Anyone have official torque specs for the plugs?

Anyone try this stuff?
BG is supposed to be top notch material, especially for such LSD and other gear applications.
Have a look:

Another option, is to get the LS/D concentrate MGC separately and mix with P/N 750

Would you guys recommend changing the diff fluid as an essential item at 1500 miles? Dealership down here in HI is saying that it's only a 100k service item and is questioning why I would want it done.

100 percent absolutely. Its cheap insurance...

I changed mine at 1500 miles (super dirty!) and just did it again at 3,500 miles and it was filthy again (5 track days within that time also).

Thanks for the advice.

Feeling like that the Dealership Service Dept I am working with is somewhat on the price gouging side -- they are asking $375 for the diff fluid change -- from the description of the job itself, that seems a bit on the high side.

Very much so. The entire job took me 20 minutes.

Yep do it yourself. I had a look under the car last week, everything is easily accessible. I will be doing mine this weekend.

100000% do it yourself. I will shamefully admit before the 1LE I had never even changed my own oil. Track prep for me included an oil/filter change, diff fluid, and brake fluid swap. Did all this with my buddies help in an hour (rented a 2 post lift for $20 which made everything stupid easy) Absolutely no reason to pay a dealer for this service. Mine wanted 160 for just the differential. For me all fluids I mentioned above, the fluid transfer pump, and the lift was under $200 total. If I can do it, anyone can lol. I also did my first diff fluid swap at around 3500 miles and it was filthy and the plugs were covered in sludge like everyone else that has posted pics. Something else worth mentioning was that I couldn't believe how dark my oil was after only a couple thousand daily driven miles (after the initial break in oil change).....like it was almost black. Very glad I changed it when I did

Not a 1LE but you want to be on flat ground when doing this so this is how I decided to do it. I used the slope of my driveway and ramps to level it so I could get under. Like others said, it's about as easy as it gets.

Also, I got the fluid from a GM parts department for much cheaper than Amazon. See if they'll give you wholesale pricing.

How often is everyone doing transmission fluid?

I plan on doing a track day or 3 right after my 1500 mi, so I was going to do oil and diff, but maybe tranny as well if its required?

[SS 1LE]

Can a mod please make this a sticky?

[SS 1LE]

Officially a sticky!
