check and adjust the fluid level in accordance with the Service
Information.
Note: Always perform diagnostics with a fully charged battery to
avoid false symptoms.
With the DRB III , read Engine DTCs. Check and repair all engine
DTCs prior to performing transmission symptom diagnostics.

Most DTCs set on start up but some must be set by driving the vehicle such that all diagnostic monitors have run.
