Cooler Mode | Connecting to the Transmission System | 7
Important
Attempt to pull hoses apart to ensure couplers are attached properly.
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 300 PLUS BOOST) 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 1 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 300 PLUS BOOST 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 function 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 300 PLUS BOOST 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 300 PLUS BOOST pressure gauge will indicate the transmission operating pressure. Refer to the
manufacturer’s recommended pressure to determine if the transmission system is functioning correctly.
