Is there any truth about changing transmission fluid?
The usual story is something along the lines of “older American make care with 200,000 miles, a week after we changed the fluid, the transmission went out.” Is there any truth to this?
How much fluid does a transmission pan drop change?
The debate about transmission fluid change revolves around a basic problem. Typically, a transmission pan drop & fluid change only changes about half the fluid.
What does transmission fluid look like on a car?
The appearance of transmission fluid can say a lot about its condition, but many contemporary vehicles don’t have transmission dipsticks, so checking the fluid requires opening a drain plug – that’s a job that is better left to a qualified technician. What Does Transmission Fluid Look Like?
What’s the difference between a transmission flush and a drain?
Gravity is simply not enough to remove it because it sits inside other internal parts. A transmission fluid flush, however, uses pressure to push all the old transmission fluid out of the system as it is refilled with new fluid. It is more of a fluid exchange than a drain and refill.
What happens when you change the transmission fluid?
In a transmission change (sometimes known as transmission service) the transmission fluid pan is drained and the filter is replaced. Transmission changes do NOT remove all of the transmission fluid from the car and often times up to half of the fluid can remain.
Which is better transmission flush or transmission change?
Once all of the old fluid has been removed, entirely new transmission fluid is added. In the situation where you have put the wrong transmission fluid into your car, a transmission flush is going to be a better option than a transmission change.
What happens if you add ATF to a CVT transmission?
In a CVT transmission, it is impossible to drain all of the CVT fluid. If you have accidentally added ATF, your transmission would then contain a mixture of ATF and CVT fluids.
What kind of transmission fluid do you use?
Continuously Variable Transmission Fluid (CVT) A continuously variable transmission is a type of automatic transmission vehicle. This type of transmission can change seamlessly through a continuous range of gears. It is able to do this by running on a series of pulleys connected with a steal band, rather than a fixed set of gears.

Why is it risky to change transmission fluid in high mileage cars?
Why is it risky to change transmission fluid in high-mileage cars? If the fluid has never been changed, it might be contaminated by products of wear. In a worn-out transmission, these products of wear can temporarily “seal” various pistons and O-rings. Once all the dirt is flushed out, the transmission may start slipping or shifting differently.
How often do you change transmission fluid and filter?
For example, the manual for the 2018 Ford F150 says “Change automatic transmission fluid and filter at 150K.”. Volkswagen recommends changing the fluid and filter in the DSG transmission (automated-manual) every 40,000 miles (for 2012 models).
