My computer crashed, lol, else that wouldda been one of the shortest AJ posts ever!
Because the column shifter is like a big rubber band. If you don't push hard enough nothing happens, but if you push just a tad too much it might jump a gear or worse hit neutral. Downshifting is even worse,cuz if you go from third to first, your rear wheels will will skid and you have a good chance of losing steering control. You will be spending so much time concentrating on not fubarring the shift, you will become a hazzard to all the other drivers on the road. Where is the control in that?
On the street, do yourself a favor and get a semi-auto kit and a floorshift with a stout shift cable. Just as much up-shift fun, auto backshift, or not,variable throttle pressure,and put in D so your girlfriend will ride with you.
