Hi guys/gals. I recently purchased my f150, its got a manual trans (I had never driven a manual). I've driven it for a few months and still have trouble finding the sweet spot and many times there is some jerking when going into first and from 1st to second. Is this putting excessive wear on my trans? (clutch)? The truck is fine my b in law and neighbor have used it and they say the truck runs smooooth... Any tips????
