Look, folks, this is an automatic transmission. It has 8 gears, and they are "more closely spaced" than the gears you may have had in previous transmissions with fewer gears. The shifting of this transmission is controlled electronically -- the car's electronics must choose one gear out of all of those gears, at any given time and situation. Unfortunately (for some people), the electronics must choose a gear, and the driver has to react accordingly, in order to drive the car smoothly. Note that CVT transmissions, for instance, "don't have any gears," so they lack this "problem" of having to choose a physical gear for each and every situation.
Is there anything "wrong" with this transmission? Most certainly not. The transmission with 8 gears was presumably chosen to compete with CVT transmissions, which can fine-tune the transmission with precision for any given situation, whereas an automatic transmission needs to be in one physical gear for any given situation. More gears, closely spaced, can give an automatic transmission "more precision" in order, presumably, to get better gas mileage than transmissions with fewer gears could achieve. And that's what is physically going on here. Add into the mixture the fact that the car has three different "modes" a driver can choose from at any given time -- ECO, Normal, and Sport. These "modes" are electronic programs that change things like the transmission shifting pattern, the accelerator pedal travel, and the steering control.
So, what is this "jerking" people have talked about? Essentially, you have the transmission either shifting up or shifting down. That's all there is to be seen here, folks -- the transmission is either shifting up, or shifting down. Again, that's what the transmission is supposed to do, and the transmission is working normally. I expect that this "jerking" is simply the transmission "shifting down" in given situations. The driver might have to do a bit of work in order to handle these situations smoothly, but I'll certainly be one to say that the Normal mode doesn't give you a lot of accelerator pedal travel in order to indeed handle these situations smoothly. I will say for the dozenth time, or whatever it has been by now, that I have most definitely found that using the ECO mode during in-town driving gives you substantially more accelerator pedal travel, and after trying all of the three modes at length, I have come to use ECO mode for almost all of my in-town driving.
So, again, "is there anything wrong with the transmission?" Of course not. Could Toyota come up with a different "program" for the transmission, which might help drivers "handle slow-speed situations smoothly?" Well, I suppose they could, but I would submit that TOYOTA HAS ALREADY GIVEN US a different program -- it's called "ECO mode." I have suggested that people might give it a try, but it's as if I'm asking them to go out onto some lawn, find a fresh pile of dog manure, and take a bite. I guess some folks would rather whine about it. But, consider this: If Toyota did "give us a new program," would it be any different than, say, "making Normal mode more like ECO mode?" My bet is that this would be pretty much what Toyota might do, but I'd bet more that Toyota probably won't make any such changes. Again, "if you want Toyota to give us a different shifting program," I would answer, "Why not use one of the three programs Toyota has already given you?"
So, yes, I have experienced what I think people are talking about, but I have learned how to drive my RAV4, and how to use ECO mode to drive entirely smoothly while the transmission is navigating these closely-spaced gears. I don't consider this to be a problem at all, but it does take a bit of work in order to drive smoothly in these situations. But, like anything else, once you've learned what to do, you instinctively just drive smoothly, and it's just not an issue anymore.
In the end, I think we can always look at the current-generation Camry, and see if Toyota does anything regarding the transmission shifting program for that vehicle. Bearing in mind that only the very highest models -- the XLE and the XSE -- have anything like the three modes that every RAV4 with this transmission has -- ECO, Normal, and Sport. Given how most cars are generally not the highest-spec models, I think it's safe to say that most Camry drivers have no alternatives to choose from, like the ones all of us RAV4 owners do. But, again, keep an eye out to see if Toyota makes any changes for the Camry. If not, then don't expect to see any changes for the RAV4. And, finally, if you don't like the fact that cars are getting more and more gears in their automatic transmissions, you may want to go for models with CVT transmissions, instead, which utterly have no gears. As far as I can see, this is the whole story to be seen here.
