Brake pads are the friction components in your vehicle’s disc braking system. They press against the rotors to convert kinetic energy into heat, bringing your car to a controlled stop. As a wear-and-tear item, they are designed to degrade over time. Exactly how long they last depends on material composition, driving habits, vehicle weight, and…
A transmission cooler is a heat exchanger. It regulates the operating temperature of automatic transmission fluid (ATF). The fluid runs through a finned, radiator-style core. Engine coolant or ambient air absorbs excess heat before the fluid returns to the gearbox. This auxiliary cooling system sits between the torque converter and the internal oil pump. It…
The Continuously Variable Transmission, or CVT, is a type of automatic transmission that eschews fixed gear ratios in favor of a seamless, stepless power delivery system. Unlike a traditional automatic with planetary gearsets or a manual with a clutch, a CVT typically relies on a steel belt or chain running between two variable-diameter pulleys. This…
CVT Maintenance Guide: Extend Transmission Life with These 7 Essential Service Steps The continuously variable transmission (CVT) is a type of automatic transmission. It uses a belt-and-pulley system instead of fixed gears to deliver seamless power. Unlike conventional automatics with discrete gear ratios, the CVT keeps the engine at its most efficient RPM. The pulleys…
A transmission mount is a mechanical component that secures the gearbox to the vehicle’s chassis or subframe, acting as the structural bridge between the drivetrain and the body. It is typically constructed from a metal bracket bonded to a rubber or polyurethane bushing, designed to absorb torsional forces and dampen vibrations generated by the engine…
Differential fluid is the specialized gear oil that lubricates the gears, bearings, and clutch packs inside your vehicle’s differential—the mechanical component that allows your wheels to rotate at different speeds when cornering. Unlike engine oil, which circulates through a pressurized system, differential fluid operates in a splash-lubrication environment, enduring extreme shear forces, high temperatures, and…
Transmission additives are chemical compounds designed to modify the properties of automatic transmission fluid (ATF) or manual gearbox oil. These products fall into two broad categories: friction modifiers that alter shift feel, and seal conditioners that rejuvenate aged rubber gaskets. Unlike a fluid change, which replaces the entire lubricant volume, an additive works as a…
The throwout bearing — also called a release bearing — is the small but critical hydraulic or mechanical component that disengages your clutch when you press the pedal. It sits at the input shaft of the transmission, riding on the clutch fork, and its job is simple: press against the diaphragm spring fingers to break…
The drivetrain is the mechanical system that transfers power from your engine to the road, and choosing between AWD vs 4WD is one of the most consequential decisions you will make when buying a vehicle. All-wheel drive (AWD) systems use a center differential to distribute torque between both axles automatically, while four-wheel drive (4WD) systems…
Conventional motor oil is a petroleum-based lubricant. It has protected internal combustion engines for over a century. Unlike synthetic oils, which are chemically engineered in laboratories, conventional oil is refined directly from crude petroleum. It is fortified with additive packages to reduce friction, control deposits, and resist thermal breakdown. It remains the default choice for…
