3. Locate and disconnect the cooler line at the easiest connection point and install adapters:
a) At cooler line connection to radiator. Connection is usually accessible from the top corner of the
radiator (could be on either top side).
b) At clamped rubber hose connection to transmission cooler (connections are usually accessible from
the under side of the vehicle (cooler is usually in front of radiator).
c) At cooler line connecting to the transmission.
4. Connect the FLOW DIRECTION INDICATOR LOOP (‘H’ adapter) to the previously attached cooler line
adapters. Verify that the male to male quick disconnect is not installed in the ‘H’ adapter. NOTE: The ball
valve must be in the (CLOSED) position. (The valve handle is at a right angle to flow.) VERIFY THAT THE
‘MALE TO MALE’ NIPPLES ARE REMOVED FROM THE HYDRAULIC COUPLERS! See photo.
5. Attach the unit to the vehicle’s battery by connecting the unit’s red battery clip to the positive (+) battery
terminal and connecting the black (-) battery clip to a solid ground point as far from the battery as
possible. The ENGINE START light will be flashing. NOTE: The ENGINE START light must always be
flashing before starting engine.
6. Start the vehicle’s engine. Note the direction of flow of the dirty fluid, (slightly open the valve if necessary)
from the cooler lines (right or left side of the adapter). After determining direction of flow, rotate the valve
handle 90° (OPEN). Transmission flow is now in the closed loop (or bypass mode) and fluid is circulating
from the vehicle, through the ‘H’ adapter, and back to the vehicle.
7. Attach the units hose marked “DIRTY OIL” to the fitting of the “H” adapter that indicated flow from the
vehicle (dirty side). Attach the hose marked “CLEAN OIL” to the side of the adapter that indicated flow to
the vehicle. (Must use male to male liquid adaptor.) Once unit’s lines are connected to the “H” adapter,
(CLOSE) the “H” adapter valve handle. See photo above. The unit is now in bypass mode (fluid flowing
from the vehicle thru the TransTech unit and back to the vehicle) and is ready to begin service.
