Hi guys,

Im posting this on behalf of my father so i will try to give you as much detail as possible.
He has a 98 Fairlane concorde (6cyl) model, it has approx. 225000kms on the dial. Problem is as the car heats up the gearbox slips (kicks hard), generally between 1-2 2-3 gears. It does not do it while the car is cold. It has been in for an oil/ filter replacement but this has not solved the issue. I myself have driven this car and it gets really bad, any ideas?
