🔥 263K MILES & ONLY 2 GEARS LEFT — BUT IT MADE IT HOME!

This 2006 Chevy Silverado 1500 made the long journey back to Florida with only 1st and 2nd gear hanging on. Once it got to us, we got straight to work and turned it around quickly with a few upgrades and some much-needed maintenance.

• Removed the failed 4L60E
• Swapped in a nice low-mileage GTO 4L65E
• Added a Corvette servo for firmer, more positive shifts
• Replaced the original engine and transmission mounts — 263K miles on the factory mounts isn’t bad!
• Tracked down and repaired a small coolant leak
• Finished it off with a few recalibrations using HP Tuners

Now it’s shifting right, running strong, and back to work where it belongs. 💪

High mileage doesn’t mean it’s done — sometimes it just needs the right repairs to keep earning its keep.

🔧 2013 GMC Sierra 1500 — SAFE, SOLID & BACK ON THE ROAD! 🔧

This GMC came in needing some much-needed attention, and once we got into it, we found a few issues that definitely couldn’t be ignored.

The driver-side front wheel bearing had started separating, causing uneven brake wear and damage to the rotor. From there, we went through the braking system and got everything handled properly:

🔹 Full front & rear brake service
🔹 Both front wheel bearings replaced
🔹 Leaking rear wheel cylinders replaced
🔹 Rear drum brakes rebuilt
🔹 Wheel adapters removed
🔹 New rear axle lug studs installed
🔹 Leaking valve cover gaskets replaced

No shortcuts — just fixing what needs to be fixed and making sure it leaves better than it came in.

✅ Safe. Solid. Leak-free. Back on the road. 💪🔧

🔧 23 YEARS OLD. 174K MILES. STILL PUTTING IN WORK. 💪

This 2003 Chevy 2500HD came in for a full work-up, and considering it made it 23 years and 174,000 miles on most of its original parts, we’d say it held up pretty damn well.

First up – oil leaks:
• Rear main seal
• Oil pan gasket
• Valley cover gasket & knock sensor grommets
• Cam sensor O-ring

Next — drivetrain mounts:
Both engine mounts and the transmission mount had seen better days, so those were replaced.

Then we tracked down a random misfire. During inspection, we could actually hear the spark plug wires arcing against the exhaust manifolds. A fresh set of ACCEL ceramic plug wires took care of that problem.

Rear passenger door ajar warning:
The customer had already replaced the door latch/actuator, but the warning was still there. After checking the wiring and ruling out any breaks or connection issues, we traced the problem back to a failed BCM.

❄️ Last up — overheating at idle & weak A/C performance.
The original 23-year-old clutch fan had finally given up. Instead of replacing it with another mechanical fan, we upgraded the truck with a BP Automotive electric fan conversion harness.

A clean install and proper tuning later, the truck is holding temperature exactly where it should — and the A/C is blowing a crisp 38°F at idle. 🥶

One truck. Multiple problems. Diagnosed, repaired, upgraded, and ready to get back to work. 💪🔧

Don't wait until your A/C quits in the middle of a Florida summer. 🥵❄️

This 2015 Ford Focus 2.0L came in with a valve cover leaking oil and an A/C compressor that had completely locked up.

✅ Engine cleaned and degreased
✅ Oil cleaned from the spark plug holes
✅ New compressor, condenser & expansion block
✅ Lines and evaporator core flushed
✅ New seals installed
✅ Vacuumed and recharged to spec

The payoff? Ice-cold 36–38°F vent temps and another vehicle back on the road with repairs done right—not patched together.

If your A/C isn't keeping up with the Florida heat, don't wait until it leaves you stranded. Get it fixed before it gets worse. 💪

🔥 Florida heat doesn't care what you drive... neither do we. 🔥

If your A/C isn't keeping up, now is the time to fix it. Whether it's a 1989 or a 2026, we'll get you back to driving in comfort.

This 2009 Pontiac G8 GT came to us after we diagnosed a failed A/C compressor back in November. The owner finally decided they'd had enough of the Florida heat—and we don't blame them.

Instead of taking shortcuts, we repaired it the right way:
✅ New A/C compressor
✅ New condenser/drier
✅ New expansion valve
✅ Flushed the refrigerant lines and evaporator core to remove debris from the failed compressor
✅ Vacuum tested and recharged to factory specifications

The result? A crisp 40° vent temperature and an ice-cold A/C system ready for the hottest Florida days. ❄️

Don't wait until you're sweating through your commute. If your A/C isn't blowing cold, let us diagnose it and fix it right the first time.

💰 A $2,800 Repair... That Never Needed to Be Done.

This 2011 Nissan Altima came to us after another local shop quoted the owner—a single mother—nearly $2,800 for what they called a timing belt replacement.

The problem?

This engine doesn't even have a timing belt, it utilizes a timing chain setup.

After a thorough inspection, we found the real issue. During a previous repair, the belt tensioner bolts had not been properly torqued. Over time they backed out, snapped off flush in the engine block, and leaving the main belt drive system the issue.

Instead of replacing parts that weren't needed, we:

✅ Removed the broken bolts from the engine block.
✅ Reinstalled the belt tensioner correctly.
✅ Installed a new serpentine belt.
✅ Repaired a broken alternator connector we found during the repair.
✅ Cleaned and degreased the entire engine bay.

The result? A safe, reliable repair that saved this customer thousands of dollars.

We don't believe in selling repairs you don't need.We believe in accurate diagnostics, honest recommendations, and fixing it right the first time.

At Besnier Performance & Fab, your trust is worth more than any invoice. 💪

Not every repair happens on a clean shop floor.

Sometimes the job has to be done in the dirt, in the driveway, or wherever the vehicle sits. The location doesn't change the quality of the repair. We do it right no matter where it takes place.

This 2005 Hummer H2 6.0L came to us with a major oil leak and dangerously low oil pressure. The owner had already been told by another shop that the oil pan gasket was the cause of both issues. After hearing that diagnosis, we knew there was a good chance we were going to find more problems.

Once inspected, we found several critical mistakes:
❌ The oil pickup O-ring was never checked or replaced while the oil pan was off. On LS-based engines, a failed pickup O-ring is one of the most common causes of low oil pressure.
❌ An aftermarket oil pan gasket was installed when the OEM gasket is not only superior, but often costs less.
❌ No RTV was applied at the four critical corners where the oil pan meets the timing cover and rear cover, creating a guaranteed leak point.

We corrected everything the right way:
✅ New OEM oil pan gasket
✅ Replaced the cracked oil pickup O-ring
✅ Thoroughly cleaned and degreased the undercarriage
✅ Verified proper oil pressure and leak-free operation

The results speak for themselves:
🔥 Oil pressure increased from a dangerous 5 PSI at hot idle to a healthy 28-30 PSI hot.
🔥 No more leaks.
🔥 One more 6.0L back on the road the way GM intended.

Parts swapping fixes symptoms. Proper diagnosis fixes problems.

This dump trailer has been working hard for a living... and it showed. 💪

Broken door welds. Latching pin snapped clean in half. Years of abuse finally caught up to it.

We got straight to work—cleaned up the damage, plated the weak areas, sleeved the broken components, burned in fresh welds, and finished it off with a little paint to keep it looking right.

No shortcuts. No band-aid fixes. Just a solid repair built to handle the next round of abuse.

Now it's back on the job site doing what it does best. 🔥
