I'm sorry, but I don't buy the argument against changing the fluid. Any failures were probably coincidental or were going to happen soon anyways (like switching to synthetic engine oil). I've never believed standard transmission fluid could last the life of a vehicle. I figure a tranny flush should be done roughly as often as the timing belt. Longer if you use synthetic.

If you don't want to pay for a fancy machine back flush just drain what you can and refill it. It's at least half of it is new and has the proper lubrication and viscocity then.
