What action should you take if the M1120 transmission range selector flashes the current gear selection while operating the vehicle?

Answer: C — Move to a safe place for maintenance

When the M1120 transmission range selector flashes the current gear selection while the vehicle is in operation, this indicates a potential issue with the transmission system that requires attention. Moving to a safe place for maintenance is essential because it ensures that the driver can assess the problem without risking an unsafe situation on the road. Recognizing that a flashing gear selector can signal a malfunction, it is prudent to prioritize safety and vehicle integrity. Stopping to receive maintenance allows for a thorough inspection of the transmission system to diagnose and resolve the issue, preventing further complications or damage that could occur if the vehicle continues to be driven under these circumstances. While other options may seem like immediate fixes, they do not adequately address the underlying issue indicated by the flashing selector and could potentially lead to more serious problems if not properly diagnosed.
