Symptoms:

  • Solenoid performance codes
  • Delayed Reverse
  • Gear ratio codes
  • 2-3 Flare

Cause:

Excess wear allows valuable control pressure to exhaust causing multiple shift concerns and performance code related issues.

Correction:

Restore hydraulic control by reconditioning the bores and installing Sonnax oversized linear solenoid output dampener valve kit.

Aisin Seiki AS68RC units often develop 2-3 flaired shifts, gear ratio errors and solenoid performance codes related to pressure switch 1 and 2 due to excess wear in the linear solenoid output dampeners located in the lower valve body casting.

Reconditioning the bores and installing Sonnax oversized linear solenoid output dampener valve kit 99740-04K re-establishes correct clearances for proper hydraulic functions and shift control, salvaging these very expensive and hard-to-find valve bodies.

  • Hardened steel valves combat premature wear
  • Oversized valves recalibrated to meet original OE pressures using the OE dampener springs

Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
