Symptoms:
  • 2-3 Flare
  • B5 Clutch distress
  • Engine stall on engagement

Correction:

The tightly toleranced, drop-in replacement Sonnax valve and sleeve assembly restores proper hydraulic clearances and uses upgraded materials to prevent wear.

  • Sleeve is manufactured from highly wear-resistant billet aluminum.
  • Valve is made from hard-coat anodized aluminum to prevent wear.
  • Salvages costly cores with minimal labor.
  • Eliminates the need for expensive OE valve bodies.

You need this if...

A vacuum test of the sleeve assembly (while in the bore at the outboard solenoid modulator feed port indicated) gives less than 18" of vacuum, or if a Wet Air Test at the same location results in leakage at the neighboring exhaust port on the opposite side of the casting
