I have for a long time wanted to change my 65 box to something else, something that doesnt say "the car is moving lets go straight to 3rd gear" but what choices are out there?
A few years ago I considered the ZF 6 speed box as is fitted to the BMW735i cars, worked out the ratios and rpm values as compared to the HP and weight when compared to the 735i and that looked like a real winner with side advantages of a lot less box weight and improved box efficiency(better fuel economy).
The big problem would be marrying the box to the engine and then setting up the electronic control :? it all stsrted to seem a little to hard.
What other boxes have people used and what are their relative advantages? really doesnt seem to be any point in getting under 5 speed and an overdrive gear would be a must have as the P6B's rev far to high at any thing above city driving speeds.
