TCC Valve 4T60E OEM-size
1996 & earlier with steel valve
The TCC apply valve acts as the switch valve for converter apply and release. The TCC regulator valve (84754-01K and 84754-08K) controls TCC apply pressure. Both the apply valve and the regulator valve can cause slip codes. When the apply valve is worn, it often returns to the unapply position even though the TCC apply solenoid remains energized. Generally the apply valve causes larger changes in slip RPM as the converter cycles from apply to full release. The regulator valve causes a more gradual load and heat-sensitive slip.
Symptoms:
Code 39, 740, 1870
Falls out of lockup when hot
Low cooler flow
Overheated converter
Shudder
Cause:
Wear of the TCC apply valve bore allows leakage of TCC signal oil to exhaust and the apply valve to move into the TCC release position.
Correction:
Wear of the TCC apply valve bore allows leakage of TCC signal oil to exhaust and the apply valve to move into the TCC release position.
