Trans flush with no convertor plug...

Whats procedure? I'm thinking pull cooler line into bucket and run another line back to trans and gravity feed it new fluid in via funnel at about the same rate? In neutral so it pumps? Flush until it runs red or out of fresh ATF? Cycle the selector a few times to clear the passages? Dumb they didn't put a plug on this convertor. Fluid came out looking like oil but didn't smell burned at all. Weird. 194k miles FWD Transaxle. Thanks!
There are two ways of flushing/changing all the oil in your transmission.
A: I don't know where you live, but where I live, all quickie lube shops have a piece of equipment that allows them to change/flush your transmission of ALL oil in the unit. There is nothing really magical about this despite they often will tell you that the machine is doing all the work to get rid of your dirty oil. Some of these wizards will also inform you that their machine will, are you ready for this, BACK flush your transmission. The machine is smoke and mirrors game. For the machines I've seen, both in operation and at trade shows, the engine must be running. The reason of course is, without the engine running, the transmission pump aint working, and neither is the flushing machine.
B: Get two 5 gallon plastic drums and about 10 feet of transmission cooler line hose. Connect the hose to the transmission lines. Place each line in one of the buckets. Now here is the big secret :lol: :lol: :lol: :lol: , the discharge line goes into the empty bucket(bucket b), and the suction line goes into the bucket(bucket a) you filled with new transmission fluid. Put the car in neutral and start your engine. When you see nice new oil going into bucket b, you've flushed/changed all the oil in your transmission. When finished, shut the engine off and replace the cooler lines back on the transmission. Now, you can if so desired, let people know that you too can now FLUSH their transmissions.
Side note: If your converter is a lockup unit, you may have to cycle it a couple of times. Very few OEM converters have drain plugs in them.
Hope this helps.
