The transmission pressure gauge also loses pressure same as torque converter when it gets hot.
    I had a transmission to would quit pulling after 30 to 45 minutes when it got hot. Turned out one of the cooling lines coming from the transmission to the radiator was clogged and not letting the cooled trany fluid return to transmission. Ran perfect after I blew the line out then I ran it 5 or 6 hours straight none stop pulling and pushing.

    Hole in cylinder wall from cavitation, sleeve seal leaking, cracked block, best thing I have found is pull oil pan and pressurize the coolant.
