I got amsoil in my tranny. Ever since i put it in the shifts hold out longer and now at my 30k maintainance, its turning colors and smells as original stuff didnt do that. I dont know if my truck is taking a beating now with miles or its the fluid change. Im prolly going back to stock after my next 30k miles i put on it. Im not impressed with amsoil ATF 1 bit.

Mine did the same thing, but in a lot less than 30k. It turned dark purple / brown I dont know.

I'm a fan of Amsoil, but I am afraid to put it back in my tranny. The regular stuff is doing fine.
