1986.5 Automatic Shifting High (and sometimes low?)

[M47R1X]

Yes, the speedometer still works. It was a hunch in the wrong direction. I'll take a look at those later today. Also, I was looking at this trying to find out which tests I had done previously, and I think I did all of the tests up to (and including) page AT-20. I'd been working on it all day and I finally had a "fix" with manual shifting and left it at that.
