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
