hi i have a small issue with my r33 gtst. running 250bhp (186kw)
when driving along at ANY (even at 80 or 90mph) (128 or 144kph)speed and holding it at a set speed its like it drops in and out of overdrive but as soon as i come of the throtle and back on it or press the throtle it gose back to normal till it dose it again.
i have done a system check via the power button light and i got 1 long flash followed by 10 short flash so there seems no faulf on there and the atf level is ok and no burnt smell.
this is confusing me and i want to get it sorted as i have mv auto's valve body for it but dont want to put it in if the box is knackered
any help apreciated please
