Hello all!
I've been noticing in mornings when starting the car and putting the shifter in Drive, it doesn't move when accelerating, it takes a couple of seconds to catch up, it doesn't happen when putting the shifter in Reverse. Once the car is warm enough it operates normally, ATF level looks normal , it happens when it's been sitting for hours and I decide to use it. Anything I should look into besides checking the ATF?

Not much can do. Check trans pan oil filter for plugging and change ALL the fluid.

This delayed shifting can be due to seal wear, worn or low fluid,
