I have only had my X for a few months (used) and in the beginning I didn't notice any transmission issues. Now in the morning and when I get ready to leave work the transmission is not 100% working. If I step on the gas the car does not respond normally. It takes about 15 - 25 seconds before it accelarates normally. The fluid was okay when I first got it, maybe it has lowered since? In about 2 weeks it is going in for the 30000 mile inspection. I hope the dealer can fix the problem. I'll tell you what I learn.
