	Adding transmission oil
	Risk of accident  caused by vehicle starting off by itself when engine is running. Risk of injury  caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	-
	The transmission must be filled with transmission oil before starting the engine
	Risk of death  caused by vehicle slipping or toppling off of the lifting platform.	Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer.	-
1	Raise vehicle	The vehicle must be situated on the lifting platform so that it is level in both the longitudinal and transverse axes.
2	Inspecting transmission oil pan	To improve fluid supply to the transmission, the transmission oil pan and the overflow tube have been redesigned. When checking and correcting the fluid level, always note the fluid temperatures associated with the specific individual oil pan versions: ↓
		Only category P with transmission 722.901	BT27.10-P-0006-01W
		Transmission oil pan and overflow pipe modified
3	Unscrew oil drain screw (3) and mount adapter (2) and connect oil dispenser	The adapter (2) and oil dispenser can be obtained from two manufacturers. Adapter NAG 2, Flaco Gerate,
		-
4	Pump 6 liters of transmission oil using oil dispenser into transmission	In order to avoid damage to the transmission, always consult the Specifications for Operating Fluids.
		On transmissions which have been repaired the quantity of transmission oil drained +0.5 liters should be poured in.
			*BF27.00-P-1001-01C
5	Call up the transmission fluid temperature using STAR DIAGNOSIS On transmissions with chamfered transmission oil pan and white overflow pipe, the transmission oil temperature must be 40°C.
		On transmissions without chamfered transmission oil pan and with white overflow pipe, the transmission oil temperature must be 30°C.
		STAR DIAGNOSIS Compact diagnosis system for passenger cars, order number 6511 1801 00
6	Start engine and allow to run in selector lever position "P"
7	Pump transmission oil using oil dispenser into transmission	After replacing the transmission and torque converter: Pour in approx. 4 liters.
		If the torque converter has not been emptied: Pour in approx. 2 liters.
			*BF27.00-P-1001-01C
	Correct transmission fluid level
8	Shift through "P-R-N-D" several times with the vehicle stationary and the engine idling
9	Allow engine to idle in selector lever position "P"
10	Call up the transmission fluid temperature using STAR DIAGNOSIS	Because the overflow tube (1) within the oil pan is designed for operation at the specified fluid temperature, this temperature should never exceed the level indicated.
	Connect STAR DIAGNOSIS and read out fault memory		AD00.00-P-2000-04A
		On transmissions with chamfered transmission oil pan and white overflow pipe, the transmission oil temperature must be 40°C.
		On transmissions without chamfered transmission oil pan and with white overflow pipe, the transmission oil temperature must be 30°C.
11	Remove the adapter (2)
12	Allow the excess fluid (arrow a) for the indicated fluid temperature to drain, continuing until only a small flow (arrow B) emerges	It is essential that the engine be running at idle speed, and that the temperature of the transmission fluid not exceed the specified level. If the operation is carried out with the fluid at a higher temperature, too much fluid will be drained.
		For transmissions with chamfered transmission oil pan and white overflow pipe the transmission oil temperature must be 40°C.
		For transmissions with chamfered transmission oil pan and black overflow pipe the transmission oil temperature must be 30°C.
13	Replace sealing ring and screw in oil drain screw (3)		*BA27.10-P-1001-03A
14	Turn off engine
15	Lower vehicle
