NOTE:This pinpoint test is intended to diagnose the shift solenoids electrical system only. To prevent replacement of good components, be aware that the following areas may be at fault:
Engine - Performance, cooling, brakes
Electrical - Battery, input sensors, wiring harnesses
Transmission - Internal transmission components, linkages, cooling
This pinpoint test is intended to diagnose the following components:
Transmission wiring harness, 881, 882, VPWR
Powertrain control module
Transmission Internal Harness:
Solenoid Operation Chart:
Shift Solenoid Failure "Always Off"
SS1/SS2 Always Off:
Failed off due to powertrain control module and/or vehicle wiring concerns, shift solenoid (7G484) electrically or hydraulically stuck off.
Shift Solenoid Failure "Always On"
SS1/SS2 "Always On":
Failed on due to powertrain control module and/or vehicle wiring concerns, shift solenoid electrically or hydraulically stuck on.
