When the tepmtures is hot outside and we are pulling a hill when you get to the top and start to up shift it will flutter and then you down shift it will quit sometimes we have to down shift 2 or 3 gears it seems worse when engine fan is on and temp is over 200 but will run fine in cooler weather. We have had it at cat 3 or 4 times they have checked air to air and turbo the coumpter says everything is fine we have had fuel pressure check and is fine had radtioro flushed and cleaned and still this problem porsist. thank you for any help Rex

is it on the same grade when it does it? if you go to the same dealer every time, maybe they can put a data logger on it and record what the engine is doing. that will give them a better scan of what's going on. some times a dyno can not duplicate problems.

Check your fuel temp. Do you have wraped tanks?
