Chevrolet Sonic Repair Manual: 2-6 Clutch Piston Installation (6T40/45/50)

Note:

• Position the 2?E piston air bleed and large slot toward the top of the case.
• DT-47796 seal protector prevents the piston seal lip from damage during installation. Apply a thin coat of ATF to the I.D. of the DT-47796 seal protector to ease installation of the piston.

Caution:

Regulate the air pressure to 276 kPa (40 psi) maximum. High pressure could cause the piston to over travel and damage the piston seals.

Note:

• Place the retainer on the 2-6 clutch spring and align the retainer opening with the largest gap in the case splines toward the bottom of the case. The retainer opening should be supported by a spline tooth of the case.
• Apply shop air to the clutch fluid feed hole in the case to verify proper piston operation.
