How long can a transmission last without changing fluid?

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.

Can changing your transmission fluid hurt your transmission?

Transmission fluid is important for lubricating the parts of your transmission and reducing wear and tear caused by friction and heat. While changing your transmission fluid won’t damage the condition of your transmission, if you haven’t been changing it frequently enough, you may discover that your transmission slips.

Will I notice a difference after changing transmission fluid?

Transmission Flush All the old, dirty fluid is removed and replaced with fresh, high-quality fluid. You’ll also notice smoother, more consistent shifting since the new fluid will provide more effective frictional properties.

Can you change transmission fluid after 200000 miles?

Yes you can, but it might make more sense to scrap the car than try to resurrect it. If it has never had an ATF change, odds are that the new fluid will lubricate well enough to never let the transmission work.

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.

Should I change the transmission fluid in my car?

There’s a lot of urban legend around changing the transmission fluid in your vehicle. The biggest legend is if the fluid hasn’t been changed in a long time, it shouldn’t be because it’s old. That’s not really true, but here’s what IS true.

What happens to transmission fluid as it ages?

As the fluid ages, it’s likely to deteriorate and lose its lubricating and cooling capabilities. In addition, it can collect tiny metal shavings from moving parts and gunk that has built up inside the transmission; those could affect shift quality.

What does Flushing your transmission mean?

Flushing your transmission, on the other hand, allows you to completely change all of the fluid in the transmission. To flush your transmission, you attach a transmission hose to the input of the line that runs through the transmission and another hose to the output.

How can I tell if my transmission fluid is bad?

Wipe the dipstick with a clean rag or paper towel. Then look at the color of the transmission fluid. • If it’s bright pink -the fluid is new. No need to change it. • If it’s light brown with a hint of pink-It needs to be replaced. • If it hasn’t been changed in a long time-it will be very dark brown. And, it may have metal particles floating about.
