Pressure drain adapter for Mercedes Benz and BMW automatic transmissions.

Gravity drain will leave a significant amount of old fluid, and this kit will allow for the use of air pressure to properly drain the remainder of the fluid when servicing the transmission.


  1. Drain the transmission as normal and remove the sump.
  2. Select and fit the correct adapter for the transmission, and connect the air release valve.
  3. Connect the air pressure hose and increase air pressure to 0.5 kg/cm2 (7 psi), and slowly open the air release valve.
  4. Dispose of the contaminated transmission fluid.
