Theory of Operations
Detailed descriptions of the various operations, control buttons, and indicators that make up the control panel are
listed below.
OFF MODE:
• When the unit is connected to power, an alarm will sound indicating power-up. Fluid will be
re-circulated to the vehicle’s transmission.
• When the vehicle is started, the unit will sound an alarm indicting that fluid and pressure from the vehicle
have reached the machine and it is ready for service.
CHANGE FLUID:
If pressed before draining the transmission pan (at beginning of service), the unit will automatically rout the
used fluid from the vehicle’s transmission into the unit’s WASTE tank, and supply an equal amount of new fluid
from the unit’s CLEAN fluid tank to the vehicle.
• If pressed after the transmission fluid was drained using the DRAIN button, the machine will add to the
transmission the equal amount of fluid collected during the drain mode, plus the amount entered manually
using the FILL button (see FILL section), once this amount is added to the transmission, an alarm will sound
and the ENGINE START light will flash. At this time the technician should start the engine. Once started,
the machine will automatically rout the used fluid to the WASTE tank and supply new fluid into the
vehicle’s transmission.
Note: Fluid level in the transmission may vary during service. Level will be adjusted automatically at end
of service.
• If pressed and held while power is connected to unit, the unit’s computer will commence the PRIME
mode. This procedure is used any time the waste tank is drained completely.
DRAIN:
•
If pressed at beginning of service, fluid will be drained from the vehicle’s transmission into the machine’s
WASTE tank until no fluid is received from the vehicle’s transmission. An alarm and ENGINE STOP light
will be activated when the transmission fluid pan is empty.
• The machine’s computer will account for the amount of fluid collected in the WASTE tank during the
DRAIN mode.
• If pressed after service, (The COMPLETE light is lit), fluid will drain only as long as the button is pressed,
flow will stop when the button is released.
FILL:
•
If pressed at beginning of service, for every time pressed the unit count ½ of a quart, a light will turn ON to
indicate the amount entered (see chart in this section). The unit will automatically add the amount of fluid
indicated to the overall fluid level of the transmission.
EXAMPLE: When the technician checks the transmission’s fluid level before beginning the service, and the
