I hope someone can shed some light on my problem. I started having problems with 2 to 3 up shift. It will slam into 3rd gear instead of the smooth shift that normally takes place. This problem will occur hot or cold and will shift fine and then 2 or 3 shifts will slam into gear. All other upshifts or down shifts are fine. Since the car was new there was a small leak between engine and trans but not enough to be concerned about but when this shift problem started about 18 months ago I finally decided to take it in. The dealer took the trans out and changed seals, etc. At that time I mentioned about the intermittent rotten upshift problem. Well when I got the car back all seemed ok for about 2 weeks and slowly the upshift problem started again and is to the point about 10 months later is just as bad as before. Should I be demanding a new trans or possible trans computer from the dealer. They will say no to the new trans - will need to fix it!! Well warranty is up at the end of the year and I don't have time to CHECK if it's fixed. The problem started at 14,000 Km and only has 28,000 on it now. Anyone has any ideas, though about disconnecting the battery to reset the computers.
