Product Description
Fits: 4R100, E4OD
Fits '96-later, 2-spool valve
- Tooling:
- F-36947-TL14
- VB-FIX
Sonnax offers 36947-14 and [36948-22], solenoid regulator valves and their tool kits to salvage worn valve bodies and restore proper solenoid regulator valve (SRV) circuit function in both early- and late-style Ford E4OD and 4R100 units. Bore wear at the SRV reduces oil supplied to the shift, TCC and coast clutch solenoids. This regulated pressure also feeds the intermediate or center support area. The '96-later valve bodies incorporated a two-spool anodized aluminum valve that is prone to flaking of the anodized layer, causing premature wear of valve and bore. The '95-earlier have a three-spool steel valve that wears the bore, resulting in excess clearance when hot.
- Hardcoat anodized aluminum valve combats premature wear
- Annular grooves center the valve hydraulically to prevent wear

Warning
Required tool kit F-36947-TL14 is no longer in production. Check with your distributor for availability.
Symptoms
- 2nd Gear starts
- 3rd Gear starts
- TCC cycling
- TCC slip
- Reduced lube oil from the center support
Cause
All solenoid regulator valve (SRV) solenoid feed oil and intermediate lube oil passes through the solenoid regulator valve. When the bore wears, critical solenoid feed oil and intermediate lube fluid leaks to exhaust causing shift related problems and loss of lube.
Correction
Sonnax oversized solenoid regulator valve restores SRV pressure.
