Why is it necessary to check electrical harness connections after servicing a transmission?

Checking electrical harness connections after servicing a transmission is crucial because it directly relates to the neutral interlock system’s functionality. The neutral interlock system is designed to prevent the vehicle from being started in gear, ensuring safety during operation. Properly connected electrical harnesses are essential for the system to operate as intended.

If the harness connections are loose or improperly connected, it could lead to malfunctioning of the neutral interlock, potentially allowing the vehicle to start in gear, which poses a risk to the operator and others nearby. Therefore, verifying these connections is an important step in maintaining safe operation of the vehicle after any transmission servicing.
