2004 Dodge Ram Cummins with 75,000 miles. Had my tire shop/autocare center drop pan, replace filter and top off trans fluid at about 55,000 miles. The fluid now looks dirty. It's reddish brown in color. Should I change filter and top off again or do a flush at home by pulling the return line and replacing the fluid as it gets pumped out? I've heard horror stories about flush machines, but if I do it at home using the return line, I see no difference because it's the transmissions pump doing the work.
Thanks for putting up with my posts.
