Symptoms:
  • Converter shudder & failure
  • Low TCC apply pressure
  • Low TCC release pressure
  • Overheated fluid & TCC lining
  • TCC codes
  • TCC slip
Cause:

Wear at TCC pressure control plunger valve and sleeve assembly allows critical TCC switch oil to exhaust.

Correction:

Recover hydraulic control and renew TCC performance by installing Sonnax TCC pressure control plunger valve kit.

TCC Pressure Control Plunger Valve Kit

Part No. 102741-01K

  • Valve
  • Sleeve

Complaint:

  • Converter shudder & failure
  • Low TCC apply pressure
  • Low TCC release pressure
  • Overheated fluid & TCC lining
  • TCC codes
  • TCC slip

Cause:

Wear at TCC pressure control plunger valve and sleeve assembly allows critical TCC switch oil to exhaust.


Correction:

Recover hydraulic control and renew TCC performance by installing Sonnax TCC pressure control plunger valve kit.

The TCC pressure control plunger valve and sleeve assembly act to increase pressure to the TCC switch valve. When this control assembly wears, the oil driving the plunger valve and inboard control valve leaks to exhaust, resulting in decreased pressure to switch valve. This pressure deterioration can cause lock-up apply issues, TCC codes, and premature failure of the torque converter. Installation of Sonnax TCC pressure control plunger valve kit 102741-01K will arrest these leaks and reestablish appropriate TCC pressure control.

  • Sleeve is manufactured from highly wear-resistant aluminum
  • Hard-coat anodized aluminum valve combats premature wear
  • Restores proper hydraulic sealing and pressure control

You need this if...

Excessive wear can often be visually identified by shiny patches on the inside diameter of sleeve. Wear can also be determined by vacuum testing, done through feed hole in OE sleeve. Using a small tip (available in Sonnax vacuum test stand kit VACTEST-01K) attached to the line, apply vacuum to one of the feed holes while covering the hole on the opposite side. Be certain OE plunger valve is installed in sleeve while checking.

If sleeve fails to hold at least 18 in-Hg, install this kit.
