*UPDATE* 89 dakota O/D issues
i have a 89 dakota sport with a replaced transmission from a 1990 dakota. (a-500)
i pulled up four codes
34* Speed control vacuum or vent circuit short or open condition detected OR speed control switch input outside accepted range
24** Throttle Position sensor signal outside acceptable range
22** Engine coolant temp sensor signal outside the acceptable range
24** Throttle Position sensor signal outside acceptable range
i fixed the coolant temperature sensor, and the tps sensor.
everything else works i even replaced the O/D switch.
speed sensor works too.
but the transmission will still not go into overdrive, it shifts perfectly until i need that 4th gear. Im stumped, what could it be ? the solenoid pack?
please help.

It could be a bad OD solenoid within the transmission, or bad wires bad connector ect. Did you check for correct power at the plug on the transmission. Also did you reset the PCM to erase the codes? Unhook the negative battery terminal for a min or so.

How many volts should I be getting to the solenoid pack?
