CHECK IF DTC IS CURRENT
NOTE:
The Transmission Control Module stores under Environmental Data the transmission operating conditions when the DTC was set. Before erasure of any DTC, record all information pertaining to the DTC, even if there is more than one DTC stored.
1. With the scan tool, erase transmission DTCs.
2. Using the Environmental Data previously recorded, drive the vehicle and try to duplicate the conditions in which the DTC originally set.
  Did the DTC P2767 reset?
  
  Yes
  - Go to 2.
  No
  - Go to 10.
