Hello everyone, long time no visit! I have a 1994 Dodge Spirit with the three speed auto transmission, and I have a question about transmission fluid. I know the recommendation is ATF+3/4, but I don't know if that's what the previous owner used. There is a slight fluid leak, and I want to know if it's safe to potentially mix different kinds of fluid. I've heard that the three speed can use dexron/mercon fluid, and I have no way of knowing what's in it. There are no shifting issues that I can detect, so I don't believe the leak is too bad, but I want to be sure this guy hits 200k miles or more. Does anyone know from experience if it's safe to top off with new ATF+4? Or do I need to get it flushed entirely and start over? Thanks in advance!
