Eric:
In the owner's manual and in my Duramax supplement both call out GM part number 88958860 and the 'only' fluid to use in the hydraulic clutch.
The problem is you cannot get the fluid. I have tried several dealerships and even called the GMC owner assistance line and the part is just not available, although it is in the system.
What are you using for the hydraulic clutch? I need to know as the fluid level in my reservoir is down to 'Min'.
Thanks
