Have a 08 grand cherokee with Diesel engine can I use Atf4 for transfer case??
I see no reason you can't to up grade to 4, if your jeep already has atf in the case. But if it came from jeep with gear lube in there keep it in there.
The AWD will fail if you use that, Chrysler makes a special fluid for the transfer case for AWD Jeeps as well as a special fluid for the differentials, so stick with the factory stuff for now, I saw a article somewhere that pennzoil is looking into making something for AWD Jeeps down the road but nothing right now.
