Powertrain & Drivetrain Service
Need drivetrain repair in Thousand Oaks? Your powertrain is everything that moves your vehicle – from the engine to the wheels. At Gallardo's Automotive Service, we diagnose and repair all powertrain components to keep your vehicle delivering reliable power to the road.
What Is the Powertrain?
The powertrain includes all components that generate and deliver power to the wheels:
Traditional Powertrains
- Engine – generates power through combustion
- Transmission – multiplies and distributes engine power
- Driveshaft – transfers power to the axles (RWD/AWD)
- Differential – divides power between wheels and allows turning
- CV axles/Drive axles – deliver power to the wheels
- Transfer case – distributes power in 4WD/AWD vehicles
Hybrid and Electric Powertrains
- Electric motor(s) – provide instant torque
- High-voltage battery pack – stores electrical energy
- Inverter/controller – manages power flow
- Regenerative braking system – recovers energy
Warning Signs of Powertrain Problems
Vibrations
- Vibration at specific speeds – driveshaft or U-joint issue
- Vibration during acceleration – CV axle or engine mount
- Vibration when braking – driveline or brake issue
- Constant vibration – wheel balance or drivetrain wear
Sounds
- Clunking when shifting gears – worn U-joint or motor mount
- Clicking when turning – CV joint failure
- Whining or humming – differential or wheel bearing wear
- Grinding noise – severe wear in driveline components
- Clunk when going from park to drive – worn drivetrain parts
Performance Issues
- Loss of power – engine, transmission, or clutch issue
- Delayed acceleration – transmission slipping or clutch wear
- Vehicle won't move – severe drivetrain failure
- 4WD/AWD not engaging – transfer case or control issue
Warning Lights
- Check engine light – powertrain fault detected
- Transmission warning light
- 4WD/AWD indicator – system malfunction
- Reduced power warning

Frequently Asked Questions
What's the difference between powertrain and drivetrain?
The terms are often used interchangeably, but technically: the powertrain includes everything that creates and delivers power (engine + drivetrain), while the drivetrain refers specifically to the components that deliver power to the wheels (transmission, driveshaft, differential, axles).
How often should differential fluid be changed?
Most manufacturers recommend differential fluid service every 30,000-60,000 miles, or more frequently if you tow, haul heavy loads, or drive in severe conditions.
Why does my 4WD make noise when turning on pavement?
4WD systems designed for off-road use can bind when turning on pavement because all four wheels are locked together. This is normal for part-time 4WD systems and why they should only be used on loose surfaces.
What causes driveshaft vibration?
Common causes include worn U-joints, damaged driveshaft, failed center support bearing, or improper driveline angles (often after lift kits). We can diagnose which component is causing the vibration.
Is a powertrain warranty worth it?
Powertrain repairs can be expensive. If you plan to keep your vehicle long-term, a powertrain warranty can provide valuable peace of mind. We can help you understand what's covered under any warranty you have.
