In the diagnosis have a typical error for the automatic transmission 17090 - sensor selector F125.
It was decided to remove the rear cover and automatic self control and perform a thorough renovation.

Before that, it was purchased the original oil G052 180 A2 in the amount of 5 liters and the rear cover gasket 01J301475N. All automatic transmission earned perfect: to4niak:
