I read in one of the popular diesel mags that it is ok to run auto tranny fluid mixed in with the diesel in our trucks and that it is great for lubrication and stuff. Is this true? Anyone try it and what were the results?

 

my father uses it in his 92 every other tank full big rig mech. told him to do it i think it is dexIII
