where does it say that gm recommends changing the fluid after 1500 miles? i just turned about 2300 on mine and i guess if helps, i probably need it done.
well, since im a race car driver :lol: i should probably change it. my dealer said they would do it under warranty. their going to put royal purple in for me though. hes a great guy :thumbsup:its in the owner's manual. couldn't give you an exact page, but it does say "for racing purposes" change the diff fluid at 1500
