Truck Repair in Marietta, GA  Pickups, Heavy-Duty, and Fleet Vehicles

Tribble Automotive is one of the few independent shops in the Marietta area that fully services pickup trucks and heavy-duty vehicles with the same level of expertise as passenger cars. Whether you drive a Ford F-150, Chevy Silverado, GMC Sierra, Ram 1500, Toyota Tundra, or a commercial fleet vehicle, our ASE Master Certified technicians are equipped to handle it.

Truck Services We Perform

●     Brake service for trucks and heavy-duty vehicles: Trucks have larger rotors, heavier calipers, and higher load ratings than passenger cars  requiring truck-specific parts and torque specifications. We stock or source components for all major truck platforms.

●     Engine diagnostics for diesel and gasoline trucks: From Ford's 6.7 Power Stroke to GM's Duramax and Ram's Cummins, our diagnostic equipment covers both diesel and gasoline truck engines with manufacturer-specific software.

●     Transmission service for trucks: Truck transmissions handle significantly higher torque loads than passenger car units. We service both automatic and manual truck transmissions, including fluid service, solenoid replacement, and full rebuilds.

●     Cooling system service: Trucks that tow or haul place extreme thermal demands on the cooling system. We perform coolant flushes, thermostat replacement, water pump service, and radiator replacement for all major truck platforms.

●     Fleet accounts available: We work with local businesses operating vehicle fleets in Cobb and Cherokee County. Ask about priority scheduling and consolidated billing for fleet customers.

🚛 Fleet Service Note: If your business operates trucks or a mixed fleet in the Marietta, Kennesaw, or Smyrna area, contact Tribble Automotive to discuss a dedicated fleet service account. We offer priority scheduling and consolidated invoicing for business accounts.

Transmission Repair in Marietta, GA  Diagnosis Before Repair, Every Time

Transmission repair is one of the highest-stakes services in automotive  and one of the most frequently mishandled. At Tribble Automotive, we never recommend transmission work without first performing a complete diagnostic to identify exactly what has failed and why.

Signs Your Transmission Needs Attention

●     Delayed or hard shifting: The transmission hesitates, bangs, or lurches between gears  especially from 1st to 2nd, or at highway cruising speed.

●     Slipping gears: The engine revs but the vehicle doesn't accelerate proportionally  the transmission is slipping out of gear under load.

●     Check Engine Light with shifting symptoms: Transmission fault codes (P0700–P0799) often appear before drivability symptoms are severe enough to notice.

●     Burning smell from fluid: Dark, burnt-smelling transmission fluid is a sign the fluid has degraded and is causing accelerated internal wear.

●     Fluid leak under the vehicle: Transmission fluid is typically red or pink. A leak under the center of the vehicle often points to transmission pan gasket, cooler line, or front seal failure.

Transmission Services at Tribble Automotive

●     Automatic transmission fluid flush and filter replacement  $150–$280

●     Transmission diagnostic scan and road test  $80–$150

●     Solenoid and sensor replacement  $200–$600

●     Torque converter replacement  $600–$1,200

●     Full automatic transmission rebuild  $1,800–$3,500

●     Manual transmission clutch replacement  $800–$2,000

Engine Diagnostics in Marietta, GA  Professional Pinpoint Testing, Not Guesswork

When your Check Engine Light turns on, a dashboard warning appears, or your vehicle simply isn't running the way it should, professional engine diagnostics is the only reliable way to find out what's actually wrong. At Tribble Automotive, our diagnostic process goes far beyond what a free parts-store code scan provides:

●     OBD-II trouble code retrieval: We pull all stored and pending fault codes from every module in the vehicle  engine, transmission, ABS, airbag, and body control.

●     Live data analysis: We monitor real-time sensor readings while the vehicle is running to identify sensors performing outside of normal parameters.

●     Oscilloscope waveform testing: For intermittent faults and electrical issues, oscilloscope analysis catches signal irregularities that a basic code scanner misses entirely.

●     Smoke machine vacuum leak testing: For lean codes and rough idle complaints, we pressurize the intake and use smoke to locate every vacuum leak with precision.

●     Fuel system pressure testing: We test fuel pump output pressure and injector performance to confirm fuel delivery is within manufacturer specification.

●     Written estimate before work begins: Every diagnosis concludes with a plain-English explanation of what we found, what it will cost to fix, and what happens if it's left unaddressed.

🔧 Diagnostic Cost: A comprehensive engine diagnostic at Tribble Automotive typically costs $80–$150 depending on system complexity. This fee is applied toward the repair if the work is performed with us. Accurate diagnosis the first time prevents expensive trial-and-error parts replacement.

Tire Rotation and Wheel Alignment in Marietta, GA

Tire rotation and wheel alignment are among the most cost-effective maintenance services a vehicle owner can invest in  and among the most frequently skipped. At Tribble Automotive, we include a complimentary multi-point inspection with every tire rotation to catch developing issues while the vehicle is already on the lift.

Tire Rotation  Why It Matters

Front tires wear significantly faster than rear tires on most front-wheel-drive vehicles  often 30–40% faster due to steering load. Rotating tires every 5,000–7,500 miles evens out this wear pattern, extending the life of your full tire set by 15,000–25,000 miles. That's a real saving of $400–$800 in tire replacement costs over the life of the vehicle.

●     Rotation patterns: We follow the manufacturer-recommended rotation pattern for your specific drivetrain  front-wheel-drive, rear-wheel-drive, all-wheel-drive, and directional tire patterns all require different approaches.

●     What's included: All four tires rotated, torqued to manufacturer specification, and tire pressure set to the vehicle's door-jamb spec. Complimentary multi-point inspection included.

●     Cost: $40–$70 at Tribble Automotive.

Wheel Alignment  Why It Matters

Your vehicle's wheels need to point in precisely the correct direction  both horizontally (toe) and vertically (camber)  to drive straight, wear tires evenly, and handle predictably. Marietta's pothole-heavy surface streets, road construction zones on I-75 and I-575, and kerb strikes from parking all knock alignment out of spec.

●     Signs you need an alignment: Vehicle pulls left or right on a straight road; steering wheel is off-center when driving straight; tires wearing unevenly on inside or outside edge.

●     What's included: Computerized 4-wheel alignment measurement and adjustment of toe, camber, and caster angles to manufacturer specification. Printed before/after alignment report provided.

●     Cost: $80–$150 for 4-wheel computerized alignment.

●     When to align: After any suspension component replacement, after hitting a significant pothole or kerb, and every 12 months or 15,000 miles as preventive maintenance.
