Re: Transmission Oil
I changed mine at 80K. I bought the truck used with 60K on it and by the looks of the hitch (chain hook area and receiver) and evidence that a brake controller was installed and removed... I'm pretty sure it did a lot of trailer pulling. I'm at 135K now and wondering if I should just leave it until it blows (hopefully long after I trade it in) or change it. It still shifts great.
