OPERATION MANUAL

ATX-3

Automatic Transmission Fluid Exchanger

WARNING

DO NOT pour anything except new

transmission fluid into the fill port.
Serious damage will result.

The ATX-3 must be connected to a
FULLY CHARGED 12 volt battery. This
should be the battery in the vehicle being
serviced.

Do not use a battery charger to power
the ATX-3.

Use of undercharged batteries and
battery chargers will damage the ATX-3
and void the warranty.

Calibration - A Good Practice

The ATX-3 is the most accurate of all transmission fluid exchange equipment due to the
advanced load cell technology designed into the unit.

Most operating problems are usually fixed by performing a simple calibration procedure.

A good practice is to periodically calibrate the ATX-3 to ensure optimum performance.

Precision calibration weight(s) are included with the ATX-3.

Safety Precautions

WARNING: Failure to follow these precautions can result in serious

injury or death.

• Read and understand the Operation Manual completely before operating this unit.

• Always wear proper eye and skin protection when operating and maintaining this equipment.

• Take precautions to keep clothing, hair, hands, hoses etc. away from all moving parts of the vehicle.

• Many Automatic Transmission systems can be extremely hot and operate at high pressures. Always

use extreme caution when connecting and dis-connecting hoses and adapters.

• Always keep a fire extinguishing device nearby when working with flammable liquids.

• Choose a well ventilated work area and avoid breathing any harmful fumes when performing a
transmission fluid exchange.

• Check engine oil level and coolant level. Refill if low. Do not perform the exchange if either is low.

• Flush solutions are combustible and are harmful or fatal if swallowed. If swallowed call doctor
immediately and do not induce vomiting. If Flush Solution gets in eyes flush with water immediately.
For contact with skin wash with soap and water. Apply skin lotion if necessary to sooth irritation.

• Immediately clean up any transmission fluid spills and use proper container for disposal.

• Comply with local, state, and federal regulations for fluid disposal.

• Material Safety Data Sheets (MSDS) must be obtained on all chemicals and placed in a shop file
for reference.

IMPORTANT

Check transmission fluid level according to manufacturer’s

instructions before connecting the ATX-3

Adjust fluid level if required

KEYPAD FUNCTIONS

The ATX-3 is an automatic transmission fluid exchanger featuring state-of-the-art electronic controls
with digital weight scales measuring the automatic transmission fluid coming into and going out of the
machine. Operation of the ATX-3 is intuitive and very easy to master.

560-80414-00

Transmission fluid is removed from vehicle and filtered before collecting in the ATX-3
used fluid tank. When the procedure is complete, the ATX-3 buzzer will sound
continuously until the stop button is pressed. Refer to page 8 for cooler mode and
page 12 for dipstick mode for complete instructions.

Filters and exchanges the used transmission fluid in the vehicle for new from the ATX-

3. The procedure is complete when the buzzer sounds continuously until the stop
button is pressed. Refer to page 9 for cooler mode and page 12 for dipstick mode for
complete instructions.

Transmission fluid is emptied completely from the new fluid tank inside the ATX-3. It
can be stored in a bulk container for later use. This procedure is performed if a
change in transmission fluid types is required. The ATX-3 buzzer will sound
continuously until the stop button is pushed when procedure is complete. Refer to
page 14 for complete instructions.

Transmission fluid is emptied completely from the used fluid tank inside the ATX-3
into a bulk used tank for proper disposal. This procedure is performed when the used
fluid tank is full or the used fluid tank capacity is not sufficient to perform selected
exchange. The ATX-3 buzzer will sound continuously until the stop button is pushed
when procedure is complete. Refer to page 14 for complete instructions.

KEYPAD FUNCTIONS

Used after the exchange process if fluid level is too high on the transmission dipstick.
Removes ½ quart of fluid from the transmission. The ATX-3 buzzer will sound
continuously until the stop button is pushed when procedure is complete. Refer to
page 9 for cooler mode and page 13 for dipstick mode for complete instructions.

Used after the exchange process if fluid level is too low on the transmission dipstick.
Adds ½ quart of transmission fluid to the transmission from the ATX-3 new fluid tank.
The ATX-3 buzzer will sound continuously until the stop button is pushed when
procedure is complete. Refer to page 9 for cooler mode and page 13 for dipstick
mode for complete instructions.

Stops any procedure the moment it is pushed, also used at the end of a procedure to
acknowledge completion of process and turn buzzer off.

Illuminates when battery connection is backwards.

Illuminates when the used tank is too full or flashes when the capacity remaining is
less than exchange amount selected. The EMPTY Used procedure must be run to
continue operation of the ATX-3.

Illuminates when the new fluid tank is empty or flashes when the new fluid level is less
than the selected exchange amount. The operator must add fluid to the new fluid tank
of the ATX-3 through the fill port.

Illuminates when the vehicle engine is running and connected properly to the ATX-3.

Illuminates when the selected process is complete. The buzzer will sound
continuously when this is illuminated.

The ATX-3 provides two modes of fluid exchange - Cooler or dipstick mode. The
mode is selected using these buttons when the ATX-3 is powered up. During dipstick
mode, the start engine button is pressed at a specified step.

Two LED readouts display the amount of fluid in the New and Used fluid tanks and
give realtime readouts as the different procedures run.

Caution: Always use fingers to operate keypad. Use of sharp objects will cause damage

and void the warranty.

1. Add desired amount of transmission fluid to the new fluid tank through the ATX-3 fill port. Monitor

fluid level in the ATX-3 with the LED readouts or with fluid sight indicators.

2. Locate and disconnect the transmission cooler lines at the most convenient location:

A. At cooler line connecting to radiator usually most accessible if vehicle is not on lift.

B. At clamped rubber hose connection to transmission cooler usually most accessible if vehicle

is on a lift. Cooler is most often in front of the radiator.

C. At cooler line connecting to the transmission usually requires vehicle to be on a lift.
