	Removing
	Risk of injury  to skin or eyes caused by hydraulic fluid spraying out under high pressure. Risk of poisoning  caused by swallowing hydraulic fluid.	Depressurize the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses.	AS00.00-Z-0013-01A
	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
	Risk of injury  to skin and eyes caused by handling hot or glowing objects.	Wear safety gloves, protective clothing and safety glasses, if necessary.	AS00.00-Z-0002-01A
	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
	General information	Note different transmission fluid temperatures when checking and correcting the level of the transmission fluid.
1	Remove rear section from engine compartment paneling or lower soundproofing
	Checking
2	Inspecting transmission oil pan	Vehicles with transmission 722.901
		The transmission oil pan and the overflow pipe (1) have been redesigned to optimize the oil supply of the transmission. When checking and correcting the fluid level, always note the fluid temperatures associated with the specific individual oil pan versions: ↓
		Transmission oil pan and overflow pipe modified	BT27.10-P-0006-01W
	Check transmission fluid level
3	Start the engine, then allow it to idle and maintain pressure on the brake pedal while shifting the transmission through the ranges "PR- N-D"
4	Call up the transmission fluid temperature using STAR DIAGNOSIS	On transmissions with chamfered transmission oil pan (white overflow pipe), the transmission oil temperature must be 45°C  .
		On transmissions without chamfered transmission oil pan (black overflow pipe), the transmission oil temperature must be 35°C  .
5	Allow the engine to run in selector lever position "P"	The engine must run at idle speed and each specified transmission oil temperature must be adhered to. A lower transmission oil temperature causes measuring errors
		On transmissions with chamfered transmission oil pan (white overflow pipe), the transmission oil temperature must be 45°C  .
		On transmissions without chamfered transmission oil pan (black overflow pipe), the transmission oil temperature must be 35°C  .
6	Carefully unscrew the oil drain screw (3) from the transmission's oil pan and observe the fluid as it emerges, then screw the oil drain screw (3) back in immediately	With an oil flow of thickness (arrow a) or thickness (arrow b) the transmission oil level is OK and does not have to be corrected. With an oil flow of thickness (arrow c) the transmission oil level must be corrected and in addition must be checked again.

7	Turn off engine
	Correct transmission oil level (after check)
8	Start engine and allow to run at idle speed in selector lever position "P"
9	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.
		On transmissions with chamfered transmission oil pan (white overflow pipe), the transmission oil temperature must be 45°C  .
		On transmissions without chamfered transmission oil pan (black overflow pipe), the transmission oil temperature must be 35°C  .
10	Mount adapter (2) and connect transmission oil filler	Adapter and transmission oil filler (NAT 2), see GOTIS
		http://gotis.aftersales.daimlerchrysler.com
11	Shift through the drive positions "P-R-N-D" several times when the brake is actuated and the engine is at idle speed
12	Pump 1 l transmission oil using filling pump into transmission	Always observe work procedure and Specifications for Operating Fluids, otherwise transmission will be damaged.
			*BF27.00-P-1001-01C
13	Remove the adapter (2)
14	Allow the excess fluid for the indicated fluid temperature to drain, continuing until only a small flow (arrow B) emerges	The engine must run at idle speed and the specified transmission oil temperature must be reached in each case, too much transmission oil is drained at a higher transmission oil temperature.
		On transmissions with chamfered transmission oil pan (white overflow pipe), the transmission oil temperature must be 45°C  .
		On transmissions without chamfered transmission oil pan (black overflow pipe), the transmission oil temperature must be 35°C  .
15	Replace sealing ring and screw in oil drain screw (3)		*BA27.10-P-1001-03A
16	Turn off engine
	Install
17	Install rear section of engine compartment paneling or lower soundproofing
