If you do a flush when there is damaged transmission material in the transmission fluid, you could cause a problem in the valve body at the bottom of the transmission. If the valve body gets gunked up with damaged transmission material, you could lose the ability to shift between gears.Simply so, are transmission flushes really necessary?
Under normal driving conditions, a flush is NOT necessary at 46K miles. The shops make money on flushes, that's why they recommend them. Most transmissions are good for 100,000 miles before requiring maintenance.
One may also ask, when should you not change transmission fluid? Manual: Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles. Automatic: Service intervals for an automatic transmission vary from every 30,000 miles to never.
In this way, is it safe to change transmission fluid on high mileage?

Should I change transmission fluid after 200k miles?
The manufacturer's maintenance schedule for many automatic transmissions doesn't call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and that it should be done at least every 50,000 miles.Why You Should Never flush your transmission fluid?
Pressure flushing can cause aging seals to start leaking. When it leaks more than a quart it could burn up the unit. Flushing does not cause the transmission to fail but it may speed up the process because it pushed metal particles back through the system.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.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.How do I know if I need a transmission flush?

How much should a transmission flush cost?
Average Cost and Factors The typical price range for a transmission flush is $125 to $250 – approximately twice as much as a fluid change due to the additional fluid required (12-22 quarts instead of 5-7 quarts) to completely replace the old fluid. The average you can expect to pay is $150 for the full service.What is the difference between Flushing and draining a transmission?
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. While it depends how often you should have your transmission serviced, it also matters which service you choose.What happens if you have too much transmission fluid?
The proper amount of fluid also keeps a constant level of pressure inside the transmission. However, when you have too much transmission fluid, the pressure builds within the transmission. This grinding will wear down the gears and make it difficult for the transmission to shift without a delay.How do you flush a transmission?
Disconnect the hose that returns the transmission fluid from the cooler and place the end into a bucket full of fresh transmission fluid. Start the car and run the transmission back and forth through the gears a few times until the fluid coming out of the transmission looks clean or you are nearly out of fresh fluid.Should I change brown transmission fluid?

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 I flush my own transmission?
» A transmission flush can be performed (DIY) using the transmission's pump without a flush machine. 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.
