For the first two months of owning my Kia I scared the **** out of myself at one corner of my commute where I always roll in and don’t stop completely. Once I realized what was happening, I changed my behaviour and I haven’t felt anything untoward from the 7 speed tranny for about 2 years now.

Not cool that I have to do this, but getting on the gas too fast is guaranteed to snap into first gear abruptly and getting that lurch.

Again, here's a thought, especially with your "when cold" comment. Start out in ECO mode when you leave your house in the morning. I would bet money that you won't feel any jerkiness.

This is sad to hear. Especially after hearing about 2018 Camry and 8 speed transmission issues and the reason I joined. Put this together with out of control price structure (nickel and diming features that should be standard -- putting hubcaps on a near 30k car?) and the Honda CRV is still a better value after 2 years on the market, which is not something I'm happy about since the CRV has the winter oil dilution issues. Honestly, I can't for the life of me think of any reason a car should have an 8 speed auto transmission in this day and age, especially when modern CVTs are best product on the market today. It's not just toyota, every company putting high gear auto transmissions are having issues with them.

It can be hard to reproduce - you need to catch the transmission with it's pants down, so to speak. On my test drive w/ the Toyota specialist, I was able to sort of get it to happen, but not as bad as I've had it happen. The irony of it all is that in my tooling around after coming back from the dealership, I had it happen three times, a parking lot, right turn with a yield, and left turn from a turn lane. It's somewhat random for me and happens maybe 20% of the time, if that, depending on where I'm driving. My daily commute doesn't really cause it for the most part.

The Specialist didn't seem to be aware of the TSB for the Camry...

I did a few trips in ECO mode "just cause" and I found myself wondering if I was actually getting worse gas mileage! That aside, I didn't experience the jerky coast and go, but then I hadn't been in normal mode for that period of time.

Changing the modes to sport, eco, snow did not seem to prevent the hard shift when stopping, although, snow mode seems to make it happen less.

I'm fairly tame compared to most of what I see around me. It should learn my driving style and just work properly. Nobody else drives this vehicle. And "coast and go" scenarios come up all of the time for pretty much every driver...

I’m not saying your a bad or aggressive driver, I’m just saying that your driving style might be the reason you’re getting the jolts. Like I said further in the thread, I used to get it often in my Kia but haven’t felt it since I changed the way I drive.

Asking an inanimate object to adapt to your driving style is a bit rich, don’t you think?

All he has to do is visit the 8th gen Camry forum at TN, he's either ignorant or playing dumb!

It is definitely not something specific to the RAV4, and it’s not likely to be something they can fix.
Do you have any specific articles that point out this type of behavior in other makes?

I'm not sure why it cannot be fixed - seems like the programming needs to be tweaked. 2019 Adventure I drove didn't do it, nor did the 2019 Camry that I drove for around 120 miles, and that in situations that it could have easily happened in my Rav4. Of course the Camry is programmed differently than the Rav4, and I guess they have had a firmware update already anyway. And of course some people aren't noticing any problems. The coast, go and jerk if pretty obvious if you have it...

Our RAV4 does not do this, but our old POS Chrysler 200 did it all the time, and was very jerky. They did software updates after software updates and still never did fix it before we traded it in for the RAV. No such issues with the RAV4's transmission. Also, on the cars with those problems, it is the type of clutch they are using in the cars. Chrysler told us after the fact that it was a know issue and had no fixes,,,,,guess thats one of the reasons they no longer make that Gem of a car.
