Transmission Circuit and Wiring Problems

Transmission connectors and harnesses take a beating. They can become stretched from worn motor and transmission mounts. They become frayed and damaged from rubbing up against other components and burned if too close to exhaust. This damage and wear create circuit problems like opens, shorts and grounds. Any of these problems can be intermittent meaning that the occur one minute and are gone the next. These are reoccurring problems that can be difficult to diagnose. Inspect the wiring and wiring harness when a code or an electrical problem occurs in an electronic automatic transmission.
