Sticking of bypass components, spring relaxation, or poor ball seat in Ford 4R100 and E4OD units will allow the bypass to open at lower cracking pressure. This reduces TCC (Torque Converter Clutch) apply pressure, cooler flow at the overdrive section, and radiator flow responsible for heat transfer. Sonnax automatic transmission cooler bypass valve kits allow the bypass valve assembly to be rebuilt, salvaging the OE fittings and maintaining cracking pressure at 70 to 75 psi. Features: * Hardened steel T-valve provides secure check ball seat and adequate bypass flow * New spring cracks open at 70 to 75 psi to provide lube if cooler is blocked or restricted * Hardened alloy steel check ball resists damage * Seven new O-rings provide positive seal for cooler circuit * Drop-in Zip Valve parts install quickly and easily Contents: * T-valve * Spring * Check ball * O-rings -- One small -- Two medium -- Two large -- Two extra-large

Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking

TCI Maximizer rebuild kits are ideally suited for off-road, towing, and other severe-duty applications. Each kit contains gaskets, seals, new premium-quality frictions, steels, a high-volume filter, and a drain plug. Also included are valve body recalibration modifications, which provide crisper shifts without the harsh feel found in kits designed for racing. Durability is improved because less heat is generated per shift than is associated with the OEM shift characteristics. TCI Maximizer rebuild kits also increase the torque capacity of the transmission to make towing or off-roading a breeze.
