SPECIFIC SAFETY INSTRUCTIONS
AND WARNINGS
WARNING: NEVER use for any purpose other than
those uses outlined above!
1. Verify that the product and application are compatible;
if in doubt, call OEMTOOLS®at 1-866-458-2472.
2. Before using this product, read the operator’s manual
completely and familiarize yourself thoroughly with
the product and its components, and recognize the
hazards associated with its use.
3. Wear appropriate safety gear (including heavy duty
work gloves and ANSI-approved safety goggles) during
use.
4. Ensure the Transmission Jack rolls freely. Raise and
lower the unloaded Transmission Jack throughout the
lifting range before putting into service to ensure the
pump operates smoothly. Replace worn or damaged
parts.
5. DO NOT exceed the weight capacity of the
Transmission Jack. Make sure weight is evenly
distributed. Be aware of dynamic loading! Sudden load
movement may briefly create excess load causing
product failure. Exceeding the maximum capacity for
this product is dangerous and can lead to serious injury
or property damage.
6. Never use this device as a work/repair station. Transfer
the load immediately to a suitable work station.
7. Always evaluate your task before using this product.
This Transmission Jack is designed to support a
transmission or a differential as individual components.
Use only as intended.
8. Assemblies such as differential with axle, or
transmission with bell housing, can be bulky and
difficult to balance. Lifting or supporting such
assemblies, even within weight limit, can create an
off-balance situation, causing the Transmission Jack
to tip over and MAY lead to serious personal injury or
property damage.
9. The load should be evenly distributed on the
Transmission Jack, and should not extend beyond the
area of the caster wheelbase. Always use the chains
provided to secure the load. If extra support is required,
safety straps (not included) can also be used to secure
the work piece.
10. Use only a hard, level and flat surface capable of
bearing the combined weight of the Transmission Jack,
the load being lifted, the operator and any tools being
used.
11. If loaded Transmission Jack must be moved, make
certain that the load is secured by appropriate means,
is stable, is in the lowest possible position, is moved
over a smooth, hard level surface, and that the lifting
platform is level.
12. If you are working and the load becomes off-balance
and/or the Transmission Jack begins to tip over,
WARNING: DO NOT ATTEMPT TO CATCH OR LIFT
THE LOAD WHEN FALLING. SERIOUS PERSONAL
INJURY CAN RESULT! In this event, clear the area as
quickly and safely as possible in order to avoid injury from
the falling load, including getting hit with flying fragments.
13. Before each use, inspect the general condition of the
Transmission Jack. Check for oil leaks, Transmission
Jack operation, loose components, free rotation
and pivoting of saddle adjustment components. If a
problem occurs, have the problem corrected before
further use.
ASSEMBLY
1. Connect Bases (#43) to the pump frame by using a Flat
Washer (#48), Lock Washer (#49) and Bolt (#50).
2. Attach 2 pieces of Locking Castors (#47) and 2 Wheels
(#52) to the base by using Nut (#44), Flat Washer (#45)
and Lock Washer (#46).
3. Install the Saddle (#04) onto the Transmission Jack and
tighten the bolt on the saddle to secure the saddle.
WARNING: TO PREVENT SERIOUS INJURY: DO
NOT USE A DAMAGED OR MALFUNCTIONING JACK.

OPERATION
Please bleed the Transmission Jack according to
the bleeding instructions before you start using the
Transmission Jack.
1. Follow the instructions for removal and installation of
transmission, transfer case or transaxle according to
the vehicle manufacturer’s service manual.
2. Prior to initial use, jack up the saddle and, using
the release valve, attempt to lower it. This will help
you become familiar with the control functions and
Transmission Jack.
3. Once the vehicle is safely and properly secured,
position the Transmission Jack underneath the vehicle.
4. Raise the Transmission Jack by operating the foot
pump until the saddle reaches the component. After
making contact with the transmission, make sure it is
centered within the brackets on the saddle plate. Use
adjustment knobs to position the saddle base.
5. Lift the Transmission Jack slightly to transfer the weight
of the transmission from the vehicle chassis to the
Transmission Jack. Secure the chain assembly around
the component.
6. Remove transmission fasteners, freeing it from the
vehicle. Make sure there is nothing to restrict the
movement of the transmission.
7. Back transmission away to free from engine.
8. Check the saddle, making sure it is securely holding
and aligned with the transmission and not showing any
signs of stress. Carefully lower transmission and saddle
by depressing the release valve. Always lower the
saddle slowly.
9. Once the transmission has been disconnected from
the engine, very slowly operate the release pedal.
Make sure the Transmission Jack’s saddle and
transmission do not hang up on any under vehicle
components, wiring, fuel lines, etc. Continue to lower
the Transmission Jack all the way down.
10. After removal, lower the Transmission Jack to the lowest
possible point before attempting to move the jack .
WARNING:The Transmission Jack is designed to
lift loads only for short periods of time. DO NOT use to
suspend a load for more than 30 minutes at a time.
11. To re-mount the transmission, reverse this procedure.
MAINTENANCE
BLEEDING
If the jack is not able to raise the load or raises very
