TCC Signal Damper Piston Kit for 10R60/80and 10L80/90 (Gen. 1)
TCC SIGNAL DAMPER PISTON KIT (10R/10LG1)
Symptoms:
Lube failures
TCC apply & release concerns
Overheated fluid
Overheated converter
Delayed engagement
Cause:
Bore and/or piston wear in the signal damper can allow TCC signal oil pressure to be exhausted, preventing correct TCC apply.
Correction:
Sonnax drop-in TCC signal damper piston kit corrects circuit pressure variation by replacing the worn OE damper without the need of modifying the valve body.
TCC signal dampers are used in Ford 10R60, 10R80 and GM Gen. 1 10L80/90 transmissions to dampen or smooth out the signal fluid pressure applied from the TCC solenoid before being routed to the TCC control valve. This damper piston helps provide a smooth operation of the converter by removing the pressure spikes. When the bore and/or piston wears out, it cannot effectively dampen the variation in pressure. This can result in lube failures, TCC apply and release concerns, overheated fluid or converter and delayed engagement. Replacing the worn out damper can require replacing the entire control valve body.
This Sonnax TCC signal damper piston kit allows long-lasting and quick repair of the lower valve body casting without reaming. The O-ring provides a positive seal against critical pressure loss even in worn bores.
