Vehicles with Ford AX4N transmissions often have converter clutch apply and release problems which are most affected by high operating temperatures. These complaints can be caused by severe wear of the valve body bore at the bypass clutch control valve, allowing regulated converter charge oil leakage. This oil is fed to the lube circuits, cooler and to help maintain the TCC in the release position. If the valve bore is worn, converter feed and lube oil will exhaust and MCCC solenoid control is limited. Sonnax offers standard bypass clutch control sleeves and plungers in OE sizes .486" 96206-03K or .496" 96206-13K to replace a worn plunger and sleeve when the bypass clutch control valve is not worn and can be reused. However, when the valve is too worn, Sonnax offers oversized bypass converter clutch valve kit 96206-05K. This kit also includes a bypass clutch control sleeve and plunger assembly matched to the oversized bypass clutch control valve.

• TCC solenoid oil and CT oil spools have annular grooves to help center the valves in the bore
• Hardcoat anodized aluminum valve combats premature wear
• Kit includes a replacement bypass clutch control sleeve and plunger kit, which is often severely worn, so that valve ratios remain consistent
• A bore sizing tool is included in the reamer kit to ensure proper fit and bore integrity after reaming
