Up to transmission production date "September 20, 2004", transmissions with two plugs were installed.

Following that, the second plug was discontinued and the oil is drained and the oil level is checked only with the plug -A-.

The oil level in the transmission is determined with the length of the plastic overflow tube with 8 mm socket head (tightening specification: 3 Nm).

-- Remove the overflow tube.
