COOLER MODE
FLUSH
1. Vehicle engine is running and the ATX-3 is connected as previously described, READY light is
illuminated.
2. Slowly add Flush Solution as recommended by the supplier into the vehicle through the
transmission system dipstick port.
3. The ATX-3 will now circulate the solution through the transmission system until a procedure is
selected. The Flush Solution will be removed from the system during the exchange procedure.
DRAIN PAN
Note: If transmission filter is to be replaced, perform the following procedure before removing
the transmission pan. If not, skip to the next procedure.
1. Vehicle engine is running and the ATX-3 is connected as previously described, READY light is
illuminated.
2. Light on COOLER MODE button should be illuminated. 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 will not proceed with the procedure, check all connections.
4. Vehicle transmission pump will empty contents of the transmission system into the ATX-3 used
fluid tank. Liquid level can be viewed through the Used Fluid Level Indicator on the left side of the
ATX-3.
5. When vehicle pan is emptied of transmission fluid the ATX-3 will automatically switch to 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 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 Quart button (refer to the +1/2 QUART
section). Check the transmission dipstick periodically while refilling to reach proper level.
Note: If the ATX will not add +1/2 quart, 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 quarts have been added to the
transmission. Restart vehicle and verify the Ready LED is illuminated. Check fluid
level in the transmission. The +1/2 Quart and -1/2 Quart procedures can be used to
adjust the level.
Caution: Do not let the engine run for more than one minute after the ATX-3 buzzer
sounds. Letting the transmission run with an empty pan for an extended amount
of time can cause serious damage to the transmission system.
