Cause:
Continuous oscillation of the pressure regulator valve causes valve body bore wear, resulting in line pressure irregularities and valve instability.
Correction:
Sonnax oversized pressure regulator valve kit combines a sleeved balance spool to eliminate the wear preventing proper valve stroke, and a modified pressure regulator valve with lengthened spools to increase sealing contact and provide greater stability.
Continuous oscillation of the pressure regulator valve in Hyundai/Kia A4CF1, A4CF2 transmissions cause valve body bore wear, resulting in line pressure irregularities and valve instability. Sonnax oversized pressure regulator valve kit fixes these issues by combining a sleeved balance spool to eliminate the wear preventing proper valve stroke, and a modified pressure regulator valve with lengthened spools to increase sealing contact and provide greater stability.
The balance sleeve and valve assembly eliminates wear to allow proper stroking of the valve, has lengthened bore engagement for greater sealing integrity, and is made from wear-resistant materials for durability
The pressure regulator valve has lengthened spools at critical locations to increase sealing contact for better pressure regulation and valve stability
A new spring is included to restore OE pressure specifications and work with the lengthened pressure regulator valve
