Looking at a 2000 sport 4.0 with the 3 speed auto. When you start out driving it, it has a whine in first that continues until it shifts into second. Sounds like the whine of a gearbox in super low gear. Shifts fine and no other noise in second or third. Seller said this is normal and common??? Going to drive another one probably this weekend to compare. This was the first one I have ever driven, except for a CJ years ago.
