Wear at the piston pin bore surface can result in poor shift quality and burnt clutches and bands. Sonnax pinless accumulator piston kits prevent pin bore leakage. They're also longer to stabilize the piston and prevent piston cocking. They feature dual seals to stabilize and completely seal the bore, and steel balls to plug the existing pin bore. Fluid loss through the piston pin bore will no longer be an issue when you invest in Sonnax piston kits.

Sonnax thrust bearings are replacements for your worn automatic transmission bearings to aid in smooth operation and noise reduction. The bearings act as a guide to help limit any axial movement which can hinder performance. Manufactured to exceed OE specifications for superior quality even under extreme conditions, order the Sonnax thrust bearings best suited for your application.

The Chrysler 46RH/RE, 47RH/RE, 48RE and A727 units used in high performance applications often bend or break the kickdown band strut. To help eliminate these issues, Sonnax offers heavy-duty kickdown band struts—made of solid, heat-treated steel that will not bend or break like other stamped struts. These quality replacements feature an extra-thick cross-section for maximum toughness to withstand the increased intermediate "band" applied forces that are common in high performance applications. Installation is easy: just remove the pan and valve body to expose the bottom of the transmission, loosen the adjusting screw to remove all tension from the band, then remove the original strut and insert your new one with the flat surface facing away from the band. Tighten the adjusting screw to manufacturer specs—and you're good to go!

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
