Symptoms:

  • Harsh Reverse
  • Delayed engagement
  • High line pressure
  • Low line pressure
  • No line rise
  • Converter concerns

Cause:

Constant oscillation of the main regulator valve and/or the boost regulator valve in their bores creates wear, which can result in oil pressure loss or cross leaks and valve malfunction.

Correction:

Sonnax now offers an oversized valve kit for both the main regulator valve and boost regulator valve to restore proper clearance to the bore and prevent oil loss.

Warning:

Tool kit F-119940-TL73 is no longer in production but may be available from distributor inventory.

View Instructions Find a Distributor

In listed VW/Audi units, wear at the inboard end of the boost regulator bore can reduce the ability of EPC/TV pressure to stroke this valve open. Full boost exiting this valve combines forces with the main regulator spring, increasing line pressure. Sonnax oversized boost regulator valve kit 119940-07K allows the bore to be refurbished and restore proper pressure control.

  • Oversized hardcoat anodized valves are manufactured to extremely tight tolerances and resist wear
  • O-Ringed end plug positively seals the bore and prevents regulated boost line pressure from exhausting
  • A new spring is included to work with the oversized valve and re-establish OE regulated pressure specifications
  • A replacement ratcheting end plug is included as the OE one often breaks
