Product Description
Tooling Required
- F-105740-TL18
- VB-FIX
Ford 10R60, 10R80 and GM Gen. 1 10L60/80/90 transmissions utilize a set of four latch valves. The valve’s spring stem and the exhaust gap in the retaining clip make contact with one another, causing raised edges, burrs and other damage on the stem. This can lead to spring entanglement, improper stroking of the valve and significant bore wear, which can result in failures and burnt clutches.
Reconditioning the four bores and installing Sonnax oversized latch valve kit 105740-71K restores normal shift operation. An improved valve design eliminates the risk of retaining clip interference.
- Extended outboard valve spool is 550% longer than OE for improved sealing and stability
- Spring pocket allows valve to avoid exhaust gap in retaining clip for smooth, even contact
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves help center the valve in the bore to reduce future side-load wear
Symptoms
- Burnt clutches
- Lost or damaged component
- Shift concerns associated with circuit pressure loss
- Poor shift quality
Cause
Contact between the OE retaining clips and A, B, C and F latch valves leads to spring entanglement and clutch apply fluid pressure leaks from valve stem and bore wear.
Correction
Recover hydraulic control and prevent future damage by reconditioning the bore and installing Sonnax oversized latch valve kit.
