What brand of fluids?

[ShadowsFall]

right!
next we need the royal purple people and mobil 1 besides the op. then we can get the different mileage people. few others then we can start to see some fun.

I guess I’ll get the Purple People started. I run it across the board.

So if I want to switch to Amsoil transmission fluid, how do I get all the fluid out so I can fill it up with just Amsoil and not mix the fluids? I have watched videos on how people remove the cooler lines and start the truck and drain out all the fluid, I am not sure about doing that without running it dry.

You can do what's called a transmission flush, but I'v heard conflicting reports when it comes to that. I'v seen threads on here where after the transmission was flushed something went wrong.

I don't think Mixing the Transmission fluid will hurt anything. I changed mine back in January and I simply dropped the pan, cleaned it and then put it back on, then added Amsoil. I checked it last week and it still looks brand new.
