Anybody have information or tips on resetting the computers. Not sure if when my Toyota dealer does it, if it will delete the software updates or not. Bought a 2007 ES350 with 104k miles and not sure if these flashes/resets are something that needs to be done, now that the vehicle is being driven by a new driver. Aren't the computers like a learning thing and adjusts to the drivers? Tips/info would be greatly appreciated. Also doing the trans flush because the fluid is starting to contain moisture.
