Symptoms:

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

Cause:

Wear of the primary pressure regulator bore minimizes line pressure control. Depending on the severity and location of bore wear, main line pressure may be too high or low, resulting in problems such as pulley breakage or chatter on acceleration.

Correction:

Refurbish the valve bore and install the Sonnax oversized primary pressure regulator valve kit to restore accurate pressure control.
