Torque Converter Assembly Removal
| CAUTION | The torque converter weighs approximately 65 lbs. Personal injury may result if you lift the torque converter improperly. |
Scheme 632
Remove the torque converter.
Scheme 633
Rotate the transmission so that the converter housing is up. Allow the transmission fluid to drain from the case extension.

- Inspect the torque converter and replace if any of the following conditions exist: Evidence of damage to the pump assembly. Metal particles are found after flushing the cooler and cooler lines. External leaks in the hub area. Converter pilot is broken, damaged or poor fit into the crankshaft. Converter hub is scored or damaged. Internal damage to the stator. Contamination from engine coolant. Excessive end play.
- Install the J 35138 , the J 26900-13 and the J 8001 or J 39195 to be used with the 300 mm torque converter. Specification: The end play for a 245 mm torque converter should be 0-0.38 mm (0-0.015 in). The end play for a 298 mm torque converter should be 0.1-0.48 mm (0.004-0.019 in). The end play for a 258 mm and 300 mm torque converter should be 0.1-0.5 mm (0.004-0.020 in).
- Remove the tools.
Torque Converter Clutch PWM Solenoid and Regulator Apply and Isolator Valve
AFL fluid is routed to the TCC PWM solenoid valve, in Park the PCM has the duty cycle turned OFF. This prevents AFL fluid from entering the converter clutch signal fluid circuit. Regulated line pressure is routed to the regulator apply valve, which is open with CC signal circuit empty, and blocks line pressure from entering the regulated apply circuit. Any fluid in the regulated apply circuit will exhaust at the regulated apply valve.
Torque Converter
Release fluid pressure unseats the TCC apply checkball (#9), keeps the pressure plate released from the converter cover and fills the converter with fluid. Fluid exits the converter between the converter hub and the stator shaft in the apply fluid circuit.
Torque Converter Clutch PWM Solenoid Valve
In first gear, at approximately 6 mph, the PCM operates the TCC PWM solenoid valve at approximately a 90 percent duty cycle. This opens the AFL fluid circuit, to fill the converter clutch signal fluid circuit through the #9 orifice, and flows to the isolator valve. The CC signal fluid pressure, acting on the isolator valve, will move the regulated apply valve towards the closed position. Regulated line pressure is now routed into the regulated apply circuit, and flows to the closed converter clutch valve, and is blocked from entering the converter clutch apply circuit. Regulated apply fluid is routed through the #8 orifice to the front of the regulated apply valve, and regulates the line pressure entering the regulated apply circuit, in response to the CC signal fluid acting on the isolator valve.

Overdrive Range, Fourth Gear - Torque Converter Clutch (TCC) Applied
At higher vehicle speeds, the Hydra-matic 4L60-E transmission uses an overdrive gear ratio (fourth gear) in order to increase fuel economy and in order to maximize engine performance. When vehicle operating conditions are appropriate, the PCM energizes the 1-2 shift solenoid valve to shift the transmission into fourth gear.
Release fluid from behind the pressure plate exhausts through the end of the turbine shaft. Apply fluid pressure is routed between the converter hub and stator shaft where it enters the torque converter. This fluid applies the converter clutch against the converter cover and keeps the converter filled with fluid.
Torque Converter Clutch and Torque Converter Clutch PWM Solenoid Valve
The PCM de-energizes the TCC solenoid valve and operates the duty cycle of the TCC PWM solenoid valve to release the converter clutch prior to downshifting, (assuming the converter clutch is applied in Overdrive Range-Fourth Gear when Manual Third is selected). The PCM will re-apply the converter clutch in Manual Third-Third Gear when proper driving conditions have been met.
Torque Converter Clutch
The converter clutch is released prior to downshifting into manual second-second gear. Under normal operating conditions, the TCC will not apply in second gear.
