What does flushing a transmission do?
A Transmission Flush is an oil change process in which all oil from a transmission has been removed. New oil (and sometimes cleaning products) are run through the transmission using a special machine to push away sludge and grime. Then, it is filled with new oil.
Are transmission flushes also really necessary?
A flush is not necessary for 46K miles under normal driving conditions. They make a lot of money selling flushes and that's why they are recommended. Most transmissions last 100,000 miles before they need to be maintained.
How long does it take for a transmission to be flushed? It takes between 3 and 4 hours.
Also, flushing a transmission can cause problems?
Let's face it, flushing the transmission fluid will not fix any existing transmission problems. If your transmission is making grinding or erratic shifts, it may be already damaged. Flushing the fluid will not prevent transmission failure.
What happens if you don't change your transmission fluid?
What happens if I don't change my transmission fluid when it is suggested? The transmission fluid can run low and cause your transmission not to shift properly or at all. It can also cause damage to the transmission's internal parts, which won't be properly lubricated.

Should I change transmission fluid after 200k miles?

Is it bad to change transmission fluid on high mileage?

What happens if your transmission fluid is dirty?
Why dirty transmission fluid is bad
When your vehicle's transmission fluid is riddled with pieces of metal, it wears down the parts of your transmission at a faster-than-normal rate. And if the fluid is overly dirty and contaminated, the transmission cannot build up enough hydraulic pressure to properly shift gears.How do you know when you need transmission fluid?
How Do I Tell If My Transmission Fluid Is Bad? Things such as trouble going into gear, hard shifts or thumps between gears, slipping or jumping gears, delay in acceleration, and strange noises such as whining or grinding are all signs it's time to change the transmission fluid.
Should I change transmission fluid after 100k miles?
How Often to Change Transmission Fluid? As a general rule fluids should be changed on or before 100k miles. It's generally easy to perform yourself, which will prolong the operating life of your transmission and be cheaper than replacing it when it fails.
Can you change transmission fluid after 200000 miles?
At 200k miles it is entirely possible the tranny fluid has a bunch of the friction material in it that helps ensure your transmission still works. Drain the fluid and you may lose that friction material.
Is flushing the transmission Good or bad?
A transmission flush is a perfectly safe service for your car, and is worth the extra money it costs. Transmission flushes have a bad rap however as some people expect a flush to fix major problems, such as slipping and stalling.
What will flushing your transmission do?

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.
How many times drain and fill Transmission?
Drain and fill 3 times and drive at least 1000 miles in between drain and fill.
Can a clogged transmission filter cause shifting problems?
When the fluid level is low, it can lead to shifting problems. As well, transmission fluid that has become oxidized (burnt) or dirty can also create shifting problems. Next, if the transmission filter is clogged that can also lead to difficult, uneven shifts – but a fluid and filter change should correct this.
Does changing transmission fluid help shifting?
If you catch a shifting issue very early, a transmission fluid flush can sometimes fix shifting issues. The fresh fluid helps clutch discs and steel discs bond and hold without slipping. The seal conditioners in the new fluid help soften the clutch piston lip seals so they seal better.
Can you flush a torque converter?
And any dirt particles that are in the fluid get flung out until they collect around this outside area of the torque converter. Now unless you flush, there's no way to ever clean that away.
What does it mean when your transmission fluid is brown?
Is Transmission Fluid Dark Brown? Cloudy, dark brown transmission fluid means it is old and contaminated. It's likely no longer able to provide adequate lubrication which puts your transmission at risk for wear and damage to internal components.
How do you inspect a transmission?
To do this on your own, start your car and put it in park. Open the hood and locate the area where the transmission fluid is stored; then pull out the dipstick that covers it. Make sure the transmission fluid is at the right level, and then check the color. Clean fluid should be reddish and almost translucent.
