Main dimensions (in millimeters)
The weight of the transfer case without oil is 40.30 kg, and with oil - 41.55 kg. It is necessary to pour 1500 ml ±2% oil into the 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 should 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 in its memory, which can be read using the T4 tool or any other diagnostic tool using the KW2000 protocol*.
This information is transmitted via the diagnostic connector.
The diagnostic connector enables various control modules connected to the buses to communicate with the T4 device or another suitable diagnostic tool. The data is transmitted to the connector via the CAN bus. This allows reading diagnostic information and programming various functions using the T4 device or another suitable diagnostic tool.
The transfer case control module uses diagnostic trouble codes (DTCs) that correspond to malfunctions in the transfer case electrical circuits.
Calibration of the range shift mechanism and clutch
In order for the range shift mechanism to function properly, the transfer case control module must be calibrated to the dimensions of the transfer case to which it is connected.
This calibration must be performed in the following cases:
- When replacing the switch
- When replacing the transfer case control module
- When replacing the transfer case or the selected range sensor
- In the event that a fault in the vehicle or the transfer case control module has resulted in the transfer case range being undefined.
Procedure for adjusting the transmission mechanism of a manual gearbox
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 transfer case setup 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
The procedure for adjusting the transmission mechanism
- If the transmission learning is performed due to replacement of the manual transmission or gear position sensor, use the T4 tool to set the transmission learning status in the transfer case control module to 0.
- Set the car in motion.
- When reversing, completely remove your foot from the clutch pedal for 3 seconds and check that the R symbol is displayed on the instrument panel.
- While driving in 1st gear, wait until gear 1 is displayed on the instrument cluster and shift to the next gear. While driving, shift to higher gears immediately after the current gear is displayed on the instrument cluster until you reach 6th gear, then stop the car.
- Stop the engine, remove the ignition key and wait at least 60 seconds. (to turn off the power supply to the transfer case 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 cluster immediately after each gear is selected, the gear adjustment procedure has been completed successfully. If the gear position is not displayed on the instrument cluster, the gear adjustment procedure has not been completed successfully and must be repeated.
NOTE: The T4 tool can also be used to verify that the transmission adjustment procedure has been completed successfully.
