[quote="CVPost-mgeez"](reply to post at 13:27:06 08/19/19) [/quote (1) the cooler is in the high pressure loop so it runs well over 100 lbs normal operation so I do not think that 120 lbs will damage it unless it is badly pitted or eroded,
(2) the control valve contains a pressure regulator that sets up system pressure and I have seen the spool valve get hung up on rough spots that develop in the bore, it is located below and centered between the two spools on the control valve. The valve will have to be removed to get a proper view of that.
(3) The pump has a cold oil relief screwed into it to dump oil in excessively cold temperatures. There was a design change on them back in the day where the old style ball and spring type was removed and a new design was installed.

(4) When the pedal is depressed the oil to the clutch is dumped to allow shifting, when this happens the pressure on the gauge will drop down to slightly below 1/4 of the gauge scale, 0 psi means something is not right, at that point you are reading converter charge pressure, at this point the converter charge pressure is applied behind the multi disc pressure piston to retract the pressure plate so minimal gear clash is experienced. Your air pressure is what is causing the clutch piston to retract. In my opinion the pressure regulation system in your TC circuit is at fault. The curved big pipe up out of the top plate is pump supply, take note to which pipe you are supplying pressure to that causes the pipe to sing, if applying pressure to the pump pipe causes that possibly the cold oil relief is the issue, normally they are set well above system pressure but if failed they could be all over the map. Get us as much info as you can, there are a couple of us on the forum that can help you out, OH by the way, get filter in it rite now, you are working with parts that are made of unobtanium. I just welded up a worn shaft for the TC PTO shaft feed and cut the sealing hook seal groove back into it.
