No Fuel filter on this truck.
Dump a can of BG44K in the tank and move on.
Trans service isnt until 150K, but I'd do it at 100K as a precaution, earlier if you use this thing to creep in rush hour traffic.
Wait...what?! For real? Seems a bit risky to me.
On a somewhat related note, why wait for 100K on the trans fluid? I seem to remember one of my engineering profs (think it was Bollfrass) that said that the majority of gear wear occurs in the first 5-10k miles. Why not change at that point so you don't have those particles in the fluid for another 90k?
There's a strainer in the tank, that's it.
GM deleted their inline fuel filters in the early 2000s because people weren't changing them and causing fuel pump failures, as well as a cost cutting measure.
Ford followed suit in the mid/late 2000s in their gasoline applications.
The transmission has a filter in it, so I don't see a reason to change it that often. You may want to consider doing it more often if you are towing, running in extreme temps, or using the vehicle as an uber or delivery type setting.
The main enemy of trans fluid is heat. It breaks down the fluid and uses up the additive package. Replenishing a portion of the fluid at a time (vs Flushing it) will renew the additives and replace some of the 'worn' fluid. I personally change my vehicles trans fluids at 60K as a precautionary measure.
Once when my dads company did away with company cars, he bought a used maxima with 100K. The car shifted really firmly and if you did a kickdown from 4th to 3rd, it would be really rough. The trans fluid was pretty dirty, so he would drain 2 or 3 quarts from the transmission once a month, refill and drive it.
This went on for 4 or 5 months and the fluid was looking nice and fresh and the trans was shifting nicely. Anecdotal but a good example.
