CVT Transmission Service

#1
Happy Weekend Everyone,

I have a 2017 Corolla LE with 30,000 miles, and I would like to keep it running well for as long as possible. My question is, should I service the transmission or not? I do not see any mention of tranny service in the maintenance guide, and I have read some conflicting opinions. It sounds like if I am going to do any maintenance I should start now, as doing it after putting on a lot of miles might actually do more harm than good.

Thanks for any input!

I have a 2014 corolla with 67000 miles and had mine changed at the dealer at 60,000 mile. Was it necessary? I drive pretty modestly , no hard take offs . Just try to do things that hopefully keep the car in fine condition.

Thanks for your reply. I want to keep mine running nice as well.

Yes : it mentions to check every 30K and change at 60K (for severe usage). It's the same indication for any auto/CVT trans from Toyota. 30K sound a bit overkill - more like for a manual transmission - but like early oil change, if it brings nothing, it also can't hurt !

Just curious... What are you guy's paying for the CVT service? I'm just now starting to check into estimates as I'm approaching 60K miles. Dealer quoted $300. Looking at independent Toyota shops now. Looks like the fluid alone is $$.

I would change the CVT transmission fluid every 30-40K, most especially on any random-reliability push-belt CVT. You can't baby those things enough & count yourself lucky if it makes it to 120K.

I also plan to change the fluid in my manual transmission every 30-40K. Areas of extreme hot/cold weather seasons make this doubly important, & it's the best way to maximize your chances of your transmission lasting as long as possible (plus not driving it like a hormonal idiot). :p

Actually, I sent an email request to Toyota customer service regarding the CVT fluid change interval since the dealers in my area are providing conflicting information. Some say 60K, most specify 100K earliest. My owners manual has no reference to CVT service at all.

The owner manual doesn't, but the maintenance guide that comes with the car (at least came with mine) also says to inspect fluid every 30K (and decide, I assume, except for severe service which recommend a change at 60K). It's the same whether AT or CVT.

I'll have to take a look at my guide. Inspect transmission fluid on a CVT. I wonder what that means. No dipstick. Probably just check the level with some type of an acoustic sensor. Well... screw it. Not paying for that, if no leaks. I'm going to wait until 100K for replacement.

As far as I know, it's about retrieving codes, especially about temperature peaks, a critical data to insure the fluid wasn't compromise at some point. And visual inspection for leaks. Not a big deal all in all.
