Hi guys.
I've got a problem.
Car is Seat Exeo 1.8t CFMA.
Stock gearbox with 6 gear, swapped to diesel one with 6g.
The problem is that, when u shift up to the 6th gear, the car doesn't recognize it,
and have some bad behaviour of throttle body. When u press pedal, or lift it, there is hard knock, something like broken engine mount, only on this 6th gear.
So i fixed, and set properly a nvquot, and thought it will be ok...
Car has economizer ( which is showing on cluster when to shift up/down and showing current gear ), now the car recognize 6th after shift, but only for 1-3s, and after that time, doesn't display any gear, with the same problems as above. For this few seconds everything seems running good.

I don't even have idea where to search, which module can cause this kind of problem, maybe armd...
It looks like some kind of global speed/gear ratio limiter or something else.
I am sure that i set properly nvquot, with many of attempts, even when i set nvquot as final drive is recognized as a 5th gear, same problems.
