Best c4 transmission oil

i read through almost every C4 thread on here and it seems like alot of people are going with Amsoil or Swepco.

someone also mentioned Castrol Dexron V.

I've always been a huge fam of Amsoil, so that's where my recomendation is.
As for how to purge your trans of fluid, the best way is to bring it somewhere where they have a transmission pump to exchange all the fluid.
