4. Gear ratio error codes could be a significant low fluid, but could also (and probably are, at 166 k miles) a sign of internal wear.
5. While these cars are very sensitive to low voltages, if the charging system is good, I'd doubt that you fried anything from that alone.

No I didn't have any professional mechanic look at it. Reason being is I did not want to drive to their shop not knowing what the problem is I did not want to make matters worse. This is my second X5 but it's the first time I've experienced this type of problem.
The more I think about it and the way the transmission is acting it is very likely that the fluid is low.
So here's the question if it is low what synthetic transmission fluid do I add to it?. If adding fluid will correct the problem then yes I will go ahead with the service. Especially with that many miles on it.
I do appreciate your input and I thank you very much. I will try the things you've suggested and go from there.
