So I bought two np205's from JeffHK5 this weekend. drained out fluids last night to start the SYE kit install to the one I am going to use and found two different fluids in them. In the sm465 - 10 spline 205 there was a light gear oil. In the th350 - 27 spline 205 there was RED TRANNY FLUID?? I am confused. Should I refill the 205 I am using (27 spline th350 ) with tranny fluid? It seems that fluid would pass through the front seal into the transmission (since fluid can leak out of there). Any thoughts? PS - I have all the tech info offered from a different thread, to no avail with this question.
