INTRODUCTION THM 4T60-E

This Manual contains the procedures necessary to overhaul, repair or service the THM 4T60-E transaxle. The THM 4T60-E is a fully automatic front wheel drive transaxle that provides park, reverse, neutral and four forward speeds, with 4th gear being overdrive.

The shift pattern is controlled electronically with solenoids that receive a ground signal from the Powertrain Control Module (PCM). The PCM will vary shift points, as it is constantly interpreting numerous electronic signals from the various operational sensors located on the vehicle. The PCM also controls the application of the Torque Converter Clutch and the TCC apply feel electronically with solenoids. Line pressure and shift feel are still controlled by the vacuum modulator system.
