we found a green o-ring as first equipment in 0AW and 0B5 transmissions. But the manufacturer offers a black o-ring of different dimensions for repair. The green o-ring would be our part-no. A-ORG-120262, the black one A-ORG-119671 - both o-rings are included in this sub-kit. Please choose carefully which one to use - we are not sure if the dimensions make a difference or the black o-ring replaces the green one - there are no info available from the manufacturer.
