Symptoms:

  • Low line pressure
  • High line pressure
  • Clutch failure
  • Erratic line pressure

Cause:

Excess valve and bore clearance due to oscillating valve bore wear allows critical pressure to exhaust, causing high, low or unstable line pressure depending on the location of the wear.

Correction:

Sonnax oversized pressure regulator valve kit restores the correct valve/bore clearances and line pressure control.

Wear can occur in Chrysler 948TE, Honda/Acura, 9-speed and ZF9HP48 units in the pressure regulator bores. This wear allows critical oil loss and prevents proper line pressure regulation. Incorrect pressure regulation can result in instability, cooler and lube flow restrictions, bad shifts and damaged clutches. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 85740-15K restores correct pressure regulation.
