Main dimensions (in millimeters)
The mass of the transfer case without oil is 40.30 kg, and with oil - 41.55 kg. 1500 ml±2% of oil must be poured into an empty box.
The transfer case uses Shell TF 0753 oil, which was specially developed by Magna Steyr and Shell. The oil contains special additives that improve the operation of the transfer case. No other oil must be used in the transfer case.
When installing or reinstalling the transfer case, the splines of the input shaft must be lubricated with a special anti-seize grease "Weicon anti-seize montagepaste grau TL 7391".

Diagnostics
The transfer case control module is capable of storing fault codes that can be read using the T4 tool or any other diagnostic tool that uses the KW2000* protocol.
This information is transmitted via the diagnostic socket.
The diagnostic connector allows the various control modules connected to the buses to communicate with the T4 or other suitable diagnostic tool. The data is sent to the connector via the CAN bus. This allows diagnostic information to be read and various functions to be programmed using the T4 or other suitable diagnostic tool.
Transfer Case Control Module Uses Diagnostic Trouble Codes (DTC), which correspond to malfunctions in the electrical circuits of the transfer case.
Shift and Clutch Calibration
In order for the range shift mechanism to function correctly, the transfer case control module must be calibrated to match the dimensions of the transfer case it is connected to.
This calibration must be performed in the following cases:
- When replacing the switch
- When replacing the transfer box control module
- When replacing a transfer case or selected range sensor
- In the event that a malfunction in the vehicle or the transfer case control module has resulted in an uncertainty in the range of the transfer case.
The procedure for setting the transmission mechanism of a manual transmission
The transfer case control module is capable of self-tuning, which allows it to determine which gear the driver has selected. In any of the following cases, the self-tuning parameters must be initialized by performing the transmission tuning procedure:
- If the transfer case control module is reprogrammed or replaced
- If the manual transmission has been replaced
- If the gear position sensor has been replaced
Transmission setting procedure
- If transmission tuning is due to replacement of a manual transmission or gear position sensor, use the T4 tool to set the transmission tuning status in the transfer case control module to 0.
- Get the car moving.
- While reversing, take your foot completely off the clutch pedal for 3 seconds and check that the R symbol is displayed on the instrument panel.
- While driving in 1st gear, wait for the 1st gear indication on the instrument panel and shift into the next gear. While driving, shift into higher gears as soon as the current gear is displayed on the instrument panel until you reach 6th gear, then stop the vehicle.
- Stop the engine, remove the ignition key and wait at least 60 seconds (to turn off power to the transfer box control module).
- Insert the ignition key and turn the ignition switch to position II (ignition).
- Select each gear in turn. If the corresponding gear is displayed on the instrument panel immediately after each gear is selected, the gear setting procedure has been completed successfully. If the gear position is not displayed on the instrument panel, the gear adjustment procedure was not completed successfully and must be repeated.
NOTE: The T4 can also be used to verify that the gear set up procedure was completed successfully.
