I have searched for this w/no luck.
I am not sure what words I should use to describe this, so please be patient.
This is my first vehicle w/ an automatic transmission.
When my X has been sitting for a few hours and I shift from Park to Drive or Reverse to leave a parking spot the transmission does something odd.
It seems to shift hard (or not want to) shift into gear.
When the truck is parked for a short time I do not experience this quirk.
Someone had mentioned it is a result of fluids draining from point A to point B.

Ideas, anyone?
TIA
