I second this. CVTs are very sensitive to overfill/underfill of the fluid. Also after you fix the fluid issue if it ends up overheating again there are alot of aftermarket transmission coolers that work great with the Nissan cvts. I hear good things about the Hayden brand coolers.There are red aftermarket CVT fluids out there, so the fluid itself isn't necessarily wrong. I suspect it isn't, because even a few tablespoons of "regular" ATF will usually be fatal to the Valve Body. However, being overfilled by that much can destroy any CVT very quickly. You did the right thing getting the excess out of there immediately, but if that didn't help with the slippage, then the belt may already be cooked.
