How many miles on your Liberty? Yes, that is sort of high $, but if doing it yourself is not an option, then it may be the way to go while still under warranty. So they are actually going to drop the pan, change the filter, and then flush the rest of the old fluid out as well? Sorry, I just have never had heard of any shops ever doing the whole deal like that. Most will either drop the pan and filter and then simply refill, or take the cooler lines loose and do a complete flush with out dropping the pan. Given a choice, I would take the flush with all new fluid any day. Maybe for that price you are getting both services (hopefully). It only holds like 9 qts total.
