For Houma Drivers
Why Houma Drivers Choose Elite for Engine Rebuilds & Transmission Service
Houma's oilfield economy keeps trucks working hard — and eventually, even the best work truck needs a full engine rebuild or a transmission swap. Elite Custom Automotive's shop in Lockport is 19 miles, 23 minutes up LA-24 and LA-1 — faster than waiting weeks at a Houma dealership for an engine teardown estimate, and roughly half the price of dealership labor. We see customers from Bayou Cane, Schriever, Gray, and Houma East regularly: fleet trucks needing 6.6 Duramax rebuilds, personal trucks with blown Cummins 5.9s, and family vehicles needing a transmission swap. We do full engine rebuilds the right way — proper machine work on the heads and block, factory-spec internal tolerances, no reused gaskets, no shortcut cleanup. For transmissions, we don't do internal rebuilds; instead we install full reman or new transmission units. That's a more honest answer for Houma customers — internal rebuilds in our climate often need a second repair within 2–3 years, while a full unit swap is straighter pricing and lasts longer. Call us at (985) 258-1414 for current warranty terms on the unit and the install — terms vary by the reman supplier. We also handle the day-to-day Houma calls: head gaskets on the 5.3 LS, timing chain replacement on the 6.4 Power Stroke (a common Houma problem on older Super Duty work trucks), full fluid service on the Allison 1000 and 2500. Free diagnostic before any rebuild quote. (985) 258-1414.

Common Questions
Houma FAQs
I drive a 6.6 Duramax fleet truck. Can you handle a full rebuild without sending it to the dealer?
Yes. We've done multiple 6.6 Duramax rebuilds — bottom-end, head work, injector replacement, the whole thing. You'll pay roughly 40–50% less than dealer labor and get a real answer on what's actually broken vs. what they'd "recommend replacing while we're in there."
Why don't you do internal transmission rebuilds? The Houma shops do.
Internal trans rebuilds in South Louisiana climate hold long-term about 50% of the time. We've watched too many customers pay $3,500 for a rebuild that fails within two years. A full unit swap is straighter pricing and more reliable long-term. Call us for current warranty terms.
How long does an engine rebuild keep my truck out of work?
V8 gas rebuild: 2–3 weeks. Diesel rebuild (6.7 Power Stroke, 6.6 Duramax, Cummins): 3–5 weeks. We give you a real timeline upfront, including any waiting on parts or machine work.
Do you handle fleet billing for oilfield service companies?
Call us at (985) 258-1414 to set up fleet billing for your company — we'll walk through the paperwork and account setup with your office.
My Cummins has the death wobble. Is that a rebuild or a steering issue?
Death wobble is almost always a steering/suspension issue (track bar, ball joints, or worn front-end components), not an engine issue. We'll diagnose and quote the steering work — it's typically a fraction of a rebuild cost.
