Thank you for being there for all of us neophytes! I just bought an old American Eagle with a MD3060 mated to a cummins 8.3. It seems to shift fine but the tranny fluid looks like it needs changing. It doesn't have the spin-on filter like the new ones. It just has two round covers held on by bolts to the bottom of the pan. I assume that's where the filters are. There doesn't appear to be any drain plug. Would changing the fluid and filters be a job that I could perform? I do so on my suburban 700R4 tranny. Are there any pitfalls / tricks I need to be aware of? Thanks again for your help. Regards, Rick from Paso New owner of a 1992 American Eagle with lots of problems!
