Do you have the ECT button pushed?

That doesn't sound right! Check to see if you have power mode selected or are you shifting manually?

Of course you can feel it shift, but it's not extreme.

Yeah - if you have the ECT/PWR on, it's like the car is always trying to stay a step ahead of you and will up/downshift to maintain an edge, especially on hilly roads. Just my experience.....

I had the same issue with my IS350, ask the dealer to do a transmission fluid replacement(flush is not possible) even if its too early. after a couple hundred km of driving with new fluid i noticed a difference and now its completely normal once again. its worth the try and also it shows the dealer your level of concern and maybe they will look into it farther after replacement of fluid, thats if problem still exists.
good luck!

It's physically impossible for him to have replaced any significant amount of your transmission fluid.

The best he could have done is charge you to drain about 10-20% of the fluid out and replace it.

Which wouldn't have fixed anything wrong with the transmission.

(and on US cars anyway the owners manual explicitly states the transmission is a sealed system and you never replace the fluid at all... I know canadian cars say something different but nobody has yet to provide any evidence that the dealers in canada are doing anything other than that minor 10-20% fluid replacement and then claiming it's a "fluid change")


More likely the computer had learned some behavior you didn't like and they pulled the ECU fuse to reset it while doing that minor fluid exchange.

Sure hope you didn't pay for the "transmission fluid change"
