when was the last time the transfer case, front and rear differential oils were changed?
also, if driven normally the transmission rarely uses first gear. Normal start stop driving will use 2nd to move off,(saves fuel) Only in manual mode or in low range will it use 1st to get the most benefit of the torque converter lock-in up nice and early.
