Why Michigan customers mail in duramax lb7 / lly ficm repair

Michigan has roughly 8.1 million registered vehicles, and domestic trucks & SUVs make up much of what Detroit-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Michigan — we see a steady stream out of Detroit, Grand Rapids, Warren. Cross-region north — about 2-3 days each way.

What we see from the Midwest

Salted winters plus long agricultural and towing duty cycles are the pattern we see from the Midwest. Modules on these trucks accumulate an unusual number of thermal cycles — cold soak overnight, hot underhood by mid-morning — and that is the loading that eventually opens a marginal solder joint. It is also why an intermittent fault that follows temperature is worth mentioning on your job note.

Michigan FAQ

Common questions from customers shipping from Michigan.

How long does shipping take from Michigan to your Arlington TX workshop?
USPS Priority Mail from Detroit, MI reaches our Arlington workshop in about 2-3 business days. USPS Priority routes north through the Central network; usually 2-3 days. We start work the same day your module arrives and typically ship back next business day at the return speed you chose at checkout.

Do you accept duramax lb7 / lly ficm repair modules from Michigan?
Yes — we receive modules from Detroit, Grand Rapids, Warren, Ann Arbor and the rest of Michigan regularly. With about 8.1 million registered vehicles statewide, domestic trucks & SUVs are the bulk of what we see from Michigan.
Is there a duramax lb7 / lly ficm repair shop in Detroit I should use instead?
Most Detroit shops don't keep the bench equipment for duramax lb7 / lly ficm repair — 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-region north — about 2-3 days each way.
Does Michigan vehicle inspection or emissions testing affect this service?
Michigan has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Michigan and federal requirements.
Does a repaired module need programming afterwards?
In most cases no. It is still your module with your VIN and calibration, so the truck recognises it exactly as before. If a specific repair requires a programming step, we read your existing data first and restore it, so the module goes back configured to your truck rather than blank.
Is there a warranty on the repair?
Yes — the same 6-month programming and workmanship warranty that covers our other bench services, and it covers the repair we performed. It does not extend to a different section of the board failing later, or to faults elsewhere on the truck that were never part of the repair. We will always tell you which of those we think you are looking at.
