As a auto enthusiast, I similar to take care of my ride. This includes periodically changing fluids like Engine oil, brake oil, radiator fluid, and transmission fluid. Just, I hear it all the time from mechanics to avert changing transmission oil if the car's working fine.

My answer to that is off-class the auto is working fine because I regularly change fluids. I hopped on the cyberspace forums to discuss this and got more people saying that I should not bother replacing transmission fluid. This doesn't make sense to me.

Then one day I came across this youtube video that explained it actually well:

So what does he recommends? I learned from this that it's crucial to modify the transmission fluid periodically. Merely, if your car is a loftier mileage vehicle (call back 94k miles or 150,000 km), and is still running on factory-filled transmission oil, you lot are ameliorate off only leaving it alone.

However, it'south best to change transmission oil at around every fifty,000 miles (80,000 km). If you regularly exercise this that you won't have to wonder if changing transmission oil next time will cause trouble.

Several vehicles nowadays come with lifetime transmission fluid that the company says doesn't need replacement. Only, that's non really your best choice if you lot exercise intend to keep the car for a long fourth dimension. Car manufacturers normally practice to comply with the environmental norms and to bear witness that their cars are depression maintenance.

That'due south because flushing the transmission increases the chance of some gunk getting stuck in the narrow oil channels. And it tin even harm the aging condom seals.
