Long story short, I was teaching my wife to put our new Gladiator into 4 low and she just shifted all the way through from 4H to 4L without putting the main transmission into neutral. We were going the recommended 2-3 miles an hour though... Wondering how much damage, if any, that caused. No new noises and I was able to shift in and out of 4H and 4L successfully the proper way a couple of times. Just wondering what the consequences are. Any inside info as to what happens in the transmission when someone does this would be helpful for my own knowledge too.
