Optional Procedure - Drain Pan for Filter Change
Warning: It is not necessary to empty the waste tank before beginning an exchange. If beginning an
exchange with fluid in the waste tank ensure that there is less fluid in the clean tank than the remaining
capacity of the waste tank. Failure to do so will result in waste tank overflowing!
1. Make sure the TransTech IV new fluid tank is filled with the correct type and amount of transmission fluid.
2. Connect TransTech IV power leads to the vehicle’s battery.
3. With vehicle running, pressure should be present at the TransTech IV pressure gauge and the START
ENGINE light should be on solid. If pressure drops to zero, and START ENGINE light is flashing, the
hoses may be reversed.
4. With the TransTech connected and engine running, press DRAIN. When the transmission pan is
emptied, ATF pressure in the machine drops, a buzzer will sound. The LOW VEHICLE FLUID and
STOP ENGINE lights will flash.
5. Immediately turn off the vehicle’s engine and press STOP to silence the alarm. Perform drain pan
service.
6. When the filter change is complete, press START/RESUME button and the TransTech IV will refill the
vehicle with the same amount of fluid removed.
7. The buzzer will sound and START ENGINE light will flash.
8. Start vehicle.
9. Press START/RESUME button to begin the exchange.
10. When fluid exchange is finished, the COMPLETE light will come on and TransTech will beep continuously
until STOP button is pressed.
11. Once transmission service is complete, check ATF level with engine running or as per manufacturer’s
recommendation. Press and hold DRAIN or FILL to adjust ATF level. Stop the engine, the service is
complete.
12. Direct waste hose to a suitable container; open the ball valve on the end of the waste hose and press
EMPTY WASTE button to empty dirty fluid tank.
Pause Feature
If service needs to be paused at any time press STOP. To resume, press START/RESUME. The machine
will pause indefinitely until the START/RESUME button is pressed. While paused, fluid will flow through the
machine in a bypass loop.
Adding ATF to Clean Tank
It is recommended that the desired amount of clean ATF to be exchanged is added to the Clean Tank before
a service begins. However, additional ATF can be added after a service has started but ONLY when the
service is paused. Any ATF added while the unit is performing a service will not be properly measured and
may result in an OVER FILL of the vehicle’s transmission!
