98 windstar wont move

The new guy, be nice.

She won't move in any gear, I see the linkage move and hear clicking. also overdrive lite blinking all the time.

thanks

Overdrive blinking is indicating that there is a failure code.
The code may give you more information on the cause.
One other hint.......when you check the transmission fluid level with the motor not running, you should get a higher fluid level than what you measure with the motor running.

The correct level is at the full indication with the motor warm and running at idle with the vehicle in PARK, on level ground.

If the fluid level is the SAME with the motor running and not running, then the pump is not pumping fluid.

Thank you very much!!!
