Symptoms:

  • 2-3 Shift concerns
  • 4-5 Concerns
  • Delayed Reverse
  • Gear ratio & solenoid codes
  • K3 Clutch burned
  • Slipping gears

Cause:

Oscillation of the K3 clutch control valve causes bore wear that prevents proper hydraulic actuation of K3 clutches.

Correction:

Ream the valve bore and install the Sonnax improved valve and sleeve assembly and calibrated spring.

K3 clutches in Aisin AW TF-60SN (VW/Audi 09G, 09K, 09M) and Mini 6F21WA units are applied in 3rd, 5th and Reverse gears in conjunction with other clutch packs. As the K3 clutch control valve oscillates and strokes over time, bore deterioration results, which prevents proper hydraulic control of the K3 clutch pack. This can cause flares, slipping, erratic clutch apply timing, ratio codes, bind-ups, and burnt K3 clutches. Reconditioning the bore and installing Sonnax oversized K3 clutch control valve kit 15741-08K restores normal shift operation by re-establishing the hydraulic integrity of the K3 circuit.

  • Highly wear-resistant sleeve provides additional support to the control valve
  • Hardcoat anodized aluminum
  • Has more sealing contact with bore than OE to minimize leakage
  • New spring maintains OE operating pressures
  • Valve
  • Sleeve
  • Spring
