Power Steering Fluid Level - PREVOST H3-45 2023 Operator's Manual

The transmission fluid level dipstick is accessible
through the engine compartment rear door and is
located on the left side of the engine.
To check the transmission fluid level, a "cold
check" and a "hot check" must be performed. A
cold check must be made when the transmission
o
fluid is between 60 F and 120
o
50 C).
NOTE
Perform the cold check first to verify the
transmission fluid level before performing the
hot check.
To prevent dirt and foreign matter from entering
the transmission, clean the end of the oil fill tube
before removing dipstick. To remove dipstick,
unscrew filler cap approximately three turns and
pull out dipstick.

Cold Check
l
Run the engine until the transmission fluid
temperature is between 60
o
and 50 C). With the engine idling, make sure the
parking brake is applied and the transmission is
in neutral (N). Shift transmission from forward (D)
to reverse (R) and back into neutral (N) to fill
clutch cavities with fluid. Remove and wipe the
dipstick with a clean cloth. Check fluid level. If
the fluid level is within the COLD RUN band, the
fluid level is correct and a hot check can be
performed. If the fluid level is on or below the
lower line of the COLD RUN band, add fluid until
the level lies within the COLD RUN band. If the

fluid level is above the COLD RUN band, drain

CAUTION
The fluid level rises as fluid temperature rises. Do
not add fluid above the "cold run" band before the
transmission reaches 180
o

Hot Check
l
Make sure the transmission fluid temperature is
between 160ºF and 200ºF (71ºC and 93ºC)
before performing the hot check. With the engine
idling between 500 and 800 RPM and the parking
brake applied, shift transmission into neutral (N).
Remove and clean dipstick, then check fluid
level. If the fluid level is on or under the lower
HOT RUN line, add just enough fluid to bring up
the level to the middle of the HOT RUN band.

Replace dipstick and tighten the filler tube cap
until the rubber seal is correctly seated.
CAUTION
Do not overfill transmission fluid reservoir.
Severe damage may result.
