Thanks for the top of making the test plate out of plexiglass Phil! I got a piece of 1/4" laying around that is large enough for the job.

The filter looked good as I had just replaced it less than 500 miles ago when I dropped the pan to change it and the oil.

To recap, I started getting the FAILSAFE message last fall when it started getting cold outside, which was about 2 months after I changed the fluid. If I shut down and started back up again after everything was warmed up (driving about 15 minutes), the message would not come up and the transmission behaved perfectly.

After about 300 miles of only having 5th and reverse, I checked the oil level, and it was exactly 1 quart low, so I topped it off. Unfortunately, that did nothing to make the FAILSAFE message go away. After another 200 miles, the restart when warm trick no longer worked.

The only thing I noticed out of the ordinary when the transmission was working, was that I did get a little push on the 2-1 downshift, but only noticeable when I specifically felt for it.

Been tied up with other projects around the house since my last post, but will hopefully get back on it this week.
