THM 4L60-E Automatic Transmission Repair Manual PDF Free Download. This booklet contains general description and the procedures necessary to repair, overhaul, or service the new THM 4L60-E electronic automatic overdrive transmission. The 4L60-E is a hilly automatic rear wheel drive transmission. This unit is basically a THM 700-R4 with electronic controls added to the valve body. The shift pattern is controlled electronically with 2 shift solenoids that recieve a ground signal from the Powertrain Control Module (PCM). The PCM will vary shift points, as it is constantly interpreting numerous electronic signals from various operational sensors located on the vehicle.

The PCM also controls the apply and release of the Torque Converter Clutch (TCC). This transmission also recieved another PWM solenoid in 1995 to control TCC apply feel. Line pressure and shift feel are controlled electronically with a Pressure Control Solenoid (PCS), located on the valve body and dependent on TPS and VSS signals.

Note: There have been many engineering changes in this transaxle since its introduction in 1993. ATSG also has available an “Update Handbook ” which includes the many changes and is required along with this man ualfor a proper o verhaul or repair.
