Is anyone familiar with this issue: Upon slowing down from highway speeds (pulling on to off-ramp for example) the trans. ('06 5AT) seems to not wanna let go of the higher gear and feels as though it's binding before finally downshifting into lower gear. The cabin seems to become "boomy" ( a bass-y rumble ) for a few seconds before it shifts. Not sure whether it's 5-4 shift or 4-3.

 

Mine does this from time to time.Almost feels like down shifting too low a gear.Its like Im still going to fast for the lower gear it selected?
