What is a Transmission?
The transmission is a crucial component of any vehicle, responsible for transferring power from the engine to the wheels. It ensures that the engine operates within its optimal range, regardless of the speed at which the vehicle is traveling. There are two main types of transmissions found in vehicles: automatic and manual.
Automatic transmissions manage gear shifts for the driver, providing a seamless driving experience. They are equipped with a torque converter that connects the engine with the transmission. Manual transmissions, on the other hand, require the driver to manually shift gears using a clutch and gear stick. Both types have their pros and cons, but they serve the same fundamental purpose.

This process involves a complex system of gears, clutches, and fluid that work in harmony to ensure smooth operation.
When a car accelerates, the transmission shifts through different gears to optimize the engine's performance. In an automatic transmission, this process is controlled by a hydraulic system and electronic sensors that determine the appropriate gear based on speed and load. In contrast, a manual transmission relies on the driver's input to change gears at the right time.
The transmission fluid plays a vital role in maintaining the system's functionality. It lubricates the moving parts, cools the transmission, and ensures that the hydraulic system operates efficiently. Any disruption in these processes can lead to transmission issues, making it important to recognize and address them promptly.
