Why cant you turn overdrive off in your 2002 escape?

In a 2002 Ford Escape, the inability to turn off overdrive could be due to a malfunction in the transmission or the overdrive button itself. If the button is stuck or the wiring is damaged, it may not function properly. Additionally, the vehicle's computer system might not be registering the command to disable overdrive. If you're experiencing this issue, it's advisable to consult a mechanic for a thorough diagnosis.
