I was researching this topic for my 2013 Ram, and found an aftermarket aluminum pan made by a company called “PPE.” It’s supposed to be the best, and it better be, considering it costs around $440. It has replacement filters and a drain plug. I have seen negative remarks about the Autotecnica and Dorman replacements. I’m also curious about experiences using the Ravenol fluid vs. the ZF Lifeguard fluid.
