Why Connecticut customers mail in tcm / transmission programming

Connecticut has roughly 2.9 million registered vehicles, and European luxury (BMW, Mercedes, Audi) make up much of what Hartford-area shops and owners mail us. TCM / Transmission Programming is a bench job most Hartford shops don't keep equipment for, so owners and trade shops across Connecticut ship it to a specialist. Cross-country northeast — about 3 days each way.

Is there a tcm / transmission programming shop in Hartford I should use instead?
Most Hartford shops don't keep the bench equipment for tcm / transmission programming — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-country northeast — about 3 days each way.
Does Connecticut vehicle inspection or emissions testing affect this service?
Connecticut requires a biennial OBD-II emissions inspection for most vehicles statewide. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Connecticut and federal requirements.
Is this a mail-in service?
Yes, for supported controllers. After we verify support by VIN and module label, you ship the TCM (and donor, if cloning) to Auto Module Lab. We program or clone it on the bench, test communication, and ship it back with tracking. If your controller isn't bench-readable, we'll tell you before you ship.
Can you clone my original TCM onto a replacement?
Yes, on supported standalone / external TCMs. We copy your original TCM's data onto the donor unit so the calibration and stored adaptation carry over where readable, then test communication on the bench. Support depends on the controller, which we verify by VIN and module label before accepting the order.
