Fig. Fig. 1: Before refilling the manual transmission, decide which temperature span will be encountered until the next transmission fluid change-except B-W T5R and NV1500 transmissions

In the earlier models (1981-90 vehicles), the manual transmission/transfer case is a complete unit and the fluid from the transmission lubricates the transfer case. On newer vehicles, the transfer case and the transmission have separate fluid systems which require separate draining and refilling. Use engine oil to refill the transfer case. Refer to the oil viscosity chart in the manual transmission section.

Although automatic transmissions use Automatic Transmission Fluid (ATF), transfer cases utilize the same engine oil as do manual transmissions.

LEVEL CHECK

1981-90 Manual Transmission/Transfer Cases

Since these transfer cases share the fluid with the transmissions, refer to the manual transmission procedures earlier in this section.

Automatic Transmission and 1991-96 Manual Transmisison Transfer Cases

See Figure 2

To check the level of the transfer case fluid, regardless of whether it is attached to an automatic or manual transmission, perform the following:

  1. If necessary for access, raise and safely support the vehicle on jackstands as level as possible.
  2.  


CAUTION
If the vehicle was just driven, the fluid may be very hot; be careful when checking the fluid with your finger.

Fig. Fig. 2: The filler plug on the transfer case is located on the upper right-hand side of the assembly

  1. Open the fluid fill plug and feel inside the fill plug opening with your finger. The fluid should come to the bottom edge of the hole.
  2.  
  3. If the level is satisfactory, reinstall the plug and tighten it securely.
  4.  
  5. Otherwise, add fluid through the fill plug hole until it begins to run out of the hole. Reinstall the plug securely.
  6.  
  7. Lower the vehicle, if necessary.
  8.  

DRAIN AND REFILL



  1. Raise the vehicle and support safely with jackstands. Place a catch pan under the transfer case.
  2.  
  3. Remove the filler plug from the transfer case.
  4.  
  5. Remove the drain plug at the bottom of the transfer case. Allow all of the fluid to drain into the pan.
  6.  
  7. Install the drain plug to 20 ft. lbs. (27 Nm).
  8.  
  9. Refill the transfer case with the proper amount and type of engine oil. Install the fill plug and torque to 20 ft. lbs. (26 Nm).
  10.
