We help you maintain consistent performance, cleaner emissions, and longer engine life.
Turbocharger and Air System Repair
Your turbocharger gives your diesel the power and torque it’s known for — but when it starts to fail, you’ll notice right away. Whistling noises, black smoke, or sluggish acceleration are all signs that your turbo needs attention.
Turbo services at our Monroe location include:
- Turbocharger diagnostics and replacement

- Intercooler and piping service
We’ll restore your turbo’s power and performance so your diesel delivers the smooth acceleration you expect.
EGR, DPF, and DEF System Maintenance
Modern diesel vehicles are equipped with advanced emissions systems that help reduce environmental impact — but they require regular service to work properly. Our Monroe shop specializes in cleaning and maintaining these systems to prevent costly breakdowns.
We provide:
- DPF cleaning and regeneration
- EGR valve replacement and service
- DEF system diagnostics and maintenance
- Sensor inspection and recalibration
Keeping these systems clean improves fuel efficiency, prevents warning lights, and ensures your truck passes emissions testing.
Transmission and Drivetrain Repair
Diesel trucks are built to handle serious power and heavy towing, which means their transmissions and drivetrains take a beating. Our experts offer full transmission service to help your truck handle that power efficiently.
We handle:
- Transmission fluid changes and flushes
- Clutch and flywheel replacement
- Transfer case and differential repair
- Driveshaft and axle inspections
We’ll make sure your truck shifts smoothly, delivers power evenly, and stays ready for the next haul.
Diesel Cooling System Service
Diesel engines generate significant heat under pressure. That’s why cooling system maintenance is essential for avoiding overheating and engine damage.
Cooling system services include:
- Radiator inspection and replacement
- Coolant flush and refill
- Thermostat and water pump repair
- Hose and gasket checks
- Fan clutch service
If your diesel is running hotter than normal or losing coolant, don’t wait — our Monroe team can help before the problem worsens.
