Torque Converter Assembly Removal

CAUTIONThe torque converter weighs approximately 65 lbs. Personal injury may result if you lift the torque converter improperly.
  1. Remove the torque converter assembly (1).
  2. Remove the turbine shaft O-ring seal (520).

Torque Signal Regulator Valve (321)

Regulates line pressure into the torque signal fluid circuit. This regulation is controlled by filtered actuator feed fluid pressure from the PC solenoid valve.

Pressure Regulator Valve (313) (Torque Converter/Cooler and Lube Circuits)

Line pressure at the valve enters the converter feed circuit which is then routed to the TCC control valve.

Torque Converter Clutch

With the TCC control PWM solenoid OFF the converter clutch is released in Second gear. Under normal operating conditions the TCC is released in Second gear. However, TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Second Gear.

With the TCC control PWM solenoid OFF the converter clutch is released in Second gear. Under normal operating conditions the TCC is released in Second gear. However, TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Second Gear.

Overdrive Range, Third Gear - Torque Converter Clutch Not Applied (Without Touch Activated Power)

As the speed of the vehicle increases, the powertrain control module (PCM) receives input signals from various engine and transmission sensors. The PCM uses this data to energize the 2-3 shift solenoid (SS) valve in order to shift the transmission into third gear at the appropriate time.

TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Third Gear.

Overdrive Range, Third Gear - Torque Converter Clutch Not Applied (With Touch Activated Power)

As the speed of the vehicle increases, the powertrain control module (PCM) receives input signals from various engine and transmission sensors. The PCM uses this data to energize the 2-3 shift solenoid (SS) valve in order to shift the transmission into third gear at the appropriate time.

TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Third Gear.

Overdrive Range, Fourth Gear - Torque Converter Clutch Not Applied (Without Touch Activated Power)

As the speed of the vehicle continues to increase, the powertrain control module (PCM) monitors the input signals from various engine and transmission sensors. The PCM uses this data to energize the 1-2, 3-4 shift solenoid (SS) valve in order to shift the transmission into fourth gear at the appropriate time.

TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Fourth Gear.

TCC apply could vary depending on vehicle application and may be calibrated to apply in Overdrive Range - Fourth Gear.

Overdrive Range, Fourth Gear - Torque Converter Clutch Applied (Without Touch Activated Power)

The torque converter clutch applies during third or fourth gear operation after the powertrain control module (PCM) receives the appropriate input signals to energize the TCC control (PWM) solenoid. To apply the torque converter clutch, the following changes take place in the electrical and hydraulic systems

TCC apply fluid is routed to the torque converter clutch at the same time TCC release fluid exhausts from the torque converter clutch. TCC apply fluid pressure applies the TCC.

To apply the torque converter clutch, the following changes take place in the electrical and hydraulic systems

TCC apply fluid is routed to the torque converter clutch at the same time TCC release fluid exhausts from the torque converter clutch. TCC apply fluid pressure applies the TCC.

Overdrive Range, 4-3 Downshift - Torque Converter Clutch Not Applied (Without Touch Activated Power)

When the transmission is operating in Fourth gear, a 4-3 downshift will occur if there is a significant change (increase) in the throttle position or if the load on the engine is increased. When the 4-3 downshift occurs, the torque converter clutch will release prior to the shift occurring which results in the following changes in the hydraulic system

Overdrive Range, 4-3 Downshift - Torque Converter Clutch Not Applied (With Touch Activated Power)

When the transmission is operating in Fourth gear, a 4-3 downshift will occur if there is a significant change (increase) in the throttle position or if the load on the engine is increased. When the 4-3 downshift occurs, the torque converter clutch will release prior to the shift occurring which results in the following changes in the hydraulic system

The PCM will release the TCC before downshifting into Manual Second. The TCC will not re-apply in Second gear under normal operating conditions.
