Hi, Whenever travelling on highways at say 90-100kmh, I go up a hill and i lose speed and the revs go down down down, and i end up around 50-60kmh at super low revs. It doesnt change down a gear to get the power. What could be the cause of this? hilux is 580,000km but serviced all fluids, replaced water pump, fuel filter, not sure what else to try.
i assume even though it doesnt change down gears it still should be able to hold 90-100 foot to the floor as they are not too steep hills. how do i get the power back on this thing?
