Transfer case fluid type

[dman76]

The manual says GM Automatic Transfer Case Fluid no. 12378396 but I can't find that when searching online. Is it the same as the AC Delco Auto Trak II? It is for a 2000 Tahoe.

As far as I know... AC DELCO AUTOTRAK II is the right stuff for your Transfer Case.... IF you have a NV 246
Case...
If you have the switch on your dashboard that shows... 2WD 4WD AUTO 4 HI 4 LOW then you should have a NV 246 TC... you can also crawl under your ride....and take a close look ...there is a metal shield on the TC that tells you the NUmber.

hope that helps

...forgot something you need 3 bottles ! because the "earlier " TC case need a little more than 2 quarts..
