Q: Overdrive light on 1998 Ford Windstar

The car won't go when u hit the gas but it will kick in eventually like its not shifting into 3rd gear or overdrive battery light comes on won't go off til u shut car off and turn back on but drive so far comes back on brand new battery

Fluid is good May have lost the overdrive solenoid that engages the o.d. because i have a light on and i haven't checked the code yet but i wonder where this solenoid is located or where can i find a picture of the location in the trans.

Was told it could be the torque converter doesn't sound right to me
