Hi, I have a ltx diesel auto and have been reading about others poor fuel consumption like myself. One thing with the auto doing 30 on the flat it holds on to the revs and keeps its self in third gear, when the engine would be still quite happy in fifth and return a little more economy. Is it possible to remap a gearbox settings. Now if that is not possible I could over come it by putting it into manual, the only thing is and I do not know if my car is at fault but I can manually change down and rev the b------s off it, but try to change up and it does not like it, say again if I was doing 30 if I manually changed up I would be lucky for it to change up to fourth even then I would have to speed up a bit first and I certainly would not get fifth also if the speed dropped a little I would be back down to third again. How is that manual changing when the auto side of things takes over although I can make it rev on the changing down side of things, any thoughts thanks.
