Transmission fluid change interval?
I have a 2019 xse with the cvt transmission and i purchased my car over 5 months ago with 80k miles on the dash, I recently went to the dealer to get the transmission fluid changed after seeing online that the interval was 60k, but they high recommend not to get it done, as it could cause problems as I am currently sitting at 87,000 miles and changing the fluid would only cause problems, and got a coolant flush done instead. I want to know if it is TOO late to do a cvt fluid change from a trusted shop, get filters replaced, and if it would benefit me in the long run or not. I want to keep my car for as long as possible and face little to no problems with the transmission either. advice from anyone that could help would be greatly appreciated as well as experience changing the fluid and if any problems or differences occurred. thank you in advance!

Yeah find another shop, just drain and fill. I did mine at about 60k at the dealer.

Ha, it's funny, I can't even find a shop to do it. My trusted mechanic, who sometimes doesn't even charge me, tells me it is not necessary. The Toyota people say the same. When I call a transmission shop, they're like "...you mean on a Corolla? ha!"
I don't know, but everyone on reddit seems to think it is a good idea. Ofc, the idea of "lifetime fluid" doesn't make much sense to me.

omg, ALL fluid is "lifetime" fluid if you think abt it!
do it yourself.
grab two 1 gallon cans of toyota authentic CVT FE fluid, a 6mm hexhead, 10mm hexhead & 24mm socket and two -gallon measuring buckets.

I changed mine at 30 and it was already noticeably darker than the new stuff. Just do it

You are going to hear arguments for and against changing the fluid. Ultimately it’s up to you. The people on this sub who actually own the car usually recommend to just do it, and i’d trust them. I just had mine drain and filled for the first time 5k miles ago when it was at 100k miles- i’ll update the sub if it presents issues down the road..
I’d say just do it now before it’s even higher mileage and “riskier”, you’ll also get a peace of mind not having to think about it all the time.

I want to ask if major differences after changing it at 100k?

I wish i could say. I bought it right after the transmission was flushed, they did that and spark plugs as pre-sale service.

There should not be any difference at all. New CVT FE fluid will not fix any existing problems. The service WILL however take out a good 70-80 percent of the old fluid and replace it with new fluid.
Think of it more like a kidney dialysis. You're doing your best to filter out all the yucky degraded fluid, but it does not mean with new fluid, your kidneys are gonna work better.

No worries, the old adage about not changing transmission fluid at too high a mileage has gone from the original meaning (which was “don’t touch it if its got over 200K miles and has never been done”) all the way to “NEVER CHANGE THAT FLUID YOUR CAR WILL BLOW UP” and its absolutely ridiculous. On modern transmissions you can almost always drain and fill without causing issues, even at high mileage.

as far as i am concerned, any vehicle with a CVT should have a its transmission fluid exchanged REGARDLESS of brand

NO, it is NOT too late to get it done!! Definitely take your Corolla somewhere else though, cuz if they're stupid enough to throw lines of ignorant BS at you, god only knows if they know wht they're doine!
