1991 Dodge Ram Wagon B350 Question: transmission does not shift into overdrive



, 5.9L V8, Ridgely, TN, February 27, 2010, 18:38

transmission does not shift into overdrive. the light in the switch is off, pushing the switch in does not change anything, is there a overdrive switch relay that could possibly be bad. If so where is it located?

    I have the same. Overdrive trouble could be solenoid left side trans above park/neutral swicth, Trany temp switch I have not located, coolant temp I have not checked and speed sensor that I changed. CC don't work
