| Notes relating to the 09G 6 speed automatic gearbox |
| The 09G automatic gearbox is equipped with 6 forward gears controlled hydraulically. The gears 2, 3, 4, 5 and 6 are engaged mechanically when the converter cancelling clutch is closed thus avoiding converter slipping. |
| The torque converter is equipped with a torque cancelling clutch. The torque converter cancelling clutch closes depending on the load and the speed. |
| The ATF in the gearbox is a long-life liquid. It does not need to be changed during routine maintenance. |
| The ATF levels in the planetary gears and the final drive are verified and topped up at the same time → Chapter. |
| t
| For the 09G automatic gearbox, only the ATF supplied as spare must be used. Other oils cause problems or even faults in the gearbox; ATF spare number → Chapter. |
| Before carrying out repairs on the automatic gearbox, the cause of the fault must be determined using “Guided fault finding”. |
| “Guided fault finding” is carried out using the diagnosis centre -VAS 505X-. |
| Modifications in the shift points, up and down |
| When shifting up or down, the gearshifts are automaticlly selected using the possible range of gear shifts according to the position of the accelerator pedal and the speed of travel. |
| t
| The possible range of a gear change will be adapted for maximum engine power during extreme ascents. |
| t
| The possible range of a gear change will be adapted for maximum engine braking power during extreme descents |
| t
| The engine braking effect may be used by directly selecting a specific gear using the Tiptronic, for example, when driving with a trailer on slopes. |
