Pressure reducing valve bore wear causes erratic supply pressure to control solenoids.
Recover hydraulic control and renew shift performance by reconditioning the bore and installing Sonnax oversized pressure reducing valve.
Oversized Pressure Reducing Valve
Fits two locations.
Listed Hyundai/Kia transmissions often suffer shift abnormalities caused by excess wear in the pressure reducing valve bores. This wear prevents proper regulation of oil pressure supplied to control solenoids, resulting in harsh or soft shifts, solenoid codes, wrong gear starts, TCC apply issues, and clutch failure. Reconditioning the bore and installing Sonnax oversized pressure reducing valve 102741-07 re-establishes the hydraulic integrity of this circuit, restoring normal shift operation and feel.
- Hardcoat anodized aluminum valve combats premature wear
- Annular groove helps center valve in bore to reduce future side-load wear
