  • Manual Transmission
    A manual transmission, also known as manual gearbox, standard transmission, or stick shift, is a multi-speed motor vehicle transmission system
  • CVT Transmission
    A continuously variable transmission is an automated transmission that can change through a continuous range of gear ratios.
  • Automated Manual Transmission
    AMT functions similarly to an automatic, except that the driver can leave the clutch work to the computer when they desire


A Transmission, often known as a gearbox, serves as the conduit through which engine power is transferred mechanically through gears and gear trains to the wheels. Without a transmission, a person cannot apply force to a vehicle in a controlled manner; otherwise, the automobile cannot move. The car's gearbox, which transforms the engine's power into something the vehicle can utilize, is known as the transmission. Simply put, without it, you would be driving aimlessly in your car with the motor running.

What Does A Transmission Do?

Any motor vehicle must have a transmission to keep the engine from self-destructing. Without a gearbox system, automobile engines would spin too rapidly for structural stability, which would cause the majority of engines to break apart or overheat. Additionally, any vehicle lacking a transmission would be unable to use the engine's speed, limiting the vehicle's top speed.

Types of Transmissions

There are two types of transmissions: manual and automatic. However, there are other varieties of automatic transmissions, including automatic, continuously variable, semi-automatic, Tiptronic, and dual-clutch.

Automatic Transmissions: The process that drives a manual gearbox happens outside of an Automatic Transmission, which is the major distinction between an automatic and manual transmission. Clutches are often not used in automatic gearboxes. Instead, a torque converter is used by the automatic gearbox to shift ratios.

Since the early 1900s, there has been some variation of the first automatic gearbox, which was more akin to a semi-automatic transmission because it still featured a clutch. The Hydro-Matic in a 1939 Oldsmobile for the 1940 model year was the first accurate automatic transmission to be installed in a production vehicle. Earl Avery Thompson created the invention.

Large vehicles and SUVs often use conventional automatic gearboxes. Here are a few words that are frequently used in relation to automatic gearboxes.

Manual Transmission: The driver of a manual gearbox must choose the appropriate gear and engage or release the clutch. The clutch, pressure plate, and flywheel of the transmission are used to engage and disengage the engine.

The engine is linked to the pressure plate and flywheel. They are separated by the clutch and splined into the transmission input shaft. The pressure plate is released when you "push in the clutch," which separates the clutch from the engine. Every time you shift, you must first depress the clutch.

CVT Transmissions: The primary difference between an automatic and manual gearbox is that with an automatic transmission, the mechanism that drives a manual transmission is located inside the transmission itself. Normally, clutches are not used in automatic gearboxes. On the other hand, the automatic transmission uses a torque converter to shift ratios. The earliest automatic gearbox, which featured a clutch and was more like a semi-automatic transmission, has existed in some form since the early 1900s. The Hydro-Matic was the first real automatic gearbox to be utilized in a production vehicle, and it was installed in a 1939 Oldsmobile for the 1940 model year. Earl Avery Thompson was the creator.

Traditional automatic gearboxes are used in most significant SUVs and trucks. Here are some words frequently used in connection with automatic transmissions.

Dual-Clutch Transmissions: There are two clutches in this transmission, and they can be wet or dry. The even gears are operated by one clutch (2, 4, and 6). The second clutch shifts the unusual gears (1, 3, 5, and reverse). Older automobiles frequently used dual-clutch gearboxes, and they are still used in contemporary race cars. Modern dual-clutch automated manual gearboxes, also known as double-clutch or twin-clutch transmissions, bridge the gap between a manual and automatic transmission by using a computer to regulate clutch engagement and shifting.

Tiptronic transmission: An automatic transmission with a Tiptronic gearbox enables manual shifts using the shifter and steering wheel controls. The disadvantage is that if the Transmission deviates from the predetermined limits, the computer will overrule or refuse to enable manual mode.

Semi-Automatic Transmissions: You may choose between manual and automatic modes on a semi-automatic. You may either use a lever on the gearstick or utilize steering wheel paddles that enable you to shift up or down by merely pushing the "+" or "-" button, as opposed to utilizing the clutch pedal and changing gears with your foot.

Remanufactured Transmissions for Sale

Remanufactured transmissions are a great alternative to buying a brand-new one. They can be cheaper, have a better warranty, and have the ability to be tested. When you buy a remanufactured transmission, you know exactly what kind of labor has been used to make it. You are also guaranteed its quality. Remanufacturing is a process where the transmission is completely disassembled and inspected. Every component is checked for quality and functionality. If a part doesn't meet the original specifications, it is replaced with a new one.

Once the remanufactured transmission is complete, it is shipped to the original manufacturer. Then, it is put on a dyno machine to test its performance. This simulates real-world driving conditions, and it reveals any problems before they are used. Remanufacturing is performed by experts. These professionals work with a team to rebuild the transmission. During the build, skilled mechanics work to prevent transmission problems. A remanufactured transmission is as close to new as possible. All components are thoroughly inspected, and the surfaces of the transmission are machined to the factory's specifications.

Buy Auto Part is a company with experience of more than one decade in the automotive industry dedicated to providing affordable Reman Transmission without compromising on quality.
