Powertrain System

What It Does

The powertrain includes the engine, transmission ("transaxle" on front-wheel-drive vehicles) and drive axles that work in tandem to move the vehicle.

Service and Maintenance

While many of your vehicle's powertrain components such as the driveshaft and axle shafts don't require much routine maintenance, as shown below, there are a few parts that need periodic attention.

Check the engine oil level at every fuel fill and add oil if necessary
About once a month, make sure all tires are inflated properly and check for any unusual wear or damage
Have an underbody flushing performed approximately once a year
The engine's exterior should be cleaned periodically. Buildups of oil and dirt can cause the engine to run hot or hide leaks
Have your vehicle inspected if the "Service Engine Soon" light illuminates

Did You Know?

You vehicle's differential is a kind of "unsung hero" within the powertrain system.

The differential has two primary responsibilities: directing engine power to the drive wheels and allowing the wheels to rotate at different speeds when cornering. If the wheels couldn't rotate at different speeds, your vehicle's tires would display a wheel "hop" effect, thereby making cornering a rough experience for both you and your tires.

So, don't be "indifferent" toward your differential. It plays a vital role in moving your vehicle and ensuring a smooth ride.

Radiator Contamination

When an engine or transmission fails and needs to be replaced, often, the vehicle's radiator must a replaced as well. This is due to the engine or transmission contaminating the radiator with excessive gear shavings or other foreign objects at failure.

1 Engine

Function:
As the heart of the vehicle, then engine uses internal combustion energy (the igniting of fuel and air) to send power through the transmission or transaxle to the wheels.
Signs of Wear:
Rough-running engine, high oil and/or fuel consumption, visible oil smoke while engine is running.

 

2 Powertrain Control Module (PCM)

Function:
Monitors and controls the operation of the ignition, emission, fuel injection and automatic transmission systems.
Signs of Wear:
Engine won't start, reduced or loss of engine power, erratic transmission operation.
