	Adding transmission oil
	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.	AS00.00-Z-0010-01A
	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.	AS00.00-Z-0005-01A
		In order to avoid damage to the transmission, always observe the Specifications for Operating Fluids!
		The transmission must be filled with transmission oil before starting the engine
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	The transmission oil pan and the overflow pipe (1) have been redesigned to optimize the oil feed of the transmission. When checking and correcting the fluid level, always note the fluid temperatures associated with the specific individual oil pan noted.
	Transmission oil pan and overflow pipe (1) modified	Only category P with transmission 722.9 as of production date 21.6.2010 with engine 113, 156, 157, 271, 272, 273, 275, 276, 278, 642, 651	BT27.10-P-0006-01W
3	Remove oil drain screw (3) and mount adapter (2) and connect oil dispenser
4	Pump 6 liters of transmission oil using oil dispenser into transmission	In order to avoid damage to the transmission, always observe the Specifications for Operating Fluids.
		On transmissions which have been repaired the quantity of transmission oil drained +0.5 liters should be poured in.

	Transmissions up to production date 18.06.2010 and all transmissions 722.9 in combination with engine 629		BB00.40-P-0236-14A
		All transmissions 722.9 as of production date 21.06.2010 except transmission 722.9 in combination with engine 629	BB00.40-P-0236-15A
5	Start engine
6	Call up the transmission fluid temperature using STAR DIAGNOSIS		AD00.00-P-2000-04A
7.1	Bring transmission oil temperature to 90 °C/194 °F	Vehicles with additional transmission oil cooler Only with previous removal/replacement of additional transmission oil cooler. Thermostat opens at 90°C/194°F. Engine speed 2500 RPM, selector lever in position "P".
7.2	Bring transmission oil temperature to 45°C/113°F	Vehicles without additional transmission oil cooler On vehicles without additional transmission oil cooler and with chamfered transmission oil pan and with white or green overflow pipe (1) the transmission oil temperature must be 45 °C/113 °F.
7.3	Bring transmission oil temperature to 35°C/95°F	Vehicles without additional transmission oil cooler On vehicles without additional transmission oil cooler and without chamfered transmission oil pan and with black overflow pipe (1) the transmission oil temperature must be 35 °C/95 °F.
8.1	Switch off engine and allow transmission oil to cool down	Vehicles with additional transmission oil cooler Only with previous removal/replacement of additional transmission oil cooler.
8.2	Turn off engine	Vehicles without additional transmission oil cooler
9	Call up the transmission fluid temperature using STAR DIAGNOSIS	On transmissions with chamfered transmission oil pan and with white or green overflow pipe (1) the transmission oil temperature must be 45 °C/113 °F.
		On transmissions without chamfered transmission oil pan and with black overflow pipe (1) the transmission oil temperature must be 35 °C/95 °F.
10	Start engine and allow to run in selector lever position "P"
11	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
12	Shift through "P-R-N-D" several times with the vehicle stationary and the engine idling
13	Allow engine to idle in selector lever position "P"
14	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 with white or green overflow pipe (1) the transmission oil temperature must be 45 °C/113 °F.
		On transmissions without chamfered transmission oil pan and with black overflow pipe (1) the transmission oil temperature must be 35 °C/95 °F.
15	Remove the adapter (2)
16	Drain off constant oil flow (arrow a) at specified transmission oil temperature, until only drops come out (refer to correct oil filling capacity (arrow b))	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. If the oil flow is not constant after opening the drain screw, the transmission oil level has to be corrected (as of operation step 11) and then adjusted again.
		On transmissions with chamfered transmission oil pan and white or green overflow pipe (1) the transmission oil temperature must be 45 °C/113 °F.
		On transmissions without chamfered transmission oil pan and black overflow pipe (1) the transmission oil temperature must be 35 °C/95 °F.
17	Replace sealing ring and screw in oil drain screw (3)		*BA27.10-P-1001-03D
18	Turn off engine
19	Lower vehicle
