The Cruise Control and Speedometer May Fail Due to Speed Sensor Issues on Dodge Grand Caravan

Problem Description and Possible Solution

Defective speed sensors on the transmission can cause problems with the cruise control and speedometer operation, as well as erratic shifting. The connectors on the sensors can corrode and/or the connector terminals can spread (poor connection), which will create similar symptoms. Any of these problems can cause Check Engine Light illumination.

Cruise control totally stopped working. Two weeks ago all my controls (heat, ac and such) stopped working. But didn't affect my radio. My controls started working after a day, but now the cruise control stopped working.
on vacation and one of the transmission sensors failed and van would not shift out of gear ( or over 30 mph) replaced sensor and it was good
