AT Transmission Fluid Replacement

Note this is only for the 2004-2005 4 speed automatics. People keep forgetting Mazda did a big mechanical upgrade to the RX-8 in 2006 by putting in the 6 speed automatic with the 6 port engine. Th 6 speed auto takes Mobil 3309. I use castrol multi vehicle import, works great.

Bump.
I'm having issues with dealership recommendations on 2006 RX8 Shinka AT transmission fluid flush recommendations. The dealership I'm currently having my car worked on recommended the flush at the same time they swapped out the rear diff fluid (the rear diff was getting pretty bad at 76000 miles that I was dragging a tire around corners even at low speeds). After they changed the rear diff they called and informed me they were unable to power flush it due to it lacking a dipstick or something and said I would have to look elsewhere.
WTF! It's a Mazda vehicle at a Mazda dealership. Mind blown. I would have no issue doing it myself but I'm in a small apartment in the middle of the city at the moment and have no equipment or space to do so.
I called a second dealership in the area and he said he doesn't recommend EVER changing the fully synthetic fluid unless there are serious transmission issues. He quoted longetivity of the fluid as well as expense of the synthetic requirements.
My rear diff issue is mostly resolved, however the transmission is a little rough in shifting. Especially at startup. And oddly, a noise can be heard coming from the engine/transmission area sounding like a rhythmic soft knock when not in neutral or park.
Any ideas recommendations for my conflict?

Scare tactics! (real or no?)
I have a 2005 w/ a 4-sp automatic. Bought the car two years ago with 5K. Lots of highway miles since, and I am at 65K.
I don't have any tranny issues, but I want to make sure I don't in the future, as I plan to keep the car a long time. When I talked to a Mazda dealer tech, he STRONGLY advised against doing anything except topping off the fluid. He said he's heard of full flush jobs ruining these transmissions, that the new fluid has a lot more detergents, and he would never do the job for fear of liability concerns. I asked him about dropping the pan and replacing it that way, and he again advised against it.
Not doing preventative maintenance - I don't like the sound of that. But I dislike the sound of needing a new transmission even more.
What do you guys think?

Ruined Xmsn
^^^I agree with these guys. Please disregard my previous post. This sound just happened to manifest after doing my xmsn flush. The noise became more pronounced and I can hear it better under the hood. It's the SSV and I got a pending code P0207 which confirms said noise.
The xmsn is shifting VERY smooth! Red Line D4 ATF highly recommended. Don't let them scare you. DIY, it's really not that difficult. Make sure you flush the xmsn cooler on the bottom of the radiator. I didn't do it but I'm replacing my radiator....not b/c of the flush, I'm having cooling issues.
Best of luck!

Did removing/cleaning the SSV solve your issue with the engine noise outside of Park/Neutral?

Awaiting parts
Right on, I'm gonna order 12 quarts of Castrol Multi Vehicle Import (for the 2006 6spd automatic) and either do it myself or take it to some oil change place that can flush it properly.

Got my tranny flushed today at another dealer who didn't hesitate to do the work. Wasn't cheap - $190 - but the car shifts better now and I know I've extended the life of my transmission. Thanks everyone for putting me at ease; really glad this is done now.

Where is the fill plug
If your fluid has any brown look and is not bright red it's a good idea to change. I changed mine at about 35K it cost less then twenty bucks. My son has one of those containers(I think it was 30-40 dollars) that sucks it out from the transmission dip stick tube. It was fast and even though it does not get all the fluid out(nothing does just like an oil change). The color was much better after that and I'll do it sooner next time. Here is a "TSB" about how Mazda wants it done.
