Just wondering if anyone is running schaeffers all trans and what you think of it. I have been running their 5w40 9000 for almost 5 thousand miles and love it so far. Also use their winter fuel treatment. I used to run rottella 15w40 with lucus syn additive and my performance would always drop badly around 4k and would get hard to start around 4500. I'm a believer in their oil but haven't tried the atf. My tranny has 'morning sickness' and our rep said it would take care of it?? Thoughts?
