Symptoms:

  • High line pressure
  • Low line pressure
  • Poor shift quality
  • Burnt clutches

Cause:

The constant oscillation of the pressure regulator valve results in bore wear, which allows valuable line pressure leakage which can lead to various shift complaints and burnt clutches.

Correction:

Sonnax oversized pressure regulator valve kit eliminates oil leakage and restores proper line pressure control, improving shifts and reducing clutch distress.

You need this if...

Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
