my trans is going out on me (4T80E pump whining causing some slippage) and the fluid is pretty nasty. i put some lucas stop slip in it and it made worlds of difference so i think i would like to COMPLETELY drain and refill the trans with new fluid so i can make this thing last as long as possible. (wont be able to replace it until sometime in july.) i know flushes are bad, so im not going that route, and i know some people have disconnected trans lines and poured in new fluid while the old pumps out. my question is, what would be the easiest way to get ALL of the fluid out of my trans and not just the 6 quarts that come out with a pan drop? if its the disconnecting line method, where would be the easiest (and safest) way to acomplish this? my car is a 1997 eldorado ETC.
thanks for any and all help,
