I own and 1996 328i auto that recently had some minor flood damage and now it does not want to shift into fourth. It shifts fine from first to third but no fourth. I had it looked at a bmw dealer and they said the tranny looked fine and the fluid was good and said it is possibly to do with the electronic control. I did not have them look into it any further as i wasted to see what i could find out in other places. could this be an electronic control problem and if so what could i do to check and fix the problem? Thank you for any info on this.
