[V8] gearbox swap questions

[Scott DeWitt]

In the C5 a 6 speed conversion will yield approx 20-25hp additional on the
dyno and 2-3 mpg on gas 6 speed ratios and 5-8mpg using diesel trans
ratios.

Automatic are becoming commonplace in most new cars not because they are
more efficient than a manual but rather people are lazy and manufacturers
have much more control over engine operation, emissions, and warranty
issues if a computer is shifting gears versus the driver.

There is a stand alone controller for ZF boxes but to be honest if the OP
runs the numbers he will never recoup the money spent with fuel savings.
The 3.6 V8 in a 4000+ pound car is not intended and never was to be king
in fuel efficiency.
