Oversized TCC Apply Valve Kit
Part No. 119940-04K

Continuous stroking of the TCC apply valve in VW/Audi 01M, 01N and 01P units can create excessive valve body wear, and allow converter apply pressure to leak to exhaust. This prevents proper engagement of the torque converter clutch, and can result in loss of TCC apply, engine stall, overheating conditions, or a 1582 code. Sonnax oversized TCC apply valve kit 119940-04K allows the valve body to be refurbished, restoring the hydraulic integrity of the circuit.

  • Kit includes an increased ratio TCC boost valve assembly to work with the oversized apply valve. Valve has an identification groove on it. (Do not use the previous OE ratio boost valve.)
  • A replacement TCC apply spring is included, since the original spring is frequently broken

Early versions of this tool kit did not contain bore sizing tool. Customers who already have the reamer and reamer jig are encouraged to order bore sizing tool 119940-BST and complete the bore sizing steps outlined in the instructions on all future kit installations.
