I have a 1997 F-150 5.4L 4x4 off road with 99,000 miles. The first shift is hard, the second shift is not quite as hard, the third shift is almost perfect, the OD is a small jolt. Down shifting is perfect. I have had the transmission flushed with a new filter installed and the selector switch replaced. There are no indicitator dash lights on.Don't want to buy another trany----HELP
