Have 30,000 miles on car. My desire to flush/replace trans fluid at this mileage is based on what I've read and what I've experienced in HPDE's with our Corvette. Roughly 75% of of the material (iron, steel, clutch disc dust, etc.) that a new auto trans will shed occurs in the first 10,000 miles or so. If a person does a flush/filter change early in the life of an auto trans, durability is greatly enhanced. We do not have "lifetime" fluids. Our transmissions require service, according to my local dealer, at around 100,000 miles. I don't think we have disposable trans filters. Rather we have a screen that needs to be removed, cleaned and replaced. My issue is with the cost of the fluid. If there is a suitable Shell product that costs less, it would be worth considering. The dealer position that the fluid costs so much because it is full synthetic is just silly. Amsoil and Mobil1 are both full synthetic and sell for 1/4 the price. So, is this a case of Chrysler charging as much as they can get away with until reputable aftermarket products become available? It sure seems like it to me...
