Default 6l80e cooler line pressure

From trans right to an aftermarket cooler? Still use the radiator as well?

Perhaps I'm reading this all wrong, but how the heck can the cooling line pressure affect the thrust on the crank? I'm not aware that any model automatic transmission puts significant thrust on the crank. I understand that with a manual transmission a depressed clutch puts significant thrust on the the crankshaft.

If the crankshaft's thrust bearing was toasted, I would suspect an improperly installed or built converter.

When the cooler is restricted it causes the pressure to push the converter forward

About 40 to 50 psi idle goes up then back down when reving
