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, SS1, SS2, SS3.
- Powertrain control module.
