question, i leave work after 12 hours and drive 3/4 miles until i hit an on ramp. the question is it is a fair level of ascend. with a corner in the middle. easy in fourth gear up to 50 mph about 3500 rpm do i shift to 5 th, or do i wind out 4 th another 1/4 mile until it's flat. when i shift into fifth. it seems to bog the engine a bit. better to wind the engine out or shift too soon. excuse my ignorance in this dept.
