OVERSIZE SOLENOID REGULATOR VALVE KIT

Symptoms:

  • Wrong gear starts
  • Solenoid performance codes
  • TCC codes & concerns
  • Harsh shifts
  • Soft shifts
  • Burnt TCC apply components
  • Burnt clutches

Cause:
Bore wear at the solenoid regulator valve allows pressure loss that causes engagement issues and driveability concerns.

Correction:
Recover hydraulic control and renew shift performance by reconditioning the bore and installing Sonnax oversized solenoid regulator valve kit.


Ford 4R44E, 4R55E, 5R44E and 5R55E units often suffer shift abnormalities caused by excess wear in the solenoid regulator valve bore. This wear allows fluid loss which 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 the Sonnax oversized solenoid regulator valve kit re-establishes correct clearance for revived shift control in all ranges.

  • Hardcoat anodized aluminum valve combats premature wear
  • Spring calibrated to help restore OE function
  • Annular groove helps center valve in bore to reduce future side-load wear
