Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Symptoms:
- Excess TCC slip
- TCC shudder
- TCC codes
- Overheated fluid & TCC lining
- TCC apply & release concerns
- Loss of fuel economy
Cause:
TCC control bore wear allows pressure loss that results in driveability concerns.Correction:
Recover hydraulic control and renew TCC performance by reconditioning the bore and installing Sonnax oversized TCC control and plunger valve kit.40TE, 40TES, 41AE, 41TE, 41TES, 42LE, 42RLE, 62TE
Oversized TCC Control & Plunger Valve Kit
Part No. 92835-33K
For 40 and 41 series transmissions, this kit CANNOT be used in early units that have #33 separator plates. Kit can only be used in later designs that have a #4 retainer clip inthe TCC control valve bore. Kit is compatible with all 42LE, 42RLE and 62TE units.

Common problems associated with listed Chrysler units are high TCC slip, TCC lining degradation, TCC slip codes, converter apply or release concerns and reduced fuel economy. These issues are often caused by excess wear at the TCC control valve bore, which allows critical pressure to escape the circuit. Reconditioning the bore and installing Sonnax oversized TCC control and plunger valve kit 92835-33K restores hydraulic integrity for revived TCC operation.
- Hardcoat anodized aluminum valves combat premature wear
- Annular grooves help center valve in bore to reduce future side-load wear
- Control Sleeve
- Control Plunger
- Control Valve
- Dampener Plunger
