Yes, I did a lot of searching, actually 2 hours worth and I can't seem to find the answer I'm looking for.
DIY: Full Flush for Automatic Transmission - Tacoma World Forums
I saw this thread on tacoma world using the transmission fluid line to the radiator to drain old fluid, I understand the concept, but in in the post, he said he started the engine and shifted through the gears even. Wouldn't that be bad for the transmission with 2-3 quarts draining each time? Running the transmission with a lack of fluid?
Also, If i was just to do the traditional drain, fill, drain, fill, drain, fill until happy method, after each time I fill it, should I take it for a drive to get all the fluid mixed in?
