ZF TC-Tronic 12 AS 3002 TC2 Transmission Service Manual

The ZF TC-Tronic 12 AS 3002 TC2 is an automatic shift gearbox fitted to cranes and other heavy machines, and it's used on Liebherr machines. When one comes in for repair or a machine arrives with no paperwork, the person at the bench needs workshop procedures, not guesswork. This service manual is for that job. It's the complete 50-page manual, and the text is searchable, so you can jump straight to an error code or a test step.

What this manual helps you do

• Diagnose gearbox faults using the gearbox diagnosis section and the display of error codes.
• Run the test program to check how the gearbox behaves before and after a repair.
• Trace how the converter shift clutch (WSK) and the gearbox shift clutch work, so you know what you're chasing.
• Follow the notes for replacements for the automatic gearbox when a unit is being swapped.
• Check the oil cooler circuit for the converter/retarder (TC2) and the shift gearbox.

Who this is for

A crane service technician or rental fleet mechanic who repairs gearboxes in-house rather than sending every fault out. It also suits an independent repair shop working on Liebherr machines that have this transmission fitted.
