Hi guys this is my first time post here.
I got my altezza auto (since manual is expensive and rare) for last year and modified some of it include locked 4.556 final drive (rip 1 gear)
While i accelerate hard to test 0-100, the first gear automatically shift into 3 or 4 gear. I don't know what happen even tho i tried many time but still can't shift in following order.
In slow acceleration the gear a in order shift.
Other is i can't put my car into M(manual mode) but instead overdrive mode. I try many time (including press button, pwr and etc) but still no number is show.
Is there a problem in gear box or ecu?
