Symptoms:

  • Chatter on acceleration
  • Damaged valve body casting
  • High line pressure
  • Low line pressure
  • Pulley breakage
  • Slips in Forward & Reverse

Cause:

Excess bore/valve wear allows circuits to cross-leak which in most instances will exhaust critical oil pressure and volume back to the sump. Wear at the inboard valve spools can contribute to excess primary pulley oil pressure. Wear at the outboard spool can result in low primary pulley oil pressure.

Correction:

Restore proper hydraulic operation by reconditioning the bore and installing Sonnax's oversized primary pulley regulator valve kit.
