Hey, ya'll.
2017 Challenger 38" (automatic transmission) owner here. My husband and I have looked in our Ford owners manual and the overall manual that came with our Challenger and have also tried to look online and cannot seem to find an answer to these questions:
What is the proper way to drive through mountains with regard to taking the best care of your brakes/engine as possible? Based on my research, I have concluded that I should approach a downhill grade going fairly slow (40ish) and if I need to hit the brake, hit it hard to reduce speed 5 mph or so (at this point the RPMs increase to help the engine slow down so I don't have to keep hitting the brake so much) and try not to brake more than once a minute. There is no redline on the RPMs dial, but we never push that above around 4000. We want to do what is best for the engine and for the brakes, but we can't seem to find any further info on this.
Also, what are the 1st, 2nd and 4th gears for? Can these be shifted to on the fly? Or must one stop the rig to put it into one of these lower gears during climbing or descending mountain hills? Thank you for your advice!! Sorry if these questions are stupid. But I really have tried to research and am not coming up with much beyond what I've stated above. The runaway truck signs scare the heck out of me and we don't want to be one of those guys!
