Confused Lincoln Trans
Some 2012-2013 Lincoln Navigators quipped with the 6R80 transmission, and built on or before 4/8/2013 may exhibit a transmission engagement in 5th gear when starting. The “wrench” indicator and/or seat belt minder may be illuminated, the speedometer may read zero and the odometer may display dashes while driving.
Symptoms may clear after an ignition cycle. DTCs P0720 and P0722 may or may not be stored in the powertrain control module.
Replace the molded leadframe on the main control assembly. Refer to workshop manual section 307-01 (shift solenoids). Note that replacement of the shift solenoids is not required for this procedure. The molded leadframe is available as P/N AL3Z-7G276-A.
