Hi all, Have looked right through the forum and have found some similar topics, but none with the exact same problem as mine. If I'm driving along the freeway at, say, 80kmh and accelerate to pass someone the box will drop from 6th to 4th which is great, but when I back off again after passing them it won't upshift to 5th or 6th. It just holds 4th forever and cruises along in 4th at 120kmh until I shift switch across and manually upshift. Now, I've been looking on here for a while and have tried all of the remedies I've found: - had the gearbox serviced (which it was probably due for anyway - 85000km) - no change - new tyres as the rears were worn - no change - tried backing off gently so the box doesn't think I'm about to go into a corner and hold the gear - no change - tried disconnecting battery overnight to reset mapping - no change - tried turning off stability control - no change The other thing I've noticed is that if I activate the cruise control the box will shift to 5th then 6th PERFECTLY! I'm guessing/hoping it's something in the mapping that I can reset or change but apart from that I'm rapidly running out of ideas, so any thoughts you have would be a big help! Cheers Kyle PS: car is 100% stock, 90000km, bf mk2 07 upgrade.
