> 2004 Endeavor Should I Change The Fluid In My Transmission?

I bought a 2004 Endeavor with 85000 miles. I am not sure if the transmission fluid has EVER been changed so I am unsure if I should change it at this point. I have hear that once you change fluid at high miles it really messes up the transmission so I am curious as to what other Endeavor owners say.

A side note and may be related. For the last couple of weeks I have noticed that whenever I am on the road and traveling say 35-65 miles per hour and go to pass someone, when I step on the gas and the car goes to downshift it starts to downshift then hesitates DRASTICALLY like it is wanting to downshift but cant. If I do not push hard on the gas it will downshift with no problems. Would a fluid change help the transmission? Any ideas what could be causing this? It just won't downshift when pushed hard. I am not abusing it, but I want to know what I could do to fix this. Anyone else have a similar problem?

fluid flush seems to be a good idea if you have that many miles on it!! what is the condition of the fluid that is in it now?

I concur with the above suggestions. When I started with Mitsubishi's all I ever heard was make sure that you flush the fluid at the recommended intervals and make sure that you only use MITSUBISHI ATF Fluid. From my research of the years Mitsubishi (trucks) transmission rarely fail unless they have the wrong fluid in them, so I personally have religiously had the Mitsubishi dealer do a complete flush at the recommended intervals. However because of the same research and advice from Manybrews I push the T-belt changes to 100k instead of the recommended 60k. We have a Lancer at 130k and an Endeavor at 116k never any issues with the tranny. The only thing I dislike on my endeavor's tranny is that the programming is so focused on fuel savings that it loves overdrive and when I want to pass (the damn lost tourist driving in the fast lane here in FL) I have to really romp it or use the manual mode to drop it to 3rd but most new cars love overdrive.
