In one of Scotty's recent videos he advised changing the transmission fluid in the Toyota Avalon even though it has lifetime fluid so the old fluid doesn't wear anything?But in a earlier video he said for an SUV to not change the transmission fluid for a similar reason because the Suv broke down. Which one is it? I got a 2017 Mazda 6 over 100k miles that jerks out of 2nd gear and while braking.Transmission fluid is usually one of the things mechanics advise in addition to repairing the issue.I can't replace the car so I don't want to risk a fluid change if it will make things worse.Spark plugs, ignition coils,and valve cover were recently replaced.The jerking issue was a problem before the replacement. The car does need pads/rotors but that is not causing the problem. Anyone familiar with Mazda knows its brake issues are distinct. I've had it long enough to tell the difference.

There is no such thing as "lifetime fluid".
On this site we have probably been asked about a quintillion times "Should I change my transmission fluid? There is no single answer. See the FAQ for details.
I know there is no such thing as a lifetime fluid.Also know there is a million answers to this question. Which is why I added details to my post.I'm trying to figure out what would be the best option.Leaving the fluid or changing it?
Edited-Because autocorrect
Only you can make the determination of the best option, taking into account the type of transmission, mileage, type of usage, maintenance history (if any), and an evaluation of the current condition of your fluid. All of this is covered in the site FAQ.
@chucktobias ... and service history
@imperator - I had just edited and added that right before seeing your comment!
Scotty in general does not advise changing it on high mileage american cars in if it has never been done before.
First, inspect the fluid to see if it's burned, dirty, at proper level, etc. If it's nice and clean and at proper level, then most likely your problem is not fluid. Secondly, if you have easy access to fluid through dipstick, you can try pumping a quart of old fluid out and putting quart of new fluid back in and drive it for a while just to see what happens. You can do that as many times as you want...
If you all ready have a problem what could it hurt...I would get an extractor and pump out all you can. Note how much you get out and replace that amount with OEM fluid.. I have changed it in a 2007 Honda Odyssey, 1997 Chevrolet pickup 1997 Toyota Tercel and a 2009 Toyota Camry didn't notice any difference in any of them...
Thanks everyone for the great tips and advice!
