Sonnax Accumulator Pistons
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.

Sonnax Automatic Transmission Clutch Steels
Upgrade your transmission's clutch pack with Sonnax automatic transmission clutch steels. These premium-quality steel parts give you the best combination of coefficient of friction and performance. Sonnax offers severe-duty clutch steels for use in a variety of automatic transmissions—including racing applications. These steels are available with up to double the number of external teeth as OE. With more teeth engaged, wear should be reduced dramatically. Anti-drag tabs create the maximum clearance between the friction and steel when the clutch is disengaged. Turbulator holes reduce parasitic drag. Combining anti-drag tabs and turbulator holes significantly reduces the heat generated when the clutch freewheels.
