Downloaded ver.4 today and finally got communication established with cars data link, but there is no .xml file that corresponds with my car. I was wondering if any users out there might have one . The car is a 1995 Lumina 3.1 vin # 2G1WL52M1S1132750. I recently replaced the transmission (4T60-E) and replaced the head gaskets and have a few problems I need to diagnose. Thanks
