Subaru 5EAT

Tool Required

Symptoms:

• Delayed Forward
• Harsh Reverse
• Erratic line pressure
• 2-3 Harsh
• Low converter & lube flow
• Burnt clutches
• Excess clutch apply pressure
• Delayed Reverse
• Reverse slip

Cause:
OE boost sleeve and pressure regulator bore deterioration allows pressure loss that leads to driveability concerns.

Correction:
Recover hydraulic control and renew transmission performance by reconditioning the bore and installing Sonnax oversized pressure regulator and boost valve kit.

These transmissions may exhibit insufficient line rise, resulting in delayed engagement, slipping in Reverse, poor shift quality, erratic line pressure and burnt clutches. These troubles can often be caused by wear in the OE pressure regulator valve bore and/or boost sleeve, which allows the pressure escape that provokes driveability concerns. Reconditioning the bore and installing this Sonnax oversized pressure regulator and boost valve kit eliminates pressure loss and revives line rise and shift quality in all ranges. Hardcoat anodized aluminum pressure regulator valve combats premature wear.

Note:
Replaces both early- and late-style pressure regulators.
