Powertrain Maintenance and Repair


At HB Auto & AC, located on Autopark dr. in Huntington Beach, we know all too well about the importance of regular powertrain maintenance and repair. We only employ certified mechanics with a wealth of experience who understand common faults and how to spot issues before they become too severe. The powertrain is crucial to maintaining power, safety and the longevity of your vehicle. So, get in touch with us as soon as possible to get a full assessment and advice on any essential powertrain repairs.

What is the powertrain?

The powertrain system on your vehicle consists of the transmission, internal combustion engine, and axle assembly. The system is controlled by the onboard computer, and in front-wheel-drive cars, the transmission and differential get combined into a transaxle.

Why is powertrain maintenance important?

Regular powertrain maintenance will benefit drivers in many different ways. Firstly, it’s vital to note that you could extend the life of components used on your vehicle. You will also help to boost performance, increase power, and reduce your oil consumption. Our expert services will ensure your vehicle benefits from a quiet operation, low emissions, and improved fuel economy.

What is the internal combustion engine?

Engine The internal combustion engine in your vehicle converts chemical energy in the form of gas into kinetic energy, thus enabling your car to move on the road. It turns the crankshaft and flywheel, and there are many different components including:

  • Cylinder blocks
  • Cylinder heads
  • Intake and exhaust valves
  • Pistons and piston rings
  • Crankshafts
  • Oil pans
  • Sealing gaskets

During the repair and maintenance service our team performs, we’ll check every element of the engine to ensure there are no hidden issues affecting the performance of your car or truck.

When do I need powertrain maintenance and repair?

Different elements of the powertrain have different lifespans. For that reason, it’s sensible to arrange a maintenance and repair booking whenever you notice a problem. At most, you should get in touch with our team and come to see us every 5,000 to 10,000 miles depending on the year or make of your vehicle.

What are the common symptoms I should consider?

There are many telltale signs drivers might notice that should encourage them to contact us for powertrain maintenance and repair. Here is some information that should help to shed light on the subject.

Internal combustion engine symptoms

Lots of motorists report a deep or shallow knocking noise when they come to see our team. That is often a sign of a malfunctioning internal combustion engine. There is usually tailpipe smoke too, and sometimes the engine can overheat. High oil consumption should start alarm bells ringing, as should any leaks or unusual exhaust emissions. If you notice any of those issues, or your check engine light is on, do not hesitate to get in touch and organize an appointment with one of our dedicated and skilled mechanics.

Transmission symptoms

Transmission symptoms are often a little more challenging to identify, but drivers tend to notice a grinding feeling when they move between gears. In the worst situations, gears will slip or fail altogether making the car exceptionally dangerous for the motorist and other road users. Sometimes cars will even refuse to move, regardless of whether you manage to hit the right gear or not. Again, if you’re concerned about any faults that might relate to your transmission, just come to see us for a full powertrain assessment and transmission repair.

Differential or axle symptom

The differentials connect the transmission to the wheels on your vehicle. Things can go wrong from time to time, and that’s why you need to see a specialist mechanic if you notice any strange whining or growling noises. Once you arrive at our premises, we’ll check the casing, gears, and clutches to identify the problem and find the perfect solution straight away. Differentials are a crucial part of the powertrain system, and our team uses all the best strategies and assessment techniques to solve the problem as quickly and cost efficiently as possible.
