I bought a 2002 530i a year and 1/2 ago a few moth ago I started to have the following problem: when I am driving and I go in a curvy road or up a hill or down my trans with go on safe mode immediately and shift down to 4 gear, if I stop and shut the car off and remove the key it will go back to normal 'till the next hill or curve, unless i get to it very slow. I am thinking of some kind of sensor or something loosed some where that's telling the computer that it need fluid or something like that, I checked the fluid and seem to be full and as a matter of fact I changed the fluid but still the same problem, some times I feel it sort of bucking some what as well....but not sleeping at all.
Please fellows throw me a bone on this one.
Millage is 142k and the car is immaculate inside and out.
