MAINTENANCE
The ATX-2 Plus will provide any years of reliable service if properly aintained. The following checklist will
ensure that the ATX-2 Plus will run at peak efficiency and present an i age to your custo ers that your shop
perfor s high tech trans ission services.
1. Use tool tray for storage of tools and adapters only.
2. Keep the exterior surface clean. Use a ild all-purpose cleaner to wipe trans ission fluid and dirt off
the cabinet.
3. Do not allow the unit to sit outside in direct sunlight or incle ent weather. Excessive exposure to
sunlight or oisture will cause serious da age and will void the warranty.
4. The ATX-2 Plus is not intended for obile use where the unit is transported to custo er sites.
Excessive vibration will shorten co ponent life, affect accuracy of perfor ance and void the warranty.
If the ATX-2 Plus needs to be transported by vehicle, re ove all fluid, in both the new and used tanks,
prior to transport.
5. Be gentle when oving the ATX-2 Plus around the shop. Tip the unit and ease the front casters over
any obstacles such as door ja s, air hoses and floor irregularities.
6. Periodically check all internal (by lifting out the tool tray) and external hoses for leaks or excessive
wear. Any weak hoses should be replaced i ediately to avoid possible injury.
7. Check the four filter screens (Ite 4 and 6 on Page 15) often to avoid any blockage that ay occur.
Clean out debris or replace the filter screen if necessary.
Calibration - A Goo Practice
The ATX-2 Plus Boost is the ost accurate of all trans ission fluid exchange
equip ent due to the advanced load cell technology designed into the unit.
Most operating proble s are usually fixed by perfor ing a si ple calibration
procedure.
A good practice is to periodically calibrate the ATX-2 Plus to ensure opti u
perfor ance.
The following pages describe the reasons for calibration and the actual calibration
procedure.
Precision calibration weight(s) are included with the ATX-2 Plus.

Page 14
ATX-2 PLUS CALIBRATION
The ATX-2 Plus is a high-tech, electronically controlled achine for exchanging trans ission fluid. The ATX-2
Plus is connected in series with the trans ission fluid flow path at the cooler hose. The vehicles trans ission
pu p along with the lower ounted diaphrag boost pu p, deposit used fluid into the ATX-2 Plus used fluid
tank. The ATX-2 Plus upper gear pu p, pushes new fluid to the trans ission fro the tank of new fluid in the
ATX-2 Plus at the sa e or very si ilar rate as it is being re oved fro the trans ission. Trans ission pu ps
vary in their flow rate fro vehicle anufacturer to anufacturer. This requires that the ATX-2 Plus onitor
the old fluid co ing fro the trans ission and then pu p new fluid back to the trans ission at the sa e
rate.
The used and new fluid tanks in the ATX-2 Plus each sit on a weight scale (load cell). The increasing weight of
used fluid is onitored by the electronic controller which in turn controls the speed of the ATX-2 Plus upper
gear pu p, which is pu ping new fluid to the trans ission.
So, the function of the ATX-2 Plus is to pu p new fluid into the trans ission as the trans ission pu ps out
used fluid at a rate that will keep the trans ission fluid level consistent. Not too uch and not too little. This
occurs with the design of the ATX-2 Plus in a near-perfect world. So, what is the real world?
Real world conditions ust be considered:
1) Not all new trans ission fluids weigh exactly the sa e. They are very close.
2) Old trans ission fluids can have different weights. Very old fluid can have a lot of solids
suspended in the fluid and be very heavy.
3) Not all trans issions pu p or control the flow of fluid in the sa e way. So e are very slow.
Others cycle the flow of fluid off and on to the cooling lines dependent on the te perature of the
fluid. To reduce the effect of the two conditions entioned above, the ATX-2 Plus contains a
boost pu p that assists the vehicles trans ission pu p in re oving fluid, ulti ately to decrease
the exchange ti e.
These real world inconsistencies are expected and therefore the add or re ove ½ Liter feature was built into
the ATX-2 Plus
Slots are provided on the sides of the ATX-2 Plus so that the technician can see the fluid levels in the tanks.
The scales next to the slots approximately indicate the nu ber of liters in the tanks. The only purpose of
these slots is to give the technician an idea of when the used fluid tank ight need to be e ptied or how
any bottles of new fluid to bring fro the supply roo to fill the new fluid tank.
Calibration of BOTH loa cells is require when:
1. REMOVE USED FLUID
FLUID FLUID
FLUID flashes and three beeps are heard when trying to select a ount of fluid to be
exchanged. The level of fluid in the used fluid tank is observed to be such that the tank is not full or
would not fill to capacity during an exchange procedure. For exa ple, 8 LITERS is pressed and there is
obviously roo in the used fluid tank to accept 10 or ore liters.
2. ADD NEW FLUID flashes and three beeps are heard when trying to select a ount of fluid to be
exchanged. For exa ple, 8 LITERS is pressed and ore than 10 liters of fluid can be seen in the new
fluid tank.
3. REMOVE USED FLUID flashes continuously.
4. ADD NEW FLUID flashes continuously.
5. The control board is replaced for any reason.
