No, follow The Car Care Nut and your Toyota will last 500k+ miles.
Toyota Transmission Class Action Lawsuit
- Thread starter AJB0009
- Start date
The suggestion that the transmission is undersized for heavier vehicles reminds me of GM's debacle decades ago where they were installing the TH200 (appropriate for the Chevette) in larger cars (the Malibu, and perhaps the Impala and Caprice also).
The TH200s failed quickly.
Assuming this is the same transmission in my 2019 RX 350...or at least similar. I HATE this transmission in every way. Too many upshifts, too many downshifts, there is a shutter when in drive and stopped, and it can be clunky at times. Brought the car in several times when it was new for these issues and eventually they reprogrammed it and that helped a little but not much. It's a sever year old car now but only has 70k miles on it and while there is no signs of it failing yet, this lawsuit is the icing on top for me.
None of his advice will prevent this imo..

“One area of concern is the counter drive gear sub-assembly support bearing area (Figure 4). The nut that retains the races may come loose and allow the transfer gear to move. The condition is caused by a locking tab that keeps the nut from backing off its set position, which was not bent enough during assembly. Symptoms associated with this issue include the following:
- Bumps and clunks while transitioning on and off the accelerator.
- Whining noises inside the transmission
- Harsh shifting
- Reduced power mode”

If this was a GM we’d be on page 29 with most never having one
I’m doing every 30 with WS
Straight from the Tech’s mouth. Keep us informed. Thanks!!

2018 RX 350. Bought L/Certified in 2020. Got use to the quirky shifting, more or less, but for a definite flare at 3-4 shift when first driven. Dealer drove it and said "no problem found. Started holding the transmission in 3rd until about two stop signs from home plus another 0.1 miles and manually shifting up. Only by this was I able to prevent the flare. I asked the dealer to change the fluid at 60K and they flat out refused (too chancy, etc.). SO, at 70k, not having a way to level the vehicle with it high enough to crawl under, I had an independent shop who specializes in Toyota/Lexus (ex dealer employees) change it at 70k. SHAZAM! The flare was gone! I'll be doing that again at some interval I've not yet decided on. "No such thing as lifetime....."
It is a major pain trying to level our cars. Many are so low.
Great article. If one doesn’t encounter the servere symptoms as listed. Changing the fluid often and drive in POWER mode may give you a better driving experience as identified in the article.
I just love when we think a so called professional writes some article or talks about a topic, and still can't get it correct!
I guess you gotta be an old person to know better. As I see no roller bearings in that photo. Them's good old ball bearings.
Or is the issue, that they have to re invent the nomenclature to match the mind set?
Gee maybe there won't be anymore ball screws they can call them angular roller bearing screws.
No issues...yet.
The original TSB (T-SB-0008-21) is what I'm familiar with: https://static.nhtsa.gov/odi/tsbs/2021/MC-10188917-9999.pdf
I don't know if there are revisions to this, or separate ones that "address" a different issue.
There are complaints with 4th Gen Highlander an Toyota Nation, mostly with how Toyota is handling the issue. It appears that it's mostly a lack of replacement units.

I have only watched a few of his videos, but this is my "take". He appears to be very knowledgeable in the subject of "Yotas", and when a person becomes that familiar in a certain subject, it can be difficult to not come across as condescending to others. Yes, a great many people choose to be condescending because they want to "Show Off", but a great number of people choose not to do this and I see him, truly, as the latter. Unfortunately, someone highly knowledgeable in a subject, has to stay constantly aware of how they "come across" to others that may not have the same depth of knowledge, and as we are only human, we can have a "oops" incident. I hope that I was able to put my thoughts into written words with a modicum of ability. Heh, I used a complicated word.... Modicum. I is so proud of meself.
He strikes me as arrogant
A lot of "better listen to me or your Toyota won't last 100k miles" and "I know better than Toyota themselves".Engineering Explained or The Motor Oil Geek doesn’t give off the smug, condescending vibe that CCN gives me.I have only watched a few of his videos, but this is my "take".
