All other gears seem fine... R, N, 2, 3, have not pulled to OD since it locked out.

Well, it was normal this AM. I don't get it. This occurs once every month or so. Just seems random. I do remember it happening with the original transmission on a long cruise before, when i came to a long, slow stop off the interstate and it did not go to first for start off. It seems worse when I am at a slow roll and it just holds second as opposed to dropping to first. And once this happens you can completely stop and it still won't go to first.

Also, although the trans TCC tables are commanded not to lock the converter in third until 28 mph some days it will lock as low as 22 mph. Computer issues??
