Description
C6 Boost Valve Kit, Sonnax 36946-03K.
Heavy-duty vehicles with Ford C6 transmissions often display poor line rise, which results in erratic shift timing, Reverse shudder or direct clutch failure. This can be caused by excess wear at the inside diameter of the boost sleeve. This wear allows oil to leak past the boost valve to exhaust, resulting in poor or no line rise. Recover the hydraulic integrity of the boost circuit and restore proper line rise by installing Sonnax diesel-ratio boost valve kit 36946-03K.
- Diesel-ratio kit restores OE boost pressure
- Sleeve manufactured from highly wear-resistant aluminum
- Hardcoat anodized aluminum valve combats premature wear
- Drop-in Zip Valve™ parts install quickly and easily
A number of boost valve kits are available for this unit:
- Normal line pressure boost (gas ratio): Kits 36946-01K, 36946-04K and 36941-01K.
- Increased line pressure boost (diesel ratio): Kits 36946-02K and 36946-03K are recommended for all heavy-duty applications.
