Right, i know its not scientific aba testing, the traffic in the uk precludues that most of the time, but a several hundred mile drive reveals a new mpg - 14.75uk mpg which is about 12.2 usmpg from a uk 11.5, so an immediate 28% improvement from the last run.

Anyone know about allison at545 gearboxes, im sure mine isnt right, as i can do 50 to 65mph in fourth, at 2200rpm without the engine changing revs at all. Sure, theres going to be a bit of slip, but that much? 50 mph up hill, 65 on the flat, more than that downhill.

Edited to correct way round conversion, after 5 hours drive im tired.
