The current Tacoma seems to never be in the correct gear, IMO. Like all modern automatics, it tries to upshift as quickly as possible which is an annoying (but common) trait, but it also has this weird downshift behavior that lurches the truck forward at low speeds, and it seems to always be confused about what gear to choose in stop-and-go traffic or merge situations. It's also just fairly jerky and the drivetrain feels like it came out of a tractor with regard to NVH.
The 2GR-FKS in the Camry, Avalon, RX 350, Highlander and ES 350 is a well sorted powertrain that is much more polished. I think that's also the same one your Sienna has, and I'm surprised that yours is frustrating. 295-301hp and 267lb-ft of torque is a better number for marketing purposes - vs 278. That motor feels three generations more sophisticated and refined vs. what the Tacoma got.
I also think a big part of what's frustrating about these modern automatics is overcoming the learned logic. For example, if your wife generally drives it and is a more passive driver, then you hop in and have a heavier foot, you're going to be frustrated because it's adjusted to her more relaxed driving habits and won't drop gears as quickly (or as many) when you stop on it, etc. In my experience, it takes ~2 weeks of daily driving for these automatics to adjust to new driver habits.
Nope, i am main driver of Sienna. Been thru 2 software updates...better. But not as responsive. At certain speeds (low), if you gas it, you get nothing............then it downshifts jerky. Sienna forums is full of complaints. My Sienna is 2017 BTW. I am used to it but still surprises me sometimes.
