Sonnax 113741-11K Lockup Control Plunger Valve Kit for Nissan Jatco CVT Transmissions

The Sonnax 113741-11K lockup control plunger valve kit is a precision-engineered replacement designed to restore proper hydraulic control in Nissan/Jatco CVT transmissions. This kit addresses common wear issues in the lockup control plunger valve and sleeve that cause jerking on coastdown, harsh engagement, no lockup, and engine stall on engagement.

Key Features:

• Hardcoat anodized aluminum valve combats premature wear and extends service life
• Highly wear-resistant aluminum alloy sleeve restores proper clearances
• Direct drop-in replacement requiring no special tools or extensive bore preparation
• Zip Valve™ design allows quick and easy installation
• Restores correct hydraulic pressure control for smooth lockup clutch apply and release

Fits Transmissions:

• Jatco/Nissan JF010E (RE0F09A/RE0F09B)
• Jatco/Nissan JF011E (RE0F10A)
• Jatco/Nissan JF015E (RE0F11A)
• Also fits Mitsubishi F1CJA applications

Solves These Problems:

• Worn OE lockup control plunger valve and sleeve causing hydraulic pressure loss
• Jerking or shuddering during coastdown
• Harsh or delayed engagement
• No lockup clutch engagement
• Engine stall during engagement
• Poor timing and quality of lockup clutch apply and release action

The original equipment lockup control plunger valve and sleeve wear over time, allowing hydraulic pressure to escape. This reduced or absent pressure affects the timing and quality of the lockup clutch operation. The Sonnax 113741-11K valve kit provides a durable, long-lasting solution that restores proper hydraulic control and eliminates these troublesome symptoms.
