Oh my gosh, the oil though? :lol: That's insane. I didn't change the oil on a motorcycle I had and it blew up while I was riding it...I'm guessing it was related!Opinions will vary. I knew an old guy when I was a teenager that never changed the oil in his cars or trucks. Just the filter. His logic was that oil cannot be broken down. Must admit, his old Datsun truck was still running when he died. Didn't smoke either. Go figure.
Many people don't believe in changing transmission, rear end, power steering, brake fluids. They just drive it till it needs a new whatever.
Not that I know of. And I do know this transmission very thoroughly.but he claims it not just a simple filter change, something about valve body connected with filter?
That's just totally wrong. He does not know what he's talking about. Oil viscosity gets lower as the oil is subjected to shear inside an engine and trans. Oil (both engine and trans, though more so in the engine) gets contaminated. The filter CANNOT remove dissolved contaminants. Additives wear out. New filters do not replace the additives. He is VERY ignorant about modern oils.His logic was that oil cannot be broken down.
That's VERY true.Many people don't believe in changing transmission, rear end, power steering, brake fluids. They just drive it till it needs a new whatever.
Old thread ... but regarding this external filter, do you still need to have the internal filter after you install this external one?Not sure what the manual says but I am a proponent of servicing the tranny at least every 25k and every 20k if you tow alot. For your first tranny service I would drop the pan, change the filter and refill, all at the Ford dealer so it shows up on your CarQuest and will keep your warranty in place. I also added an external tranny spin-on filter from Summit Racing; at about $40 it is a great option which will eliminate the need for an internal filter change in future flushes.
