Gear disengage or keep on D

Automatics, including CVTs, are intended to be driven stop and go, so there is no reason to shift to neutral when stopping. Vibration when stopped is normal with the Yaris, as the ECM really drops the RPMs when you are stopped to conserve fuel.

My re this was really thinking about 'pressure building up' with one's foot on the brake. I remembered this feeling from years ago, and had the same feeling (to a lesser extent) in the 3rd Gen rental. I didn't hear/feel the RPMs drop in the rental (couldn't see, no tach). Perhaps in both cases (the 3rd Gen rental and memories from the past) the idle was too high?....although I'd hope they'd keep their in house rental on a maintenance schedule that would prevent this.

Thank you CTScott for your reply...that really helped ease things out.

Jcboy will check the intake manifold and engine rubber mountings too.

Thanks

According to my scangauge in my auto RPMs do drop when stopped in D however the gallons per hour goes up vs. In N the RPMs do go up but GPH will drop .03 GPH to .1 GPH.

Thanks for the info!!!

I think I was off a little bit. .1 GPH was too high, most I've seen is closer to .08. I don't know if this is bad for the transmission bit I only do it when ill be stopped over 30 sec. To date no issues.
