Robert Bosch LLC ATX 300 Plus Boost Operation Manual | Version 1 | September 2011
Cooler Mode | Fluid Exchange | 9
Caution
Do not let the engine run for more than one minute after the ATX 300 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.
Fluid Exchange (4, 8, 12, 16, 20 Quarts) — Cooler Mode
1. Vehicle engine is running and the ATX 300 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 QUART button, always round up
(for example if vehicle capacity is 6.5 quarts, an 8 quart exchange would be selected).
4. The exchange of fluid can be monitored through the ATX 300 PLUS BOOST Old-New Sight Bowls. These bowls
display the new bright red fluid leaving the ATX 300 PLUS BOOST and the dirty brown to black fluid coming from
the vehicle transmission system. The color of the used should become almost equal to the new as the exchange
ends. The liquid levels can be viewed through the Level Indicators on either side of the ATX 300 PLUS BOOST (left
side for used, right side for new).
5. When the exchange of transmission fluid is complete, the ATX 300 PLUS BOOST will automatically switch to the
bypass loop, the buzzer will sound continuously, and the PROCESS COMPLETE light will stay illuminated until the
STOP button is pressed.
6. Check transmission dipstick for level. Use +1/2, -1/2 QUART buttons as required to correct fluid level.
-1/2 Quart
1. Vehicle engine is running and the ATX 300 PLUS BOOST is connected as previously described, READY light
is illuminated.
2. Check transmission dipstick. Light on COOLER MODE button should be illuminated. Press the - 1/2 QUART
button to lower the fluid level if the transmission system is overfilled.
3. When process is complete the buzzer will sound continuously and the PROCESS COMPLETE light will stay
illuminated until the STOP button is pressed.
4. Check transmission dipstick for appropriate level.
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.
