Pressures could be high, but I thought reverse pressures were supposed to be 230-280. Now, I have not gotten around to measuring mainline pressures, but a fair number of people run 180-210 psi (in the diesel world anyway). A few have issues over 200 psi, but none have reported reverse issues. Still a possibility though.

No pressures in reverse in any gear but reverse/man low. Would a cross leak still be possible?

The TCC as well as the OD has been acting normally for a few days. When it would act up, it would ALWAYS unlock in 2nd. It only stalled a few times I forgot to downshift from 3rd (which was OD & Locked).

No issues with 3rd gear applying quickly as it's a Full Manual, trans can't shift by itself. Never any harsh shifts or slippage (other than reverse a day or so ago). Trans temps (measured in pan) have always been 120-140 while the weather was in the 80's.
