A fluid matching the properties and performance characteristics of Auto-Trak II fluid is essential for the proper function and longevity of specific transfer cases, particularly those found in General Motors vehicles. This compatibility ensures the transfer case receives the lubrication and friction modification necessary for smooth operation and protection against wear. An example would be a commercially available fluid, meticulously formulated to meet or exceed the original equipment manufacturers (OEM) specifications for Auto-Trak II, thereby providing a suitable alternative.
The importance of utilizing a fluid designed to function similarly to Auto-Trak II stems from the unique engineering of the transfer cases it serves. These transfer cases often incorporate specific friction materials and require precise friction characteristics in the fluid to enable proper clutch engagement and disengagement. Deviating from these specifications can lead to shuddering, noise, premature wear, and ultimately, transfer case failure. Understanding the historical context of Auto-Trak II is also relevant; it was specifically developed for certain GM vehicles, and its properties were carefully considered during the vehicle design phase, leading to substantial benefits in the form of improved durability and shift quality.
