4T65E Transmission Sonnax 3-4 Accumulator Piston

Includes:

1 Piston

Description:

It is common to have poor 3-4 shifts, no 4th gear or a burned 4th clutch in 4T65E units. This can be caused by excessive wear at the 3-4 accumulator piston pin bore, which allows 4th clutch oil to exhaust and can result in harsh 4th, no 4th gear or a burned 4th clutch. Pin bore wear also reduces 3rd clutch pressure during 3-4 shift. The 4th shift quality depends on the condition of the piston and accumulator valves. If the 4th accumulator piston siezes, the 4th shift will be very hard. This piston restores accumulator pressure and eliminates cross leaks.

Features:

Piston is manufactured from high grade billet aluminum to prevent wear
Tight tolerances and surface finish restore proper clearances
Line boost valve is no longer than the OE valve to increase wear surface area
Piston accepts OE or standard replacement D-Ring
