2001 Ram 1500 Start engine without transmission cooler lines connected to radiator??

Those clamp things aren't made/intended to hold pressure, trust me, I had a coupla sets.
They are fine to plug the lines while the rad is out (for repair)to stop drips/leaking on the floor.
Looping the lines with a hose and clamps will hold the pressure.
(Demolition Derby tested, lol)
