- Connect diagnostic system.
- Observe the predefined transmission oil temperatures for the oil-level adjustment with the diagnostic system:
- Initial condition: Transmission oil temperature 30°C to 40°C.
- End condition: Transmission oil temperature 40°C to 50°C.
- Call up service function (drive).
- Carry out oil-level adjustment in accordance with instructions.
- Loosen the oil filler plug (1) using the special tool 2 405 614 .
- Top up automatic transmission fluid according to the instructions in the diagnostic system.NOTE: TECHNICAL INFORMATION
The setpoint torque deviates from the adjustable torque when using special tool 2 405 614 . - Convert setpoint torque into adjustable torque:
(setpoint torque x L1): L2 =adjustable torque
L1 = length from the center of the grip to the reversible ratchet head
L2 = length from the center of the grip up to the insertion of the special tool in the screw
- Replace the oil filler plug (1) and the sealing ring.
Parts: Oil filler plug, sealing ring
- Make sure that the special tool 2 405 614 and the torque wrench (2) align while tightening the oil filler plug (1).
- Tighten the oil filler plug (1) with the special tool 2 405 614 and the torque wrench (2).
