CONNECTING TO THE TRANSMISSION SYSTEM
3. Select and install proper fitting adapters to disconnect points. Use closest matching adapter and
o-ring to seal any leaks if exact matching adapter can not be found. In some cases it may be
easier to use one of the open end rubber hose adapters on the disconnected male fitting on the
cooler line then to select the matching adapter.
4. Connect 12 inch adapter hoses to fitting adapters.
5. Connect 10 ft black and red hoses (right side of ATX-3) to the 12 inch adapter hoses.
6. Connect red (positive) clamp on power cable to red (positive) terminal on vehicle battery. Connect
the black (negative) clamp to a ground on vehicle frame. All lights on keypad should illuminate for
one second and buzzer should pulse. If not, check connections and make sure REVERSE
POLARITY light is not illuminated.
WARNING: Handle battery connection cable with extreme caution. Batteries generate
explosive gases during normal operation. Working in the vicinity of a lead-acid or
other automotive battery is dangerous. Wear eye protection. Never smoke or allow
a spark or flame in the vicinity of the battery. Do not connect the black power clip
to the negative post of the battery to avoid a spark.
7. Set the park brake and turn engine on, listen for the buzzer to sound once loudly and for the
READY light on the keypad to stay illuminated. The ATX-3 pressure gauge on the control panel
will indicate a positive pressure if the connection to the transmission is correct.
If buzzer does not sound and light does not illuminate IMMEDIATELY TURN ENGINE OFF and
switch the black and red 10 ft hoses and repeat the above.
Note: For most Chrysler and Mitsubishi vehicles the transmission pump will be functioning when
the vehicle is in “Neutral” instead of “Park”. Perform the service in Neutral gear on these
vehicles.
8. Press the COOLER MODE button. The light on the button will illuminate.
9. Once the ATX-3 is connected properly (READY light stays illuminated) the machine automatically
goes into circulate mode. Check hoses for heat, if circulate is working correctly both hoses should
be warm to the touch.
10. The ATX-3 pressure gauge will indicate the transmission operating pressure. Refer to the
manufacturer’s recommended pressure to determine if the transmission system is functioning
correctly.
