Joe, sorry man, but your quest is futile. The only way to get ALL of the trans fluid out is to pump it... and the only way to do it at home is to put extra lines on the cooler, one going to a bucket, the other going to a fresh supply, then idle the engine until the stuff flowing into the bucket runs clean.

There is another way; keep changing the few quarts from the drain plug over and over until the stuff starts to look clean... this could take hundreds of quarts, though...

Seriously, Aamco, the transmission folks, will get this done in a hurry, and for not too much money. It's like trying to service A/C at home, you just can't get it done right.

Sorry.

Nate
