Overdrive is an essential feature for f350s, and its primary purpose is to reduce engine rpm while increasing speed. It works by shifting into a higher gear than the current one, which is beneficial for fuel efficiency. The overdrive light is a warning sign of a problem in the system.

One possible cause is a faulty solenoid, which could lead to harsh shifting, even in normal driving conditions. Other symptoms include transmission slipping, hesitation, or hard starting. If the overdrive system is faulty, it can affect the f350’s performance, causing the engine to consume more fuel, gradually damaging the transmission.

It’s essential to identify and fix any issues quickly to avoid more significant problems down the road.
