Over the past week, the tranny light has come on during cold starts in the morning (-5 degrees Celcius) in my 1992 e36 325i 4DR. The tranny would skip 1-2-3 and go right into 4th? After driving like this to my coffee stop, I would come out the tranny light would be off and the tranny would catch all gears properly. This went on for 5 days until one morning (this tuesday = really cold), the tranny light was on all day long and no 1,2, or 3?

Immeadiately I took it to my old Scot Bimmer specialists (old dealer guys) and they said probably low fliud. Left the car over night they scanned the error code, checked the fliud and it was two "cups" low = not the problem. The error code came up as "transmission pressure" but what does that mean? Even they didn't know!

The car was kept indoors that night and when he test drove it in the morning, it ran fine? But after being left outside all day the problem came back, no 1, 2 or 3?

There are no leaks and fluid is proper and they don't know what to do? Anybody out there have any ideas? Please advise ... I miss my car! Thanks!!!
