I wonder if anyone has had similar problems with an automatic gearbox, after a few days of rain we had some deep puddles in the lanes, nothing that would cause a bow wave or anything,but after driving through these puddles my gearbox started to upshot really quickly at first I thought it was slipping.however it seemed to reach three thousand revs and change up. Has anyone had similar,should I be worried as iv only had the car a year on a 2008 plate.

Gearbox was in Drive or Sport, by any chance/mistake?
Terrain response was on General Programs or any other program?
