During engine break-in on a test stand, would it hurt to have the transmission cooling lines blocked? There will be no load on the transmission. It's really just on so I can start the engine with the starter.
Thanks

Blocked- yes.

Tied together in a loop- no problem

should NOT pump fluid in park unless it has a mod done to it so it pumps in park

bu yes a rubber hose loop is the way to go

I would also have fluid in the tranz so it not low and run it in N so it is luricating the inside
