- 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 using an appropriate scan tool.TECHNICAL DATA SPECIFICATION
GA8HP51Z transmission capacity min. 9.28 L TECHNICAL DATA SPECIFICATIONGA8HP76Z transmission capacity min. 9.35 L NOTE: TECHNICAL INFORMATION
The setpoint torque deviates from the adjustable torque when using special tool 2 405 614. - Converting the setpoint torque into the 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 handle to the engaging of the special tool in the bolt
- 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).
