What type of fluid do i use in my transfer case


If you have the manual transfer case (lever actuated), use DEXRON-III Automatic Transmission Fluid. If you have an automatic transfer case (push button actuated), you should use the fluid that GM recommends. Some owners' manuals may say to use Automatic Transfer Case Fluid (GM Part No. 12378396), which is a reddish colored fluid. GM has a new Auto Trak II Transfer Case Fluid (GM Part No. 12378508), which has a bluish color to it. The newer fluid has better friction modifiers. While your doing the job, it's a good idea to change the drain and fill plugs (GM Part No. 15032997) out too.

Ned to change the oil in transfer case


The Z71 typically comes with the auto 4wd transfer case (cannot remember the GM number). This requires AutoTrak II, which is available at a GM dealer. Do not use any other fluid in this transfer case! The previous post was correct in the location of the two plugs, but not on the fluid (the other types of transfer cases by GM use ATF). The transfer case is located under the truck right under the cab. There is a small skid plate under it, and a large driveshaft leaves the rear end of the case heading to the rear differential (axle). If you have the manual or electronic w/o auto 4WD transfer case, you can use Dexron III, but Dexron VI is a better fluid that is also now available at your local auto parts store. Again, if you have the AUTO 4WD button in the dash, use the AutoTrak II fluid from the dealer.
