As per Caman 96's post - just shut it down as soon as the flow becomes irregular.You're saying a person DOES NOT have to worry about pumping out all the ATF with the truck idling?
Well I tried to flush/change oil on my power steering without the pump running dry - there is no way currently known to mankind to refill the reservoir fast enough!I would have thought it would be like power steering where you don't want the pump to run dry.
Thing is though, it's not actually running dry - it's merely unable to access enough fluid to maintain pumping and pressure. For that brief moment, the pump is still wet with oil and thus lubricated.
