Hello I just watched your video. I have left side drive and I just changed fluid and used red line synthetic. Should I change that out with different oil? Not sure if left side and right side drive makes any difference. Thanks for any information appreciate your advice guys
Red line is a very good oil for the older Baker and Jim's transmissions, but not for the newer RSD. Red line is to thick to lube the inner bearings properly. Drain it and use Lucas 75W140
