Engine & Transmission Repair
Accurate Diagnosis. Expert Repairs. Long-Term Reliability.
At Tribble Automotive, our ASE Master Certified technicians have been diagnosing and repairing engines and transmissions for drivers across Marietta, East Cobb, Kennesaw, Woodstock, and Roswell for over 27 years. We use advanced diagnostic equipment and manufacturer-level procedures not guesswork to find the real problem before recommending any repair.
Engine Repair
Modern engines are interdependent systems. One failing component can quietly stress the ones around it.
We diagnose and repair:
-
Check Engine Light concerns
-
Misfires, rough idle, and stalling
-
Oil and coolant leaks
-
Cooling system failures water pump, thermostat
-
Timing chain issues
-
Fuel and ignition system problems
-
Sensor failures
-
Loss of power and acceleration
If your Check Engine Light is on, don't wait. Some causes are minor. Others aren't. A fast diagnostic tells you exactly which.
Transmission Repair
Your transmission transfers engine power to the wheels. When it starts to slip, hesitate, or grind, the window for a straightforward repair closes quickly. We service both automatic and manual transmissions across a wide range of domestic and import vehicles.
We diagnose and repair:
-
Delayed or hard shifting
-
Slipping gears
-
Transmission fluid leaks and overheating
-
Grinding, whining, or shuddering
-
Torque converter and solenoid failures
-
Clutch issues
-
Transmission warning lights
Catching a transmission problem early is almost always the difference between a fluid service and a full rebuild.
Warning Signs to Watch For
Engine: Rough idle, poor fuel economy, excessive exhaust smoke, knocking or ticking noises, overheating, loss of power.
Transmission: Hesitation when shifting, slipping gears, burning smell, fluid spots under your vehicle, unusual vibrations.
If you're noticing any of these, book an inspection. The longer it runs, the more it costs.

Common Questions
How do I know if my transmission is failing? Slipping gears, delayed shifting, fluid leaks, unusual noises, or hesitation during acceleration are the most common signs. A diagnostic inspection gives you a definitive answer.
Can I keep driving with the Check Engine Light on? Sometimes yes, sometimes no, it depends entirely on the cause. A quick diagnostic removes the uncertainty and protects you from turning a small issue into a big one.
Is routine transmission service worth it? Yes. It's far cheaper than the repairs skipping it leads to.
What causes engine power loss? Ignition issues, fuel delivery problems, sensor failures, airflow restrictions, or internal engine wear, diagnostics identify which
