99.5 Pathfinder Downshift Issues

[OE812]

This is the first time I've had a driveability issue with my Pathfinder. Mileage is 78,000 and I changed the transmission fluid and filter about 10,000 miles ago. The pan at that time was clean with no metal fragments. Used 8-9 quarts of Nissan D transmission fluid. Anyway, I am getting 2 transmission issues and need to know where to start.

The first issue is when I shift from reverse to drive, there is a 2 second pause before it engages in drive so I can accelerate. It doesn't matter if the operating temp is cold or hot.

The second issue is as I am coasting >50mph and slow to 30-35mph and try to accelerate, the transmission doesn't downshift to 3rd or 2nd. But when I floor it, it abuptly downshifts to 1st and nearly red-lines until I back off of it.

Fluid looks and smells new. The level is fine.

Where do I start?

Any help would be appreciated.

Ran self diagnostic test...all ok with transmission apparently. 10 quick and consistent o/d blinks.

What next/?????
