Does the ELSD take a different fluid than the MLSD?
I'm looking at 3-4 different part numbers on this fluid which I cannot decipher the difference

GM does a great job with giving me a headache

GM makes a lot of different vehicles...

ACDelco 10-4034 (GM 88862624 in US, 88862625 in CA) is for our cars.

ACDelco 10-4016 is what my 4th gen trans am takes.

The information is in the owner's manual. Page 329 in the 2019 manual. Might be a different page for different model year.
