What kind of oil should be added to the transfer case?

[OLucia]

The transfer case should be filled with ATF (Automatic Transmission Fluid). Below is relevant information about transfer cases: 1. Judging from the gear lever of the transfer case, it more closely resembles a traditional part-time four-wheel drive system. The difference is that it is equipped with a center differential. When 4H is engaged, it can not only drive at high speeds on gravel roads but also achieve the function of four-wheel drive on regular highways. The 4HLC and 4LLC options it provides are four-wheel drive modes with the center differential lock engaged. At this point, its functions are the same as the 4H and 4L of a part-time four-wheel drive system. 2. The transfer case is a device that distributes the engine's power, directing it to the rear axle or simultaneously to both the front and rear axles.
