hey all, my brother just picked up a 2000 5 speed wrangler. I taught him how to drive it a few days ago and he got it in his head from the internet that its normal to always be at 3-3.5k rpms. because of this, he is doing things like intentionally driving around the town going 15-20+ mph in first gear with the engine screaming. He seems to think there is some magic number to when to shift and doesnt feel any issue when hes at 4k rpms pulling out of a stop sign in first gear and stays in first until he should be in third, engine SCREAMING. i want him to understand that he needs to just do what the car wants to do and shift when it wants to shift, go by the feel.. not just do what someone in a forum or reddit said they do. does anyone have any advice on how to go about this? im worried about the damage he may be causing by exclusively being 1 gear under where he should be, and running it so heavy 24/7. thanks.
