My Dodge 2500, Diesel, Automatic. w 250,000 miles. 1994.
The cruse and overdrive will drop out if the road rough enough to bounce the brake peddle. I added a spring and replaced the switch. The same problem.
Install a wire to the OD solenoid and at about 65 the OD will lockup and the convertor will lockup. Without power you don't have the OD and Lock up convertor.
Questions;
Is there a switch in the throttle linkage?
Where and what do I look for?
