COOLER MODE FLUID EXCHANGE (4,8,12,16,20 LITERS)
1.
Vehicle engine is running and the ATX-3 PLUS BOOST is connected as previously described, READY
light is illuminated.
2. Determine vehicle transmission fluid capacity from the vehicle operator or service manual.
3. Light on COOLER MODE button should be illuminated. Press the corresponding LITER button; always
round up (for example if vehicle capacity is 6.5 LITER, an 8 LITER exchange would be selected).
4. The exchange of fluid can be monitored through ATX-3 PLUS BOOST Old-New Sight Bowls. These
bowls display the new bright red fluid leaving ATX-3 PLUS BOOST and the dirty brown to black fluid
coming from vehicle transmission system. The color of the used should become almost equal to the new
as exchange ends. The liquid levels can be viewed through Level Indicators on either side of ATX-3 PLUS
BOOST (left side for used, right side for new).
5. When exchange of transmission fluid is complete, ATX-3 PLUS BOOST will automatically switch to the
bypass loop, the buzzer will sound continuously and PROCESS COMPLETE light will stay illuminated
until STOP button is pressed.
6. Check transmission dip stick for level. Use +1/2, -1/2 LITER buttons as required to correct fluid level
.
Servicing Vehicles with Transmission Thermostats
Common for Ford vehicles
With the vehicle engine running, the READY light will illuminate but the service will not proceed if the
transmission fluid is cold.
The fluid inside the transmission must be heated to approximately 180
̊
°
F. The most efficient way to do
this is to put the vehicle in reverse. Setting the emergency brake, using a pedal depressor, or putting
blocks behind the rear wheels can be done to help secure the vehicle. MAHLE recommends that the
vehicle is not left unattended while in gear.
The service may start with very little or no flow. The service will commence, and take approximately 15
minutes to complete.
NOTE
Some transmission pumps may have a flow rate so low that the ATX will briefly pause (or even
stop) during the exchange process. A series of two long beeps will indicate this condition.
Accelerating the engine will usually overcome this situation and decrease the overall time
required for the exchange process.
