 The oil pan (3) and overflow pipe (31) have been redesigned to optimize the oil supply to the automatic transmission. The previous oil pan (3) without bias and with black overflow pipe (31) is, after removal, to be replaced by an oil pan (3) with bias and with white overflow pipe (31).



Clean

3

Thoroughly clean oil pan (3) and area surrounding it.


Absolute cleanliness must be ensured when performing all work on the transmission.
Otherwise, even the smallest of foreign particles in the hydraulic components of the transmission can lead to malfunctions or a total failure of the transmission.

 For cleaning, use lint-free cleaning cloth. Chamois leathers are the most suitable.

4

Remove heat shield.
