I want to drain my transmission fluid (99 f150) and also found out there is about a gallon more in the torque converter.
What kind of tool or wrench do I need to pull the plug and drain that too.
Thank's Joe

 

18mm ratchet to turn the crank and a 7/16 socket to remove the plug.

put the transmission in Neutral. get a big flat blade screw driver and pry the converter over till u get to the drain plug. unplug the injectors. and crank the motor till the drain plug is at the bottom.

 

But with the TQ empty how is it going to pump it's self back up?

 

Put 5 quarts in the transmission. Start the engine and immediately add the other 7.
