Just about every person that has a 46RE has had this code and it is so annoying because you can spend all the time replacing solenoids, checking wiring harnesses, doing just about anything logical to fix the problem yet it always turns out to be something wouldn't expect. You want to know something, I'm wondering if the torque converter clutch is hung up or something, that would cause an overheating issue... Without being there it is difficult for me or anyone to with certainty come up with a solution, mainly because there can be multiple sources to the problem. First thing to figure out is why the hell is the transmission getting hot, is it cooling, is it the bands (maybe the rear band is too tight which does cause the transmission to get very hot), is it a hung up clutch... And so on, most likely once you fix the overheating issue, everything else will go away.
So find out why it's overheating, check the cooling system, make sure there aren't any clogs and the pump is able to deliver the proper volume in timely fashion. The worst thing that is coming to my mind is the lube feed hole in the intermediate shaft isn't aligned with the lube feed hole in the OD piston retainer. It doesn't have to be perfectly aligned but the closer the better and when you grenade a OD unit it is very easy to misalign the holes during a rebuild.
