My 2006 325 Cic has an automatic transmission and about 72,000 miles. I noticed an approximately 8 inch round area of what appears to be transmission fluid. It seems to be leaking slowly. The transmission seems to be shifting OK, I think but not sure. I have contacted several repair shops, including BMW dealers and am getting many different responses. I understand the my car's transmission is supposedly "sealed" and a lifetime transmission. Not sure what to do and looking for guidance including a recommended repair shop. I live in the Fairfax/West Springfield area. Thanks
