Operation
2. Attach the Chain (#1A) to one
of the tabs under the Upper Plate
(Assembly Drawing on page 7) by threading
a bolt through both tabs and securing
with a nut. Note: Secure it using the last
link on one side of the chain. The linkyou
use to secure the other side will be dependent
on the size of the individual transmission
you secure to the unit.
Note: There are tabs on both sides of the Upper Plate.
The second set is for securing the Chain (#1A) after
the transmission is in place.
Lowering a transmission onto theTransmission Jack.
Note: Every time you use the Transmission Jack, see that the unit is filled with hydraulic oil.
See step 2 on page 6.
1. Once the vehicle is secured and raised on a hoist, clear the area underneath the vehicle of
people and tools.
2. Wheel the Transmission Jack under the transmission.
3. Allow the Chain (#1A) to hang to the floor still attached to one end of the Upper Plate.
4. To raise the unit, close the ReleaseValve (#29) on the Power Unit (See Assembly Drawing
on page 9). Pump the Handle (#5A) to raise the Transmission Jack. Stop just below the
transmission and level the Upper Plate with the adjusting knobs (See FIGURE 1). Turning
Knob A clockwise will tilt the Upper Plate up, raising the left side. Counterclockwise will bring
it back to level. Turning Knob B clockwise will tilt the back of the Upper Plate up, and turning
it counterclockwise will return it to a level position.

Operation (continued)
5. Continue raising the Upper Plate up to the transmission to determine where you will need
to adjust the Fingers (#2A). All four Fingers (#2A) need to grip and make contact with the
transmission.
6. After determining where they need to be set, loosen the threaded bolts on each
Finger (#2A), and adjust it to the proper setting for the transmission. Tighten the bolts.
Note: If you need to lower theTransmission Jack to make adjustments, make sure nobody is
close to the unit, and slowly turn and release the ReleaseValve (#29) until the Upper Plate is
lowered to the desired height. Then, close the ReleaseValve (#29) to stop movement. Make
your adjustments, tighten the Release Valve (#29) and raise the unit. See FIGURE 2.
7. Raise the unit again to make contact with the transmission, making sure all of the Fingers
(#2A) are in firm contact.
8. Wrap the Chain (#1) securely around the transmission and bolt the Chain (#1) to the tab
on the other side of the Upper Plate as described on page 4 (under Assembling Chain).
9. Once you are sure it is securely fastened, release the bolts holding the transmission in
place.
10. Make sure the area is clear of people and tools, and verify that the transmission is
securely held in place. Then, slowly turn and release the Release Valve (#29) to lower the
Transmission Jack.
11. Wheel the Transmission Jack from under the vehicle and perform your desired
maintenance.
Raising the Transmission Jack back into place.
1. Move the Transmission Jack so that the transmission is lined up properly with its
connection points.
2. To raise the unit, close the ReleaseValve (#29) on the Power Unit (See Assembly Drawing
on page 9). Pump the Handle (#5A) to raise the Transmission Jack. Guide it into place and
replace the hardware, securing it to the chassis. Double check it is securely installed.
