The last Motorcraft battery lasted 2 years and 2 months. Also the deaker suggested a tranny flush for nearly $300., brake line flush, and a radiator flush which is due according to the manual. Is the tranny flush and brake line flush overkill?
With a tranny flush you increase the chances of debris getting stuck in the valve body. That would be a pass from me. I would say call a ATRA member shop for a price for a fluid drain (and assume filter replaced).
Brake line flushes only flush your wallet. If you are past 100k miles ask them how much to bleed out the old fluid with new fluid. If you get another brake job before 100k.. ask the technician to bleed out the old fluid (and add new fluid) when they do the brake job. I assume it won't be too much. Radiator flush won't do much more than a simple drain and refill. I am not sure how long the anti freeze is suppose to last.
