Mercedes Benz and BMW Transmission Oil Drain Tool Kit
Most of oil drain tools use gravity to drain the transmission oil out, but it is unable to drain out all the transmission oil.
This transmission oil drain tool kit is able to drain out the rest of transmission oil cleanly by air pressure to keep the transmission clean. There will be around 2.6 L oil left in the transmission of some car models if this kit is NOT used.
1. Drain out the transmission first, and remove the oil sump.
2. Assemble the transmission oil drain tool kit: Connect the air compressor with air hose, and connect the air hose with the air release valve. Connect a suitable adapter according to the transmission and then connect adapter to the air release valve.
3. Fit the adapter to the oil drain plug hole, open the air release valve, increase the air pressure to 0.5 kg/cm2, and the rest of transmission oil will be drained out.
