It is about time for me to do this, and I was wondering which type of fluid yall recommend, and when i drain the torque coverter, how do you refill it. Do you just add transmission fluid then crank up the truck and let it pump the fluid in there? And I want to install a TansGo shift kit, so should ido this at the same time?

 

Here is how you do it:

Yes, the torque converter fills from the transmission pump.
