Trans flush
I had my trans fluid and filters changed before going on our summers Alaska vacation. The dealer initially didn't recommend replacing the filters, just flushing the trans??? When asked why, said they had issues with the pan leaking after removal. That I had a couple of weeks before leaving in which to observe for any leakage, elected to have them change the filters. I also had them bag the filters so I could examine what over 25k of towing our 13.5k toy hauler did to clutches, etc. When finished, there were no leaks and after examining the filters, was not able to find any significant residue. That was good. After the 16k Alaska trip and towing probably 14k to Prudhoe Bay and Inuvik, had absolutely no problems and even now, the color and smell are nearly the same as prior to the trip. No doubt will have them changed or do it now myself after next summers trips which will be shorter. Would definitely recommend it if your planning on keeping the truck for over 3 years and over 75k. After that is where the good preventative maintenance will start to pay you back.
