I have 30k on my 2016 LE, and I'm quite worried about having a CVT transmission. Hoping some community members have gotten lots of miles on theirs trouble free. I love the car and how it drives, just got worried reading crap about CVT's

just got worried reading crap about CVT's
Some people don't like the way a CVT operates and there have been some notoriously bad engineered units (Jatco Nissan...) hence the crap you read. Despite the impression, it doesn't mean it applies to all and every CVT, just like recalls and firmware updates on regular automatics from various brands don't mean the AT is a flawed concept. There have been a service campaign (firmware update) for Corolla which you should get if not already done. Aside that, those CVT have been in Corolla for now 6 years in NA (9 years worldwide) without a particular surge in complaints (TrueDelta, JD Powers, Consumer Reports) other than the inevitable odd unit of any human made thing. Toyota's maintenance guide is the same whether AT or CVT : inspect fluid every 30K (mainly check for codes and temperature peaks - the main cause of fluid degrading and the main problem with those first Jatco Nissan) and act accordingly, with suggested fluid replacement at 60K for "severe" usage. That's about where I'm at now. It's perfectly doable by yourself but I'd rather go to a trusted mechanic as CVT are simple in concept but require very precise variables.

The procedure is in the following link: https://www.pakwheels.com/forums/t/correct-procedure-oem-to-change-cvt-fluid-oil-in-altis-grande-1800-cc-2zrfe-transmission-k313/995963

I suppose you can use a OBD reader to monitor the transmission temperature but I have not personally confirmed it reads identically as doing it following this guide.

Temperature in Farenheit is between 104F-113F.

I personally recommend doing two drain and fill's to remove most of the previous fluid.


If you learn visually and there is nothing wrong with that here is a nice video to watch of the process:

@Di3S3L may be upwards of 300k.

CVT's have been in vehicle's since the 80's but not wide spread as we are seeing now. I also saw some buses are switching to CVT's to increase fuel efficiency

Most of these are CVT’s.

I posted one there from reddit showing a 500k+ mile 2016 Corolla with original CVT.

Does anyone know how much the dealerships charge for a fluid change? It seems like to much for me to do myself

Just check with the dealers in your area.

I'm at 152k on a 2015 S. I never had the CVT fluid changed, but I do 90% highway. I do climb a 9% grade daily - no problems so far with my CVT. The dealer I bought it from new wants to check it, but hasn't said anything about changing fluid. I went 200k with my V6 Solara before I changed the fluid, but that was a conventional torque converter trans. I'm more concerned about the LED headlights crapping out.

Sounds like you are waiting for a problem. I would service your CVT ASAP. Don't tempt fate. I've changed the CVT fluid on my wife's 2010 Prius twice and am doing it again soon and she has just a little over 100k miles now.

I know of cab drivers in NY who have almost 500k on their Prii? and have never changed their CVT fluid - and they deal with heavy stop and go traffic. I appreciate your advice, but I'm mostly highway and I don't do the stoplight Grand Prix with my Corolla (I have another car for more spirited driving). I changed my rotors and pads at 100k and there was no scoring on the rotors and a decent amount of material left on the pads (front and rear). I fell victim to my paranoia on that one. I understand that my situation is a bit unique, but it also shows the range that these CVT's are capable of working within, given the right conditions. I'll post an update when I reach 200k (just about a year from now).

Diff cvts there. I changed mine already and I’m at 40k
