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.

Noticing some forward slip and/or delayed engagement with your GM automatic transmission? Sonnax accumulator pistons are direct replacements for OE plastic pistons and restore sealing integrity at the pin bore. The aforementioned issues, as well as burnt clutches and bands can be caused by loss of fluid. Deterioration at older aluminum piston pin bores due to repeated reciprocation and/or cracks in plastic accumulator pistons may be the cause. Avoid a costly valve body replacement by ordering a Sonnax accumulator piston.
