I suspect that a non-locking torque > converter is the culprit. Can anyone confirm this? My understanding is that this would be normal - the torque convertor locks whilst cruising on the level, but unlocks when demand is placed on the gearbox, in this case, when progressing up an incline. Once it has unlocked, your revs increase accordingly whilst you go up the hill, and once you reach straight and level conditions, you'd expect the torque convertor to relock. At least, that's my understanding of it. Simon
