The 2019 Lincoln Navigator is the 2nd year of the 4th-gen aluminum-body redesign. It uses the 3.5L EcoBoost V6 (the second-generation Nano version) with the 10R80 10-speed automatic. Powerful, quiet, and feature-rich. Watch for 3.5L EcoBoost timing chain stretch (the older 1st-gen had a worse reputation, 2nd-gen is improved but not perfect), 10R80 harsh shifts, and SYNC 3 quirks.
Powerful drivetrain but not bulletproof. 2nd-gen 3.5L EcoBoost timing chain is improved over the 2011-2016 generation; 10R80 10-speed has documented harsh-shift TSBs.
10R80 10-speed (jointly developed with GM) has been the subject of multiple TSBs and a class action lawsuit. Symptoms: harsh 1-2 or 2-1 shifts, shudder, occasional gear hunting.
