: Yes, I believe that's how we do it.

: BUT, I do not know the code. Our software guys don't let me near the keyboard.

: We've refined it down to the point where it takes under two seconds.

I don't quite understand the partial foreward, partial backwards and all that stuff. We have a simple gear shifting system that works everytime, takes about half a second to shift, and works with the press of a button. I wont go into much detail, but the code is only about 10 lines long and easy to read. It is really helpful because we can use high gear for speed, but when going up the ramp we lose traction so we go into low gear and keep going.
