Repair process
Intake inspection and diagnostics — with a genuine ZF Testman or Voith diagnostic tool
Disassembly — to factory procedures, with the right special tools
Component assessment — every part is inspected and we decide: repair, replace or reuse
Repair / reassembly — only genuine OEM parts from ZF and Voith
Testing — measurement and checks after reassembly, before handover
Documentation — you receive a full report on the repair, the parts used and the test results
Why the right repair costs less
An incorrect repair — with non-genuine parts or without factory tools — usually means a second repair within 2–3 months. We do it once, properly, and you get the gearbox back as good as new, with 0 km.
