Called the dealer again and found out the fluid price total is aprox. $130 not 130/liter. Sorry about the miss information. Total job is about $358. Whats your opinion about an extended warranty? Side note: thanks for all the great information!

What type of transmission fluid did you use ?

It is sad. And I really don't blame the dealers. It's the manufacturer, Toyota. BMW is also guilty of this issue with trans service.

Yes, the procedure is very temperature dependent. I looked into doing the procedure as I DIY many things with my cars. I chose not to do this job and to pay someone to do it. To do a pan drop, you have to have the car level. The drain is the same as the "dip stick". There's a tube inside of the drain plug assembly. You twist out the tube when you drain out the oil in the trans. You reinstall it when you're ready to fill the trans back up with oil. The next step requires a scan tool as you have to monitor the temp of the trans. It has to be in a certain range which right now escapes me. If you don't fill the trans to the proper level in this temp window, you can either underfill or overfill the trans. The reason being the trans fluid expands in volume with heat. The tube inside of the drain plug is used as the measure for proper fluid level when the proper temp is reached. You fill the trans until you see trans fluid start to spill out of the drain tube when the proper temp is reached.

However doing it this way will not get the oil out of the torque converter. So you will have some old oil in the system if you just drop the pan.

I've seen others do it without worrying about doing it the official way I outlined above. They just drain the oil into a measuring container and then pour back the same amount when filling with new fluid.

I opted to do a flush as it gets all of the oil exchanged out of the trans.

What type of transmission fluid can you use beside the recommended one ?

I mentioned it in post #1, 3, and 14 that the shop I used has a BG flush machine and used BG fluids.

I have been reading this forum and posts made by zx10guy and RoLleRKoaSTer have been posting and honestly this has to be the best thread on here. I have a 2021 Toyota CHR with 14000 miles on it. I don't drive it too much but I am well aware of the transmission flush that you have mentioned above. If I don't drive it that much, would it be wise to wait to get a transmission flush when I get to 30k or before (maybe sometime in 2024) when it is the 3rd year that I have owned it (I m sure by that time Ill still have less than 24000 miles on it). I hope my question doesn't sound crazy but after reading many conversations of people with other vehicles with CVTs and how often they do a transmission flush I definitely want to do these every 30k miles to keep my CHR. Its sad that they stopped selling it in the US. Thanks in advance.

So drive more. Just kidding.

Doing basic math and making assumption about your future driving, it appears you're putting on 7k miles a year. That means you'll get to roughly 30k in another 3 years loosely. I'd probably wait till then to do the flush or maybe one year prior.

Something that I didn't realize was a thing was the shelf life of oil. This came up when I was doing an oil change to my 97 F150 pickup which I assumed ownership from my step father a few months ago. I had 6 quarts of Mobil 1 synthetic in my parts cabinet in my garage for years. Never opened. Figured the oil would be fine to use for the F150. When I poured the our out of it, the oil didn't even resemble motor oil anymore. It had a reddish tint to it resembling transmission oil. I did some research online and it appears Mobil 1 recommends using their synthetic oil before 5 years is up. This 5 year limit is assuming the bottle has never been opened, not exposed to UV light, and stored at proper temperatures. The 6 quarts of Mobil 1 met all those requirements except I've had the oil way longer than 5 years.

Oil life is shortened even when it's in an engine which is only periodically operated. This is due to exposure to air and all the byproducts that result from combustion. That's why vehicles which have low annual miles are recommended to have the oil changed at least once a year on a time basis rather than mileage basis. I've personally have gone longer on a time basis with my motorcycles. But never reaching close to 5 years. Since our transmissions don't have byproducts from combustion and only degrade mechanically due to heat or usage from shearing that occurs from lubrication, that leaves exposure to air that would be the biggest culprit for you.

So in summary, I'd run it out another 2 to 3 years before doing a flush. But that's just me.
