Fluid Check 100,000 Mile

Hello all,

I want to start by saying I've done a lot of research on this site so I'm pretty sure I know what I need for materials but I just wanted to verify. Below is a picture of the fluids I purchased today at cut rate auto parts to do a transmission filter change and differential fluid change. My car is an 3.6L 04 and it has 98k miles on it.

Starting from left to right:

First as you can see I have Mobil 1 synthetic gear lubricant, I have 2 quarts.

Next I have Super ATF transmission fluid. I purchased 7 quarts because I was told the reservoir holds 6.2.

Next is some KW knock'er loose penetrant. I just sprayed this on the nuts for the transmission pan.

Next is GM limited slip. Now I was unsure if i needed this but I was wondering that if I don't will it hurt anything? My diff makes a good amount of noise on acceleration but from what I'm told, all of our cars do.

Finally a T45 drive bit.

Also I have a fluid transfer pump so I can easily fill the reservoirs.

Now I Just wanted to know before I continue do i have all the correct fluids? I was told to get the differential plugs i need a 10mm allen wrench, which i have.

Lastly do i need to spray the caps for both the transmission and differential with the knock'er loose? I believe my transmission has never been serviced so I don't want to strip any bolts.

Please let me know what you think. I am following the diagrams linked below:



Thank you in advance guys.

Don't put that fluid in your transmission. You NEED dexron 6!
Why is that/what's the difference?
So should I return the 7 quarts of fluid that I got?
Also what about the limited slip fluid? I checked the spare tire cover and there is no writing or anything on it. Thank you for the replies.
The bottle says "recommended for use in all domestic and import vehicles no longer under warranty where the OEM previously specified a GM DEXRON III or earlier generation DEXRON fluid"

It later says "do not use in automatic transmissions that require a GM DEXRON VI" and a couple other of fluids by ford. So what does this mean?

Is it worth it to spend the extra money and go buy some DEXRON VI?
What about the limited slip? Should I use it?

I am really sketched out about using this fluid. I wish there was just a concrete yes or no answer because the more I look the more I keep seeing both sides of the argument.
Sorry, to clarify I am sketched out about the ATF fluid. I'm going to have this car for a long time and I don't wanna wreck my tranny.
One last question, do I need to use the knock'er loose on the plugs for the transmission and the diff? The new transmission filter did not come with new plugs so I don't want to strip the bolt. Thank you for all the feedback.
