4L60E No 2nd and 4th
Ok installed the transgo replacement plate (which didn't come with gaskets so I reused the old/like new ones).
I now have 2th and 4th!
The vehicle runs excellent except for one concern:
If accelerating moderately to excessively, it slips from 2nd to 3rd for less than a second. And by slips, I mean the engine revs up about 500-1k RPM then settles into 3rd.
On slow acceleration, it shifts flawlessly.

If no change... Line-Pressure readings should be taken during the Shift-Flair.
If Pressures are dropping too low, then 3-4 Clutch Circuit leaks need to be addressed.
If Pressures are good...
Then the Third-Feed, Third-Exhaust, and Third-Accumulator Orificing needs to be reexamined.
