Product Description
6R140 Oversized Forward Clutch Latch Valve Kit
Sonnax Part Number: 126740-06K
TOOLING REQUIRED
- F-126740-TL6
- VB-FIX
The Ford 6R140 Forward clutch latch valve provides feedback pressure to the Forward clutch regulator valve, balancing the regulator to assist with apply and release of the Forward clutch. Excess wear at this bore causes leakage that affects Forward clutch timing and feel, resulting in delayed engagement, harsh shifts, burnt Forward clutches, ratio codes and overheated fluid.
Reconditioning the bore and installing Sonnax oversized Forward clutch latch valve kit 126740-06K restores normal shift operation and Forward clutch control by reviving the hydraulic integrity of this circuit.
