RE0F10A, F1CJA, CVT2M, JF011E

Tool Required

Symptoms:

• Jerking on coastdown
• Harsh engagement
• High engine RPM
• No lockup

Cause:
Wear at the inboard lockup control valve spools and bore results in loss of hydraulic control, creating harsh engagement and high engine RPM.

Correction:
Restore proper hydraulic control by refurbishing the bore and installing Sonnax oversized lockup control valve kit.

In Jatco/Nissan JF011E (RE0F10A) units, the lockup control valve operates under the direct command of the lockup control solenoid routed through a select switching valve and is also influenced via apply and release feedback balance passages. A worn bore, valve spool(s) or plunger valve assembly can cause loss of critical pressure to the sump, lube circuit, or directly into apply or release passages resulting in jerking on coastdown, harsh engagement, and high engine RPM due to no lockup.

Reconditioning the bore and installing Sonnax oversized lockup control valve kit restores optimal oil pressure management within the TC clutch apply/release circuits.
