i mostly agree.. i just know that nice fresh oil is good for systems.. breaking, tranny, engine, etc.. the oil is there for a reason.. nissan maint schedule calls for trans case oil inspect/ replacement at 36k miles. since the trans case is built into the tranny, i did both. my mechanic is my cousin who i trust.. he advised me to do it.. i did it, and after the fact, he said it was a good idea. so its a great recomendation if you plan on keeping your car and want it to run smooth.
additionally, my cousin always jokes that when cars come in w/ problems, 9 times out of 10, the problem could have been avoided if the owner followed main. schedule. we all, myself included, think those things are scams and dealers want out $$.. but not that i actually keep my cars for year and years, i change my thinking and try and keep the maint up to date.
but yes, more often than not, the car will be ok for years.. even if you dont change your fluids...
