Troubleshooting RFE overdrive clutch failure: Three key areas to check

Fighting overdrive failure in Chrysler RFE transmissions can be a frustrating task. You build the unit, and a week later, it’s back with the overdrive clutches burned up again. It happens with every one of them, from the 45RFE, 545RFE and 65RFE to the 66RFE and 68RFE. You have replaced the valve body and double-checked

Diagnosing Chrysler transmission max line pressure and P0933, P0869, P1745 codes

This article applies to Chrysler RFE, RLE and TES transmissions that utilize pressure control solenoids (PCS) for line pressure control. The subject is a rather common electrical fault that may occur on the PCS line pressure solenoid circuit, which results in max line pressure. Diagnosis and correction of a max line pressure condition may become

Alto introduces new Chrysler RFE bushing kits

Alto has introduced two new bushing kits for Chrysler and Dodge transmissions. Transmissions covered include 45RFE, 545RFE, 65RFE, 66RFE and 68RFE.

How to easily check endplays in Chrysler RFE transmissions

When building a reliable transmission for everyday drivers, it’s tempting to skip checking gear set endplay because of the factory tool cost. Often, I hear: “I feel movement, so at least I know it is not going to bind up;” or “This play feels good to the touch, so it is okay;” or “It’s not
