- 3-4 Flare
- 4-5-6 Slip
- Erratic shift timing
- OD clutch burned
- OD clutch distress
- Overheated fluid
- Pressure control out-of-range codes
Overdrive pressure control valve bore wear allows critical pressure loss that prevents proper hydraulic control of OD clutches.
Recover hydraulic control and renew shift performance by reconditioning the bore and installing Sonnax oversized overdrive pressure control valve kit.
Oversized Overdrive Pressure Control Valve Kit
Overdrive clutches in listed Hyundai/Kia transmissions are applied in fourth, fifth and sixth gears in conjunction with other clutch packs. As the overdrive pressure control valve oscillates and strokes over time, bore deterioration results, which prevents proper hydraulic control of the OD clutch pack. This can cause flares, slipping, erratic clutch apply timing, ratio codes, and burnt overdrive clutches.
Reconditioning the bore and installing Sonnax oversized overdrive pressure control valve kit 102741-18K returns normal shift operation by restoring hydraulic integrity to the OD circuit.
- Annular grooves help center valve in bore to reduce future side-load wear
- New spring matches OE calibration
- Hardcoat anodized aluminum valve combats premature wear
