4F27E, FN4A-EL, FNR5, FS5A-EL Transmission Sonnax Oversized Pressure Regulator Kit
Ford/Mazda 4F27E, FN4A-EL, FNR5 and FS5A-EL units may exhibit multiple line pressure and converter-related problems due to excess wear in the pressure regulator bore. Wear at the balance spool end allows critical fluid loss, resulting in high line pressure, harsh shifts, and overheating due to reduced cooler/converter/lube flow. Wear at the outboard spool area robs converter feed pressure and lowers line pressure, causing soft shifts and burnt clutches and bands. Reconditioning the bore and installing Sonnax oversized pressure regulator valve kit 46892-01K restores hydraulic integrity for proper line pressure control in all ranges. Hardcoat anodized aluminum valve combats premature wear.
Symptoms:
Clutch & band failures
Harsh shifts
High line pressure
Loss of lube oil
Low converter pressure
Low line pressure
Soft shifts
Cause:
Continuous oscillation of pressure regulator valve results in excess bore wear, causing erratic line pressure and/or restricting converter feed oil.
Correction:
Recover hydraulic control and renew line pressure performance by reconditioning the bore and installing Sonnax oversized pressure regulator valve kit.
