Top speed is 45 mph

I've had to replace the input/output sensors on my 96 two times. the last time the connectors were also replaced since they are located under the battery and there was evidence of battery leakage in the connections. Also if the isolator between the drivetrain and the lower radiator support is bad, engine torque puts a strain on the harness at that location, which may or may not contibute to the problem.

This particular year and model has problems with the transmission module. before you go on a whim... make sure your van is shifting gears. when the module goes out it will stay in second gear and not shift to other gears. watch your rpm's to see if it shifts with your speed. if the rpm's dont drop and just continue to advance your transmission is not shifting. the best option if you are not a home mechanic is to take it and have a diagnostic done. there is also the possibility that your input or output sensors are also bad. which also controls when your vehicle shifts and the speed. another thing to look for is if any of the plugs have bare wires and are grounding out. i hope this gives you a place to start..........
