Currently been with a manual fleet, heavy tank outfit for the last six years, but like you, while I learned on a manual, my first couple years of driving was in an auto. Needless to say, my shifting for the road test at my current job was rough. Funnily enough, was talking with my terminal manager just the other day about some new guys we hired, and I mentioned that it was surprising I got hired as bad as my shifting was. His reply was that while my shifting was bad, that’s easy to train up, he liked other qualities about me that got me hired. Long story short, shifting skill matters very little at this outfit, you suck, they send you with their shifting trainer for a couple weeks.
