i have a 4×4 automatic transmission SUV.
few days from now, i will be travelling out-of-town. and there’s a lot of ascending and descending roads and it’s all concrete
should i use the 4H or 4L? what about my transmission, should i shift to lower gear?
but the manual said i should NOT use 4×4 in dry roads…what should i do if the road is dry and concrete but has inclined /declined surface?
can it possibly damage my transmission?
pls advice. thanks
