All of them are rated for temperatures that are far beyond what your transmission is going to heat up to. They all have detergents to help wet clutch life that your transmission doesn't have in it. I would bet money you could fill it with diesel instead of atf and the car would drive the same.
Fun fact on that is when i was in Cummins training when i worked at dodge i found out you can run diesel engines on ATF you just need to run about 10% diesel in the ATF because ATF alone wont lubricate the injectors enough.

This post is completely false, misguided and its info like this that gives forums a bad name. Admins should delete this drivel.
The A10 and the TR6060 transmissions are designed with specific fluid viscosities and hydraulic compressibility for the transmission to shift, function and not put the car into limp mode immediately. Deviations from this formula are critical and if you wish to roll the dice with a >$7500 USED price for a transmission, go for it!
The OEM GM fluids are junk. Mobil1 is in the same trash can as both products, along with WalMart SuperTech come from the same base stocks in Texas. DEXOS is only a bare minimum additive schedule... so if you actually want to preserve your drivetrain, spend a few dollars more and buy quality products designed to actually perform and are test-proven on the track.
My ZLE has 14,630 actual track miles and is driven daily at times with 37,000 total miles. I use Amsoil 15w-50 racing oil exclusively, not switching between an EPA/GM scam to use a lighter oil on the street. I still can get 24mph HWY cruise on a roadtrip without taking any chances.
Changing the ATF in the A10 or M6 will protect it better and improve cooling dramatically!
The eLSD receives a severe amount of heat through the tunnel, enough to shut off any GoPro mounted to the rear bumper within 7-9 minutes of operation. Using cheap GM gear lube is not recommended for any other use I can think of with a ZL1.
As someone who did testing for RP Oils with their Parent company Synerlec decades ago in a full-tilt-boogie Texas World Speedway 7-day nonstop lapping session... Their racing fluids are simply unmatched in quality and the highest prices, but their consumer O'Reilly branded stuff is no better than Pennzoil store products.
