Does the G M stuff fix the chatter or will Amzoil be better?

I went with Amsoil full synth rear diff fluid as well, at the recommendation of Rich at Abel Chevrolet.

MlwYlw, if you are referring to the lubricant for your rear axle / differential then you need 3 quarts of this: 88862624 DEXRON® LS Gear Oil.

Did you have to add friction modifier? Amsoil site states works with most LSDs but some need modifer. Thanks.

Yes, Abel Chevrolet put friction modifier in when they changed the rear diff fluid with Amsoil in my 17 GS.

If you use the GM product, you do not add modifier...it is already in there.
