make the shifts quicker (transition time from release of present gear to apply of next gear).
