Transmission Fluid Cooler

Certain models are equipped with a separate cooler that regulates the temperature of the transmission fluid to improve the longevity and performance of the transmission itself.

Torque Converter

This component is responsible for transferring power from the transmission to the engine of an automatic transmission. It consists of a turbine, stator, and pump.


The clutch serves the purpose of disengaging and engaging the transmission from the engine when the driver changes gears in a vehicle with a manual transmission.

Brake System

Our auto repair professionals encounter many vehicles with brake issues because each component of the brake system is subject to continuous use and, therefore, a significant amount of wear and tear.

ABS (Anti-Lock Braking System) Module

This component stops the wheels from locking up when the brakes are pressed hard. The purpose of this system is to reduce and control stopping distances.

Brake Hoses and Lines

These tubes move brake fluid between the brake calipers and master cylinder to allow for appropriate distribution of braking force.

Brake Drums and Rotors/Discs

Drum brakes use a drum and brake shoes to slow and/or stop the vehicle. When the driver presses the brake pedal, hydraulic pressure presses the brake shoes against the drum, which creates friction and slows the wheels. Discs or rotors are a different type of system, most often found in modern cars. They feature round, flat, metal discs attached to a wheel hub. Brake pads push against the rotors when the brake is pressed, which generates friction and decelerates the car.

Master Cylinder

Using hydraulic power, the brake master cylinder propels pressurized fluid through brake lines, initiating the action of brake calipers and regulating the intensity of braking force applied to the wheels.

Brake Calipers

Brake calipers encase the brake pads and exert force onto the brake discs, initiating friction that stops the rotation of the wheels to bring the vehicle to a stop.

Brake Pads

When the brake system is engaged, brake pads utilize friction against either the brake discs or drums to transform the vehicle’s kinetic energy into heat, effectively reducing its speed or bringing it to a complete stop. These crucial components are commonly crafted from friction-based materials to optimize braking performance.


Our local automotive shop often works on drivetrains because they are intricate systems responsible for transmitting power from the engine to the wheels. They require regular maintenance and occasional repairs to ensure smooth operation and optimal vehicle performance.
