Overdrive is used when cruising at highway speeds to improve gas mileage. What you may be feeling instead is the car going into passing gear when you hit the accelerator very hard. This is not the same as overdrive.
something is wrong in the transmission. It will have to be diagnosed. You probably have a bad shift solenoid in the tranny.
I would say that it's a electrical switch problem and nothing wrong with the tranny itself.
coolant temp sensor
It sounds like a transmission problem rather than an engine problem.
Depends on year of truck if it doesn't have over drive and even then maybe there is a vacuum line going to shift module on trans mission check and see and if so see if it came off at transmission and if not trace it up to motor
If this is an automatic transmission, which I am assuming it is it will not work the same as a standard. Only drive it in overdrive or 1st gear.
No, something is wrong.
Throttle body issue.
If the ABS light is on, it quite possible that the computer will not allow the transmission to shift into OD until the problem is repaired. Go to a good repair shop or your nearest dealer.
could be one of three things either choke is not working needle and seat are worn and fuel is leking or accelerator pump is worn and not pumping fuel
Take it in. There is either a problem with your transmission or with the overdrive switch itself. Overdrive switch should be a lot cheaper to fix. I'm assuming the light not only goes on, but the overdrive physically turns off as well when the light is on.
It means you have an electronic transmission control problem. Quite possibly a shift solenoid in the transmission. It will be impossible to determine a fix until the system is scanned and diagnosed to find out what is wrong. It could be your vehicle speed sensor.
