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.

California FAQ

Common questions from customers shipping from California.

How long does shipping take from California to your Arlington TX workshop?
USPS Priority Mail from Los Angeles, CA reaches our Arlington workshop in about 2-3 business days. USPS Priority routes west through the Southwest network; usually 2-3 days given the distance. We start work the same day your module arrives and ship back next business day at the return speed you chose at checkout.

Do you accept tcm / transmission programming modules from California?
Yes — we receive modules from Los Angeles, San Francisco Bay Area, San Diego, Sacramento and the rest of California regularly. With about 31 million registered vehicles statewide, European luxury (BMW, Mercedes, Audi) are the bulk of what we see from California.
Is there a tcm / transmission programming shop in Los Angeles I should use instead?
Most Los Angeles 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 west — about 2-3 days each way.
Does California vehicle inspection or emissions testing affect this service?
California requires a biennial Smog Check emissions inspection in most counties through the BAR program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all California and federal requirements.
Does the transmission relearn happen on the bench?
No. The bench work matches and prepares the module so it communicates. The final shift-adaptation / quick-learn happens at the car, because the transmission relearns its shift behavior while driving after install. We include instructions for that drive cycle.
My TCM won't communicate after replacement — can this fix it?
Often, yes. A used or new TCM that isn't matched to your vehicle can show no-comms or limp mode. Programming or cloning it to your vehicle typically restores communication — as long as the fault is the module match, not a wiring, ground, or connector problem, which programming cannot repair.
