Oil pan and overflow tube modified - BT27.10-P-0006-01W

TRANSMISSION 722.901 

To improve fluid supply to the transmission, the transmission oil pan and the overflow tube have been redesigned.

The characteristic sloped surface (arrow) can be used to identify the new oil pan (1). This oil pan configuration should be installed only together with the white overflow tube (2).

The fluid temperatures used as references for checking and refilling are different with the new components.

Whenever a transmission is removed for repairs, the earlier oil pan (3) with the black overflow tube (4) should be replaced by the new sloped-surface version (1) with the white overflow tube (2).
