How to Service and Repair the Shift Solenoid for the 2-3 Gear Transition on Buick Terraza?

The first step to replace the 2-3 Shift Solenoid valve requires the removal of the case side cover and disconnection of the transaxle wiring harness. A small screwdriver or pick helps remove the 2-3 Shift Solenoid valve retainer (314C) from control Valve Body 301 and allows the extraction of 2-3 Shift Solenoid 315b. Undo the o-ring seal (316) from the 2-3 Shift Solenoid valve (315B) only if it becomes damaged.
