General Repair Information

• The highest level of care and cleanliness along with tools that function properly are required to ensure a proper and successful transmission repair. Of course the general safety precautions also apply when carrying out repair work.
• A number of generally applicable instructions for individual repair procedures, which are otherwise mentioned at various points in the repair procedure, are summarized here. They apply to this repair information.

Guided Fault Finding  , OBD and Test Instruments

• Before servicing the transmission, determine the cause of the fault using the Vehicle Diagnostic Tester in Guided Fault Finding  , Vehicle Self-Diagnosis  and Test Instruments  .

Transmission 

• Do not run the engine and do not tow the vehicle if the transmission covers are removed or if there is no transmission fluid inside the transmission.
• Thoroughly clean the connection points and the area around them first, and then loosen them.
• When installing the transmission, make sure the alignment sleeves are seated correctly between the engine and the transmission.
• When the transmission is removed, secure the torque converter so that it cannot fall out.

Electrical Components 

Due to the electrostatic charge to the human body, a person can receive an electrostatic shock when metal objects are touched.

This charge can damage the electrical/electronic components of the transmission and the selector mechanism when touching them.

-- Touch a grounded object such as a washer fluid hose or a hoist before working on electrical/electronic components. Do not touch the connector terminal or electronic components directly.
