Trans. Failsafe Prog.

I've just had this Trans. Failsafe Prog. popped up on the cluster a few days now on my 2001 BMW X5 4.4i and I had the same problem two year ago and it got rid off by my neighbor who reset it with his GT1 and it worked fine until a few days ago, this Trans. Failsafe Prog popped up again. Does anybody live around Long Beach, CA have GT1? I really need some help to reset this light. Please help and I really appreciate before hand.
