Symptoms:

  • Engine stall on engagement
  • Increased RPM during acceleration
  • No lockup
  • Overheated fluid
  • Poor fuel economy
  • Poor lube oil control
  • Poor performance
  • Ratio codes

Cause:

The OE lockup control plunger valve and sleeve wear allowing hydraulic pressure to escape. The reduced or absent pressure allows pressure deviations preventing proper control of TC and lube functions.

Correction:

Restore proper hydraulic control by refurbishing the bore and replacing worn OE lockup control plunger valve and sleeve with Sonnax components.

Jatco/Nissan JF015E (RE0F11A) transmissions can have complaints associated with a worn plunger valve and sleeve which includes increased RPM during acceleration, no lockup and engine stall on engagement. This is due to the wear at the inside of the lockup control plunger valve sleeve allowing oil to escape, which affects the timing and quality of the lockup clutch apply and release action. Installing Sonnax torque converter lube regulator plunger valve kit 33741F-07K can restore correct clearances and maintain proper hydraulic control of the lockup clutch.
