I've driven stick shift vehicles for the past 15 years, and I've made it a matter of personal habit to routinely downshift as a way to save my brakes - especially on long downhill stretches. Being my Land Cruiser has an auto tranny, I find myself shifting from D to 2 to slow the vehicle down quite often. Is this bad for an automatic transmission? Are there some negative long term effects I should be aware of? Like I said I am rather new to automatic transmissions and would hate to screw it up. Does anyone else do this or has feedback on downshifting with an auto tranny?
