my tranny since I bought it felt like it wanted to "work", for example, when Im pressing on the pedal it kicked down to a lower gear, I felt it was normal?

Sometimes, it feels its in a guessing game, like from 3 to 2 to 1 and then up.. I honestly felt it was ok?

I have experienced a bad transmission on another car, for example it slips on rpms, is it not the same symptoms for a BMW X5?
