Check your VSS gear for wear. You didn't specify what engine/transmission combo you have, so here's a chart that might help:

2.73 P205/65TR15 Auto 8 18 C7SP-17271-B Gray

This problem is usually caused by the vss. ( vehicle speed sensor) It is an electrical signal generator that plugs into the rear extension housing of the trasmission. All you have to do is undo 1 bolt and 1 connector to change it. It is located on the driver's side of the trans, about six inches forward from the driveshaft.
