Re: Better mileage with a 4 speed or C6?
OK, I admit that I haven't weighed a C6 and a T19. However, I am pretty confident that the manual trans is lighter AND stronger. I can pick up a T19 by myself no problem. When I had my E4OD (basically the same as a C6) out, it took 2 of us to pick it up, as I could not do it myself.
You have to remember to include the weight of the torque converter and the 15- odd quarts of oil in the weight of the auto tranny.
The manual transmission holds, what 3-4 quarts??
All other things being equel, a manual trans WILL get better mileage, at the expense of having to shift it yourself.
That said, I would happily swap out the 4 speed in my Dooley for an automatic. That and give up the 4.11 gears for 3.55's.
