Why California customers mail in tcm / transmission programming
California has roughly 31 million registered vehicles, and European luxury (BMW, Mercedes, Audi) make up much of what Los Angeles-area shops and owners mail us. TCM / Transmission Programming is a bench job most Los Angeles shops don't keep equipment for, so owners and trade shops across California ship it to a specialist. Cross-country west — about 2-3 days each way.
