Symptoms:

  • Burnt clutches
  • Pressure loss
  • Poor shift quality

Cause:

Wear of the 2-3-4-6-8 (S4) clutch control valve and bore can allow clutch apply fluid pressure to leak, resulting in pressure loss, a burnt clutch and poor shift quality.

Correction:

Restore proper hydraulic control and renew clutch apply fluid pressure performance by replacing worn OE parts with Sonnax drop-in S4 clutch control valve kit.
