Chevrolet Sonic Repair Manual: Low and Reverse and 1-2-3-4 Clutch Housing, and 1-2-3-4 Clutch Plate Installation (6T40/45/50)

Note:

The longer legs face the bottom of the case and the oil passages face the valve body end of the case.

Note:

• Align the single pair of tabs with the bottom valve body end of the case.
• Ensure the correct waved plate is being installed. The 1??? clutch and low and reverse clutch waved plates are visually similar, however the low and reverse clutch waved plate is thicker.

Note:

Align the single skinny tab with the case spline facing the top of the case.

Warning:

The retainer is under tension. Use care when removing or installing the retainer. Personal injury could result.

Caution:

Use caution during removal or installation of the retainer ring to avoid damage to the case machined surface in the park pawl area. Burrs or raised edges on the case machined surface can cause the park pawl to bind and prohibit it from engaging the park gear.

Note:

• Install the retainer with the taper facing away from the backing plate.
• Align the retainer opening with the largest gap in the case splines toward the bottom of the case.
• Install one end of the retainer into the retainer ring groove. Use DT-28585 snap ring remover and work the retainer into the case groove. Use a screwdriver to hold the retainer away from the case while pushing down on the retainer with DT-28585 snap ring remover.
