Looking for thoughts and opinions. 2015 ram 1500 with alittle over 100,000 on it now. Was looking into doing a transmission service when I discovered there is not a replaceable filter. I have done some research and found that Dorman makes a pan with a replaceable filter. With that said I’m leary of Dorman stuff due to the dubious quality of many of their products. Is this a good thing to do, or is there a better way to go. Getting ready to tow a trailer (5000 lbs) about 4k miles so I’d like to service it if I can.
