The listed Nissan/Jatco transmissions can have complaints associated with a worn plunger valve and sleeve which includes jerking on coastdown, harsh engagement, 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 lockup control plunger valve kit 113741-11K can restore correct clearances and maintain proper hydraulic control of the lockup clutch.

Hardcoat anodized aluminum valve combats premature wear
Sonnax sleeve manufactured of highly wear-resistant aluminum alloy
Direct replacement, requires no tools and minimal bore preparation prior to assembly
