light is illuminated.
2. Press the DRAIN PAN button on the keypad.
3. Buzzer will sound once and DRAIN PAN light will stay illuminated. If an error occurs the buzzer will sound
three times and the ATX-3 PLUS BOOST will not proceed with the procedure, check all connections.

system into the ATX-3 PLUS BOOST used fluid tank. Liquid level can be viewed through the Used Fluid
Level Indicator on the left side of the ATX-3 PLUS BOOST.

the circulate mode, the buzzer will sound continuously and the PROCESS COMPLETE light will stay
illuminated until the STOP button is pressed.
6. Turn the vehicle off IMMEDIATELY after ATX-3 PLUS BOOST buzzer sounds. The vehicle is now ready to
have the transmission pan removed.
7. After the pan is replaced, refill the pan using the +1/2 Liter button (refer to the
+1/2 LITER section).
Check the transmission dip stick periodically while refilling to reach proper level.
Note: If the ATX will not add +1/2 liter, there may not be enough fluid remaining in the
transmission to satisfy the minimum pressure requirement. To correct this situation, stop
engine. Press Empty New Fluid and manually monitor the level of fluid in the new fluid
tank. Press the Stop button after two liters have been added to the transmission. Restart
vehicle and verify the Ready LED is illuminated. Check fluid level in the transmission. The
+1/2 liter and -1/2 liter procedures can be used to adjust the level.
Caution: Do not let the engine run for more than one minute after the ATX-3 PLUS BOOST
buzzer sounds. Letting the transmission run with an empty pan for an extended amount of
time can cause serious damage to the transmission system.
