Only notice upon 1st shift from park to drive on cold start after it sits overnight. Obviously it's on a fast idle when shifted from park to drive which is contributing to this. It seems like the engine rpm goes up a little above fast idle speed when pulled out of park and shifted into drive. The colder it gets outside the more noticeable. Trans shifts great between gears no other issues. Have 248k on this lx. Anyone else notice this with theirs?
