1. Many transmission symptoms can be caused by a low fluid level. If the fluid level is low, locate and repair any leaks and fill the transmission to the proper fluid level. Refer to STANDARD PROCEDURE for the proper repair and fluid fill procedures.
2. Testing should only be performed with the battery fully charged to avoid false diagnosis.
3. With the scan tool, read Engine (PCM) DTCs. If Engine DTCs are present, Refer to DIAGNOSTIC CODE INDEX for 3.7L/4.7L/5.7L or DIAGNOSTIC CODE INDEX for 6.7L and perform the appropriate diagnostic procedure.
4. With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information. Diagnose any Pending DTC as a matured DTC.
