I am having some fuel economy problems. 10mpg on a 350. I would like to put a 4 speed auto in my truck that currently has the turbo 350 in it and 3.08 gears. I cruise at 2300rpm. I know that it is possible to do this but I need some help.
1)I've read that there is transmission mounting problems and I would have to move the brace, is this true?
2)Something about the torque converter
3)drive shafts lengths, how long and could I steal on off a different truck.
4)How would I deal with the extra gear on the shift column.
5)Is it actually worth my time or should I just accept the fact that these trucks suck the gas down.
