The really weird thing that I dont have a clue about and had me super pissed off was I missed 4th gear twice, its like the car would not go into 4th.
I have never had my car to the track, but I have had the same problem - usually getting on the highway.
It is not necessarily under WOT either. It can simply be trying to pick up speed to merge in, and it does not want to go into 4th. It is a bit disconcerting when you merge in front of someone - but can't accelerate after that.
It is not a consistent problem - just something that occurs from time to time.
