Some vehicles may exhibit one or more of the following symptoms: transmission default to second gear, erratic shifting, failure of the speedometer and diagnostic trouble code (DTC) P1871 that cannot be diagnosed using the standard procedures in the service manual. These symptoms could be caused by the Vehicle Speed Sensor (VSS) contacting the transfer case rear output shaft tone wheel. Owners should replace the speed sensor and install the shim PN# 5745239 to resolve this issue.
