Resolved the issue. Started the morning by backing the truck into the garage.
Truck was reluctant to back up the drive. Had to drive up the neighbors drive and floor it to get up the drive. I knew I was going to find something..

Pulled the trans, rebuilt it, and reinstalled it today. The 3-2 down shift valve in the valve body was assembled wrong. The direct clutch pack was toast. Thirteen hours later, truck shifted into 3rd as expected.

On the test drive, something was going clunk. Found the left upper a-arm was loose. All the shims were laying on top of the spring bucket. Time for an alignment.
