Got a GPX FTO with the 4spd triptronic auto. When I bought it (cheaply off a mate who was moving and needed to sell quickly) it was slipping when changing gears. Basically revs up in the gear change. Doesn't slip at all once the gear is selected.
Anyways, I suspect a faulty box and get a replacement from the wreckers. Install the box, put the proper Mitsubishi oil in.... the the bastard does the exact same thing



Am I just extemely unlucky, or could there be something else causing this particular problem???
Any help/suggestions would be much appreciated!
Cheers, Ant
