Is transmission flush worth it?
Some mechanics say a flush can prolong the life of the transmission. If the transmission is slipping, making a grinding noise, or there's a lag in acceleration after applying the gas, it could be an indication that the vehicle is low on transmission fluid or could be in need of a flush.
Are transmission flushes worth it?
A transmission flush usually costs twice as much as a transmission fluid change because it uses more fluid to replace the old one. According to estimates, the additional transmission fluid required for flushing ranges from 384 to 704 ounces (around 12 to 22 quarts). Whatever the price might be, a transmission fluid flush is worth it.
How often should you do a transmission flush?

Does transmission fluid wear out?
Basically, transmission fluid acts as a lubricant and coolant, and ensures that various components of the transmission system are not subjected to rigorous wear and tear. Over a period, this fluid starts wearing out and you are expected to replace it with new fluid. Some experts are of the opinion that even though transmission fluid change is a beneficial, it fails to get rid of the residue left by the old fluid. This residue, which consists of traces of bad fluid, corroded particles, etc., contaminates the new fluid and spoils it in a relatively shorter span of time.
Does flushing out old fluid damage the internal components?
They argue that the excessive pressure used to flush out older fluid has the tendency to damage the internal components of the system. It does help in getting rid of contaminants to some extent, but whether it really gets rid of all the contaminants is again a subject of debate.
Is It Good for the Vehicle?
Auto experts seem divided over this concept. While those in its favor argue that it is a healthy practice when undertaken once in a while, critics seem least impressed. Whilst refuting these claims, critics of the practice state that a high pressure flu sh of transmission fluid is in fact harmful for the vehicle as it gives rise to several problems. They argue that the excessive pressure used to flush out older fluid has the tendency to damage the internal components of the system.

Will a Transmission Flush Hurt My Car?
A transmission flush won’t hurt your car if the service is done right. Some say that it is a 100% safe procedure. Most automakers recommend a transmission flush every two years or 30,000 miles. However, some carmakers believe that it should not be this frequent. They say you should flush only every 6 1/2 years or 100,000 miles.
Why is a Transmission Flush Required?
They’ll remove the oil pan bolt, remove the oil filter, and let the old fluid drain until it stops flowing. However, it doesn’t fully remove all of the engine oil. Inside the engine block and cylinder heads are a series of galleys that keep a small portion of oil to lubricate moving parts until the new oil is circulated through the engine. An automatic transmission’s fluid is kept inside the hydraulic lines, so it needs to be ‘flushed’ or pushed through the lines to drain effectively. This also serves a secondary purpose. The transmission flush also pushes debris and other small particles that develop from the transmission filter’s worn out fibers.
Why do you need to change transmission fluid?
Here are 4 reasons why this process is so important for those with automatic transmissions: 1 It extends the transmission lifespan: If the transmission’s internal hydraulic lines are clogged, it can cause inner seals to break, which creates internal leaks and can lead to complete transmission failure. By having the fluid flushed and filters replaced every 30,000 to 50,000 miles, you significantly reduce the potential of damage and can extend its lifespan. 2 It improves smooth shifting: When transmission fluid is replaced and the fluid is flushed, it improves the efficient flow of transmission fluid throughout the system. The end result is that the transmission will shift smoother. 3 It is vital to protect warranties: Most new cars, trucks, and SUVs come with a powertrain warranty — which protects the engine, transmission and drive-system components. However, if those systems are not maintained as recommended, it can void most extended warranties and cost you a significant amount of money if you need to replace them. 4 It can improve fuel economy: A smooth-shifting transmission is also critical for the efficient operation of your engine. If the transmission slips or shifts higher than the engine is set, it can and often will burn more fuel inside the engine than it should. A transmission fluid change can contribute to optimal fuel mileage.
How does automatic transmission work?
Simply put, an automatic transmission is a hydraulic system that relies on a consistent flow of transmission fluid levels to supply hydraulic pressure in order to operate. Transmission fluid is different than engine oil — it is designed with a specific viscosity and a combination of additives that help reduce expansion as the fluid is heated. This keeps the vehicle's transmission fluid consistent, which permits it to flow efficiently through each hydraulic line inside the transmission. Over time and with continued use, the additives will begin to wear out, which causes the fluid to thin and become more susceptible to expansion due to heat. Dirty transmission fluid needs to be replaced with new fluid for ideal performance.
Why is a smooth shifting transmission important?
If the transmission slips or shifts higher than the engine is set , it can and often will burn more fuel inside the engine than it should. A transmission fluid change can contribute to optimal fuel mileage.
Do CVT transmissions need flushes?
You’ll notice in the information above that we haven’t mentioned transmission flushes for CV T or manual transmissions. These units operate differently and have their own recommended service intervals. The best way to clarify what you should have done for your vehicle is to contact a professional mechanic, your automotive dealership or investigate your owner’s manual for a transmission service maintenance schedule. This will tell you when all the recommended services are required and suggested to keep your vehicle running strong and protect those warranties.
What is a transmission flush?
A transmission flush is a procedure to remove old automatic transmission fluid (ATF), sludge and grime from a vehicle’s transmission and replace it with fresh fluid. The purpose of ATF is to cool and lubricate your automatic transmission. Over time, transmission fluid collects foreign particles that can interfere with these functions -- causing your transmission to generate more friction and heat. Eventually these particles can build up into sludge deposits in your transmission and interfere with shifting and acceleration.
How long does it take to flush a transmission?
A trained mechanic can perform a simple transmission flush in three to four hours using a commercial flushing machine or pump inlet. A transmission fluid change takes just about 30 minutes.
