For Lockport Drivers
Why Lockport Drivers Choose Elite for Engine Rebuilds & Transmission Service
When a Lockport driver's engine is on its way out — or a transmission is slipping on the LA-1 bridge climb — Elite Custom Automotive at 5609 LA-1 is the same-town option. Local sugar cane farmers, oilfield commuters, and bayou-side daily drivers bring us everything from blown 6.0 Power Strokes to LS swaps to high-mileage Allison work trucks. We do full engine rebuilds (bottom-end, gasket, internal — proper machine work, proper torque specs) and engine swaps (LS, Coyote, Cummins). For transmissions, we don't do internal rebuilds. Instead, we do full transmission swaps — replacing the entire unit cleanly. That's an honest choice: internal trans rebuilds in South Louisiana humidity rarely hold long-term, and customers end up paying twice. A full swap is straighter pricing and lasts longer. We also handle the everyday work: timing chain replacements on Ford 6.4 Power Strokes (a common Lockport problem on older Super Duty work trucks), head gaskets on the GM 5.3 LS, full fluid services on 6L80 and 10R80 transmissions. Honest diagnostics first — we won't recommend a $4,000 rebuild when a $200 fix solves it, and we won't recommend a $200 fix when you actually need a rebuild. Drop your truck off, call (985) 258-1414, or stop in. Lockport locals usually get a same-day diagnostic appointment.

Common Questions
Lockport FAQs
My 7.3 Power Stroke is making weird noises. Can you diagnose before quoting a rebuild?
Always. We do a full diagnostic including compression test, oil pressure check, and visual inspection before any rebuild quote. Sometimes it's an injector or oil cooler — sometimes it's bottom-end failure. You'll get a real answer, not a fear-priced quote.
Why don't you do internal transmission rebuilds?
Internal trans rebuilds in South Louisiana climate tend to have about a 50/50 hold rate over 2–3 years. Full unit swaps are more reliable, straighter pricing, and usually within 20–30% of rebuild pricing. It's a more honest answer for the customer's wallet long-term.
How long does a full engine rebuild take?
For a daily-driver V8 (5.3, 5.7, 6.0): 2–3 weeks once the machine work is back. Diesel rebuilds (6.7 Power Stroke, 6.6 Duramax, 6.7 Cummins): 3–5 weeks. Project trucks with custom work can run longer.
Do you do LS swaps?
Yes — LS swaps are one of our specialties. We've done LS swaps into older Chevy and GMC trucks, Jeeps, and a couple of full project builds. Talk to Colin about your specific project.
What does a transmission swap actually include?
New transmission unit (rebuilt or reman, depending on availability and budget), new fluid, new filter, new torque converter, and a road test before delivery. Call us at (985) 258-1414 for current warranty terms on the unit and the install.
