1 General Information
Apart from the shift speed charts, the hydraulic and mechanical diagnosis for the Hydra-matic 4L60-E automatic
transmission fitted to MY2004 AWD Wagon models, carries over from MY 2003 VY and V2 Series vehicles. Therefore,
apart from the shift speed charts contained in this Section, refer to Section 7C3 Automatic Transmission
Hydraulic/Mechanical Diagnosis, in the MY 2003 VY and V2 Series Service Information, for all other hydraulic and
mechanical diagnosis.
