Which transfer case fluid?

[ShawnQ]

Any idea which fluid I need for a 2007 Tahoe Z71?

The dash selector switch has 2^, auto, 4^, 4lo.

Transfer case is a NP246GM

Vehicle has stabilitrak.

Dealer sold me auto-trak II, is this correct?

Thanks In advance.
Shawn

My 08 avy took dex vi aft. The vin will tell you the correct fluid so if the dealer had that info they should have given you the correct stuff.

Auto trak II should be correct.

Auto 4WD's take Auto Trak II due to the internal clutch in the transfer case
