96 Grand Caravan going into Limp Mode after highway driving
The past two days, after travelling about 30 miles at highway speeds, the van will make a noticeable clunk/shudder at a stop light and go into Limp Mode. The van was shifting and driving fine the entire day before the highway travel and worked again after resting overnight. My transmission was rebuilt about 30k miles ago after going into limp mode on a long trip (requiring an extra long trip home)! Any suggestions before I send it to the shop?
