Yes, we do have a sort of filter. Trust me, I saw every step of my tranny build and we replaced the filter. It was covered in clutch material.
It is right below the brake band in that picture. It attaches right to the valve body. Now, the average G35 probably doesn't need that replaced, but my valve body was messed up and I had clutch material everywhere. When we took it off it was filthy.

No, what I posted has nothing to do with the Transgo kit. That is from a overhaul kit for our transmission.

A flush isn't necessary. The Nissan and Infiniti dealers in Kansas City don't do flushes with machines any more because the word from Nissan is it causes more problems. Additionally, all these shops say they simply drain the tranny every 30K miles even though Nissan really doesn't require a change until 60 or 70K miles.
A tranny fluid change will get you 3.1 QTs (measured myself). I didn't change my fluid until 60K miles. I bought 9 QTs of J-matic. Drained the tranny. Drove for 100 miles. Drained the tranny. Drove for another 100 miles. Drained the tranny. On every change, the fluid got pinker. Even after 60K miles and some decently hard driving on occasion, my G's fluid looked pretty good. I plan on draining the tranny every 30K miles and replacing with 3.1 QTs.
Note* If your G is shifting odd, replacing the fluid isn't going to fix the problem. There's something else going on.

If you're not sure or uncomfortable with doing the ATF per the shop manual, do it the "Honda way" as outlined above.. It's probably easier since you don't have to disconnect anything.. Good luck!

If a 1x drain/refill is done, probably just enough new ATF is put back into the system to keep it going until the next drain/refill.
The Honda method of doing a drain/refill 3 times, you're basically replacing about 80% of the ATF, so most of the ATF in your AT is new fluid.. Note that in the 07 FSM Infiniti says to inspect every year or 15K miles and replace as necessary. If you're fanatical about the car, you may want to just do a 1x drain/refill once a year..
