When to disengage overdrive?

You should disengage overdrive when driving in conditions that require more power, such as going uphill, towing heavy loads, or navigating through stop-and-go traffic. Disengaging overdrive allows the engine to operate at a higher RPM, providing better acceleration and control. Additionally, it's advisable to turn off overdrive in situations where frequent braking and acceleration are needed, as this can help improve responsiveness and reduce strain on the transmission.
