The tranny has been serviced and fluid changed. At times it shifts normal, but ither times it is late shifting, hard shifting or feels like I am "towing" something.
what would cause erradic shifting on a 2003 Aviator? on 2003 Lincoln Aviator
My 2003 started doing this over a couple of months and suddenly at the bank drive thru, it would shift into all gears but would never engage. Repair was to the shifter cable and cost me $160.00.
sounds like you have a solonoid in the trans going bad
