Has anyone done their own tranny flush? I'm just curious to know what you thought about doing it if you have, and how much of a PITA it was. From what I can gather you would need to have the bottom trans line in the new fluid (a lot of it, 5-6 gallons maybe?) and the top line routed to a catch container. After you did that, would you just start the truck and cycle it through drive and reverse a few times, making sure to not let your new fluid container go dry? If I'm way off someone please let me know. Thanks.
