SO here we go: The "blow" method: After disconnecting the drain plug: With both pipes disconnected and the lower pipe replaced with a "waste-pipe) leading into the waste-pan I blew with the air-compressor-gun full power into the upper opening on the radiator and out came the ATF, which was stuck in the radiator by the waste hose. Then I carefully blew into the 2 pipes going to the transmission and out came the old ATF by the drain plug opening and by those 2 pipes (2 pans required!)
