Symptoms:

  • No line rise
  • No 2-3
  • 3-4 Late

  • Loss of gear

Cause:

Constant oscillation of the solenoid regulator valve creates bore wear. This wear can result in oil pressure loss and reduce solenoid feed pressure and balance line pressure at the main regulator valve.

Correction:

Sonnax offers an oversized valve for the solenoid regulator valve. This allows the valve bore to be refurbished to restore solenoid feed oil pressure.
