For 1990-2009 cars

The Transmission Scan Tool Data List contains all Transmission related parameters that are available on the scan tool. The list is arranged in alphabetical order.

Use the Transmission Scan Tool Data List only after performing the following inspections:

• | Powertrain On-Board Diagnostic System Check is completed.

• | No Diagnostic Trouble Codes (DTCs) are present.

• | On-board diagnostics are functioning properly.

Scan tool values from a properly running Transmission may be used for comparison with the Transmission you are diagnosing. The Transmission Scan Tool Data List represents values that would be seen on a normal running engine.

Important: Do not use a scan tool that displays faulty data. Report the scan tool problem to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
