I've read lots of debates and opinions on flushing of automatic transmissions and the general consensus from what I see is that flushing should not be done, especially on higher mileage trannys due to the potential for seal damage, possible forcing of tranny fluid into the crankcase and other nasty things. However, the local Subaru dealer tells me they flush the transmissions and there is no filter to change.
My question is what would be the difference between your run of the mill quick change place flushing the tranny and the dealer flushing it? I know the quick change joints charge around $90 in my area and the dealer charges $200. Both use the term 'flush' and unless the dealer does something extra or better they probably use similar equipment and procedures for the job.
