Current Gear

The scan tool displays the numbers 1, 2, 3, or 4. The PCM looks at trans range position and the gear commanded by the PCM. The actual forward gear that the transaxle is in will be the lower of the two because the manual valve can override the PCM commanded gear. The scan tool displays which gear the transmission is in.
