Q: How to replace the 2-3 Shift Solenoid Valve on Buick Terraza?
A: The first step to replace the 2-3 Shift Solenoid valve requires removal of the case side cover and disconnecting of the transaxle wiring harness. A small screwdriver or pick helps you remove the 2-3 Shift Solenoid valve retainer (314C) from the control Valve Body (301). After that, proceed with taking out the 2-3 Shift Solenoid (315B). Damaged o-ring seal (316) needs to be eliminated from the 2-3 Shift Solenoid valve (315B). When performing the installation place an undamaged o-ring seal (316) onto the 2-3 Shift Solenoid valve (315B) if necessary before installing the 2-3 Shift Solenoid (315B) while securing the 2-3 Shift Solenoid valve retainer (314C) into the control Valve Body (301). Reconnect the wiring harness while finishing by placing back the case side cover.
Q: How to replace the 2-3 shift solenoid (315B) and reset the transmission adaptive pressure (TAP) values on Buick Rendezvous?
A: The first step for 2-3 Shift Solenoid (315B) replacement includes disassembling the case side cover along with transaxle wiring harness detachment. Next, remove the 2-3 Shift Solenoid (315B). The replacement process begins by installing the 2-3 Shift Solenoid (315B) before reattaching the transaxle wiring harness and putting back the case side cover. Vehicle performance might be affected by this process because the transmission adaptive pressure (TAP) values need to be reset using a scan tool to delete all learned values from all cells. After erasing these values the ecm, pcm or tcm has to relearn tap values.
