what is a automatic transmission flush?
325445
A transmission flush is a process in which the fluid in an automatic transmission is flushed out of the transmission and replaced with new ATF. The flushing process, when done correctly, replaces nearly 100% of the old fluid with new fluid, including fluid in the torque converter and oil cooler lines.

A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission or double-clutch transmission) is a type of automatic transmission in automobiles, closely related to a manual transmission. It uses two separate clutches for odd and even gear sets.

Operation of an Automatic Transmission The most common type of automatic transmission uses hydraulic power to shift gears. ... As the engine transmits power to the pump of the torque converter, the pump converts this power into transmission fluid that powers the turbine of the torque converter.

Hydraulic automatic transmissions. The predominant form of the automatic transmission is hydraulically operated; using a fluid coupling or torque converter, and a set of planetary gearsets to provide a range of gear ratios.

It needs to be done correctly to ensure the result you want. If it's done correctly, a transmission flush will not harm your car, however. If it's necessary, it will improve the overall function of your transmission and will be a benefit to the longevity of your vehicle.

It drains the old fluid and holds it inside the machine while replenishing the transmission with new fluid. Unlike a simple pan drop, a flushing machine removes just about all the old fluid, including the fluid inside the torque converter.

The most common type of automatic transmission uses hydraulic power to shift gears. According to How Stuff Works, this device combines a torque or fluid coupling converter with gearsets that provide the desired range of gears for the vehicle.

Many manufacturers recommend a transmission flush every 30,000 miles or 2 years. However, not all recommend this frequently – some suggest a flush only every 100,000 miles, and others don't recommend a transmission flush at all.

Low Transmission Fluid There is a common theme amongst the issues that cause problems for automatic transmissions, and it is the fact that there isn't enough automatic transmission fluid flowing through the mechanism.

As you can tell by their names, a transmission flush and a fluid change are two completely different services. While a transmission fluid change focuses on draining the dirty fluid from the pan, a transmission flush gets rids of all the fluid in the pan, the cooler lines, as well as the torque converter.

In an automatic transmission, the car decides when you shift and automatically changes gears for you. In a manual transmission car, you are responsible for shifting gears using the clutch and gas pedals.

Purpose of an Automatic Transmission. Location of the automatic transmission. Just like that of a manual transmission, the automatic transmission's primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds.

Flushing does not cause the transmission to fail but it may speed up the process because it pushed metal particles back through the system. So if I shouldn't flush – what should I do? Keeping your fluid fresh lengthens its life. Vehicles vary – some have filters, screens, internal filters, etc.

In automatic transmissions/transaxles, the recommended service interval is about every 30,000 miles or 30 months. (Check your owner's manual or service manual for your car's specifics.) The automatic transmission fluid (ATF) should be changed sooner if its dipstick reveals dark or burnt-smelling fluid.
