knob located on the lid of the dispensing
unit.
18
Close the fluid dispensing hose shutoff
valve, and carefully remove the adapter
from the master cylinder, being careful
not spill any brake fluid.
19
Extract excess fluid or top-off the master
cylinder as required, and replace the cap.
20
Dispose of any hydraulic fluid remaining
in the Dispenser. Do not store hydraulic
fluid in the reservoir. Clean the dispens-
ing unit with denatured alcohol and store
it properly.
21
Test the brake or clutch system for leaks
before driving the car.
The mityvac fluid dispensing system is
appropriate for use to refill or top-off sealed
automatic transmissions. Additional acces-
sories and adapters may be required and are
available from Mityvac for performing this
function.
NOTE
Do not allow the dispensing unit or
master cylinder reservoir to run dry. Use
the pressure relief valve to relieve the
pressure and add new fluid if necessary
C AUTION
Lifetime “sealed” transmissions require
the use of special manufacturer recom-
mended fluids. Use of any other fluids
may cause severe damage to the trans-
mission and void the manufacturer’s
warranty
Refilling sealed
automatic
transmissions
1
Unscrew the lid w/ pump from the reser-
voir, and fill to desired level with new vehi-
cle manufacturer’s recommended trans-
mission fluid.
2
Reinstall the lid w/ pump onto the
reservoir.
3
Connect the fluid dispensing hose to the
reservoir using the quick-connect coupler.
Ensure the coupler sleeve snaps forward
to lock the connection.
NOTE
There are two scales of volume on the
reservoir. One scale indicates the
volume when the lid w/ pump is
removed and one when the lid w/ pump
is installed. Be sure to note the
appropriate scale.
C AUTION
If fluid is added above the MAX FILL line,
the reservoir will overflow when the lid
w/ pump is installed
4
Select the appropriate ATF refill adapter
for the application and connect it to the
output of the fluid dispensing hose.
5
Insert or connect the ATF refill adapter to
the transmission.
6
While observing the pressure gauge,
operate the pump to build pressure in the
reservoir to the desired level, or until the
proper amount of fluid has been dispensed.
NOTE
The shutoff valve installed in the fluid
dispensing hose may be left open or
closed. If left open, fluid will begin to
flow as soon as the pump is operated. If
closed, pressure will build in the
reservoir as indicated on the gauge.
NOTE
Check the vehicle’s service manual to
determine the proper method to check
the transmission fluid level. Failure to
follow the manufacturer’s recom-
mended procedure could result in
under- or over-filling the transmission,
causing severe transmission damage.
The pressure relief valve is designed
to open and maintain maximum pres-
sure between 17 and 23 psi (1.2 and 1.6
bar).
Continual operation of the pump is
not required to maintain fluid flow. Fluid
will continue to flow as long as there is
pressure in the reservoir and the shutoff
valve is open.
Do not exceed 25 psi (1.7 bar) pres-
sure in the reservoir. The relief valve
should prevent this, but if it fails and the
pressure exceeds 25 psi, immediately
discontinue use and send the unit to an
authorized service center for repair or
replacement.
7
Once the proper amount of fluid has been
dispensed, close the shutoff valve on the
fluid dispensing hose and bleed off the
pressure by tilting the pressure relief knob
located on the lid.
8
Depending on the type of fluid and future
intended use, store or empty the remain-
ing fluid from the reservoir.
9
Clean the unit with denatured alcohol or
common household cleaners, and store it
properly.
