*Isometric Exchange: Ensure the exchange volume of new ATF and old ATF is equal. *Isobaric Exchange: During the operation the pressure inside the system will keep the same. It is especially useful for CVT design vehicles. *Auto Re-router Installed: Mechanics don't need to distinguish the ATF flow direction before performing the service. Simply connect the ATF cooling line to AT-2000 and the device will direct the flow in a proper way. *Auxiliary Exchange: For low ATF pressure vehicles, mechanics may activate this function to help sucking out the old ATF. It helps to save time and increase exchange efficiency. *Auto By Pass: During Exchange, when AT-1000 empty new ATF it will switch automatically to circulation mode to ensure the safety of vehicle. *Complete Fitting Set: With this fitting set AT-2000 can work on most vehicles available in the market.
