Did you check the level with the engine running
Ok, well we both know it cant just dissapear and if its not leaking externally, AND there is no tranny fluid in the coolant, then it has to have been not filled all the way. I mean its just impossible to dissapear...are you sure there is no tranny fluid in the radiator. It will be real obvious if you take the cap off the radiator???
You still there?
