Hey Scotty, I just bought a CLEAN 2011 Dodge Challenger R/T 5.7 Hemi with 91,000 miles on it. As far as general maintenance and fluid changes goes, the car seems a bit neglected. I am in the process of getting it in tip-top running shape and was wondering if you'd recommend changing the automatic transmission fluid/filter by dropping the pan or doing a complete flush/filter? The car runs and shifts normally in my opinion, with maybe a tad bit of chunkiness when shifting gears. I'm a DIY guy with 7+ years experience of working on and maintaining cars so I pretty much know my way around cars or can figure it out, but have always owned manual transmission vehicles. In your experience, what do you recommend? Thank you very much for your time Scotty!
