Slight Rumble When Cold
 

2011 Quest SL, 190K noticing a slight mechanical rumble like something is not engaging as you begin to accelerate from stop. Seems to happen mostly when cold, but goes away the more it warms up. It's as if there is a rough spot in something or a slipping. Trans fluid has been changed every 75K but concerned it's something with the CVT.

Thanks for your input.
