Guys please help as I'm stumped. I have a BF Mk2 with 6spd auto. Recently my car will not change up to 5th or 6th gear while driving normally. It will just hold in 4th gear and won't change up unless you put it in sport mode and manually shift it up. But when you put cruise control on, it shifts through all gears normally and has no issues. Anyone had a similar problem?
