This entire story illustrates yet again the beauty of the manual transmission. Depress clutch (or not), take it out of gear, end of problem.

And if (seldom) you have to repair it, you can do it in the back of a small shop in Avezzano with ordinary hand tools for the most part. Im glad you brought this up. I am not really a fan of automatic slushboxes.

I don't want to be shifting if I've driving a bunch of kids or adults around. I wouldn't want a manual in a large family car any more than I'd want an automatic in a small VW or Fiat. The manual will die out along with the piston engine. The cars of the future will be probably be powered with electric motors. My guess is that electric motor controllers could be programed to simulate the torque and shift take-up of piston engines. Sadly, that'll probably be the only legacy of the age of the piston engine and manual gearboxes that will survive.

I doubt there's much validity that vacuum assisted brakes were required because of the advent of disk brakes. My first car, a 67 Barracuda had drums and vac boost, as did most cars of the time. That one had a tiny V8 - a 273! Of course, today that would be a large engine - 4.5L. :-) |
