Oversize C3 Clutch Control Valve Kit

OVERSIZE C3 CLUTCH CONTROL VALVE KIT

Symptoms:

  • 2-3 Shift concerns
  • 4-5 Concerns
  • Delayed Reverse
  • C3 Clutch burned
  • Slips & flares
  • Pressure control out-of-range codes

Cause:
Oscillation of the C3 clutch control valve causes bore wear, allowing critical pressure escape and preventing proper actuation of C3 clutches.

Correction:
Recover hydraulic control and renew shift performance by reconditioning bore and installing Sonnax oversized C3 clutch control valve kit.


C3 clutches in Aisin AW TF-80SC and TF-81SC transmissions are applied in 3rd, 5th and Reverse Gears in conjunction with other clutch packs. As the C3 clutch control valve oscillates and strokes over time, bore deterioration results, which prevents proper hydraulic control of the C3 clutch pack. This can cause flares, slipping, erratic clutch apply timing, ratio codes, bind-ups, and burnt C3 clutches. Reconditioning the bore and installing Sonnax oversized C3 clutch control valve kit restores normal shift operation and feel by re-establishing the hydraulic integrity of the C3 circuit.
