I don't really know what damage is truly possible, but most drain and fill procedures that are provided usually ask for transmission fluid should be drained when warm and at running temperature. And fill level of new fluid checked when again at running temperature. The fluid leaving obviously will drain out much better when warm. The replacement fluid's volume changes as it warms up, it expands and raises the level somewhat. How much in all honesty I wouldn't think too much to do drastic harm but again, I'm no expert, just picked up on it watching the good old Youtube videos. I will admit, I own a 2012 Altima with 190,000 kms on it and have followed the manufacturers replacement schedule for transmission fluid and so far so good. I've also had a 2009 Murano that had a transmission failure and new replacement covered under extended warranty at 160,000 kms. It went on to rack up up 390,000 kms or 230,000 on the replacement transmission, with no problems. I had to scrap it due to rusted subframe under engine compartment - unsafe and too much to fix.

The NX Hybrid transmission is really not a true transmission design of yesteryear. No clutch packs, no torque converter, no spool valves. Nothing but some gears. See my post #10 video.

 

Agree with you 100%. I listen to the manufacturer of my vehicle. I have 100% faith when they tell me it does not need to be changed. I also have 100% faith in my Lexus local shop manager and friend that's been trained by Lexus for 25 years and worked on their vehicles for 25 years. He went to the factory that manufactures automatic transmission for training. He asked the question what's the number one cause of transmission failures and their response was the wrong fluid and the wrong amount of fluid. Both factors in changing their transmission fluid. I've never changed mine in six Lexus's and of course I've never had a problem with the transmission.

 

Did he ask if you service the transmission correctly, have they seen data to the effect of transmission failure or poorer outcomes compared to unserviced units?

 

True statement on the Hybrid eCVT.

 

How to say that you are not an engineer without saying it, haha But I envy that kind of faith

No one at factory will admit to someone from outside that tranmissions fail because of poor engineering or wrong maintenance procedures(which are result of ecology etc.) it's always the mechanic's fault

 

For those who would like to understand the issues of todays modern 6-8-10 speed transmissions, I'm talking the big guys here, Ford GM Stellantis, what they're struggling with, is quite frankly cost cutting on there designs and ultimately enabling early demise of their transmissions.
OF NOTE: This video discussion is not relevant to Toyota's eCVT designs at all, but rather does a good job of explaining how and why's of high occurances of valve body and electronic failures on typical rear / all wheel drivetrains

 

If I thought the manufacturer of my vehicles was lying to me and was hoping my transmission failed out of warranty I would sell both and never ever buy another. I find it interesting in your loyalty to a brand that is deceiving you and hoping you have to pay them $7,500 for a new transmission. Amazing loyalty. Most would be really pissed.

 

It's a lot more complicated than 'hoping my transmission failed out of warranty". Modern emmision standards take into account all waste produced by consumables. This is one of the main reasons why "long life" or "lifetime" fluids exist.
Every car manufacturer is currently struggling with being compliant to Euro 6 standard in Europe, for example european Nx350h lost 40 Hp this year due to emmisions.
So writing in manual "Change ATF fluid every 60k kilometers" would mean not getting homologation in many markets

 

Couple of questions here:
How in the heck did all that dirt get into those covers?
Wouldn't you have to be nuts to get under a car with those ramps?
Beating on it isn't the answer, right?
I could go on but why bother..........

 

Agreed Tinkertech, I don't claim this guy is all that smart. To begin yes a Tesla is friggen heavy! And not that cheap, or wasn't at first, why the heck is he choosing to drive down dirt roads with a car like that. I would've bought a cheaper less fragile car. Anyways he shows where the dirt is migrating in through the lack of coverage in the wheel wells. I was just wondering if any NX owners have seen dirt collecting up under our covers. If so I would make a habit of removing them and cleaning things up.

 

Do you know what is the first transmission oil change on Detroit DT12? 400,000 miles when hauling up to 80,000 lbs, with warranty up to 750,000 miles.
Now Toyota says 60k miles if you are hauling 2,000 lbs extra 😁. OK they know better and want to be safe.
And people push it down to 40k when hauling 1 gallon of milk from grocery store 🤔.
For eCVT in hybrid which doesn't see any load at all unlike regular AT. 🙄😐

 

Exactly what Toyota says and my Lexus dealership service manager a friend with 28 year of Lexus says to do. Never change

 

Go to a Lexus or Toyota Dealer Service department. Ask the Tech's that have worked there for years, and seen lots of Vehicles, in service and the Master Tech's if they change their Trans fluid on their own personal Lexus and Toyota they own?

 

I did asked the service manager who is also a friend and would trust his opinion more than yours 10x. Again if you think the manufacturer of your vehicle is lying to you and goal is to destroy your transmission would sell it today and never buy another.Lets see sixth Lexus over 700,000 total miles and never changed and guess what never had a problem. But you change the heck out of yours. Post your transmission experience.

A guy on YouTube had driven his Tundra hauling heavy construction equipment 1.5 million miles. When asked about his transmission said I never changed it and had to replace it at 750,000 miles. If mine last to 749,000 miles I am okay with that.

 

FWIW thats AI slop.
