Question about 2002 Chevrolet Silverado 2500HD
The chain got loose and rubbed a hole in it so I don't know what was in it.Some say autotrac 2. and some say ATF. It's a NP263XHD with pushbutton 4wheel drive . Allison trans 6.6 duramax. 3 buttons 4hi, 4lo, 2hi and no auto 4-wheel drive.
Go to DieselPlace.com and search for "pump rub". It seems there is an issue with a clip coming loose inside the Tcase and letting pieces rub a hole in the case.

Www.mygmlink.com has the answer and many more items for sale like a owners manual or service manual. I am pretty sure it is ATF though. I have not had to take mine apart nor add any fluid.
