AT Transmission Flush

AT Transmission Flush
Ok, I have read everything on this board that I could search for on this issue. I just hit the 100k mark and bought the car at 41k miles. I know that since I bought it, I never had the AT flush done. Some say to leave it alone at this mileage? It's a 2000 Max SE
When I pull up to work I can smell a small rotten egg smell coming from my car. Not sure what it is but with some saying "burnt" smell, could that be it? I am thinking of calling the Nissan dealership and checking the owner’s manual when I go to lunch to see what they recommend for it but wanted to ask the board as well your thoughts?
A. Should I replace the AT fluid, why or why not?
B. What could the rotten egg smell be?

I want to have it flushed because I agree that MNT is very important. Another one on here said their tranny died a week after the flush and he had high mileage, that made me think if it's not broken don't fix it. If you guys think I will be ok, I would love nothing more then to set up the appt to get it done today.
How would I check the CAT to see if that is the problem? Now that you mention it, I think it is but is there a way to know for sure?

The reason you shouldn't flush an automatic transmission when it hasn't been flushed before for a long time, is that the old ATF has broken down, relying on the saturated metal particles to create friction for the gear plates. The metal particles are extremely abrasive and create large variances between plates.
Once flushed, these metal particles that were suspended in the old, broken down ATF is now gone. The transmission plates no longer functioning normally due to the metal particles being gone.
At 100k miles, I think flushing is still fine.

he may just need to take it for a long ride and romp on it a little to burn the **** off/out of it....have it check before replacing anything...if there is no ses light on have hte car scaned anyway because the light may be out.
no need spending allkinds of money if there is the chance you don't need to.

now the cat is bad which is obvious from the smell.
fixing the mixture wont repair the cat.

I still didn't hear a response and I might as well do this if I need a new CAT...
Is the Warpspeed still the best way to go for the y-pipe? I remember searching for this 2 years ago and coming to that conclusion for the price. How does this look?

your problem is probably with the main cat (after the ypipe)

A. Yes, I would drain the fluid, replace the filter (should come with a new gasket), clean the pan (there 100K worth of stuff in there), replace the fluid. You will need about 6 qts of fluid.
2. Sounds like you need a new CAT. I have an OEM cat if you interested?

i would just drop the 19 mm plug, then add 4 litres of fluid. Worm it up go through the gears twice and recheck level. Then if you wish you can do it again soon after. You don't have to change these filters. They're metallic type and every tranny i seen unless completely shot there is rarely any debris or not enough to block the flow. These filter medias must be 2x4 inches wide.

^^Do what he says its the best flush to go with also the maxima AT tranny has about 10 quarts of fluid in it when you just unscrew the plug you should get out about 5 quarts. You can also drop the pan and change the filter it wont hurt
