I used Mean Max's trick/ technique. Remove the shifter boot or whole tin trans cover with the boot and all if you have no carpet, remove the shifter from the trans with the 1/4 push down and twist. Then aftre you drain the old fluid replace the drain plug, remove the fill plug and then pour the 10w-30 right in thru the shifter hole. Stop when it starts to run out of the fill plug. I bought a 5 qt jug of Walmart super tech stuff. It takes just over 3qt's IIRC..
