Para 3-4/3-7
(4)
Check the oil level on the dipstick at least
twice.
It should register at the Full mark each time.
Inconsistency in registration may be due to pressure
buildup in the transmission.
Improper venting to
atmosphere of the breather (para 3-9) may be a frequent
cause of this problem.
CAUTION
The oil level rises as sump temperature
increases.
Therefore, do not fill above
the Add mark before the transmission
has
reached
normal
operating
temperature.
e. Safe Level.
The safe operating level is from the
Add mark to the Full mark on the dipstick.
Do not
operate the vehicle when the oil level is higher or lower
than the Full-Add range.
3-4.
KEEP OIL CLEAN
Oil must be handled in clean containers, fillers, etc,
to prevent foreign material entering the transmission.
CAUTION
Containers or fillers that have been used
for any antifreeze solution must not be
used for oil that is to be used in the
transmission.
Clean around oil filler tube before removing dipstick, and
lay dipstick in a c 1 e a n place while filling the
transmission.
Check the current issue of the HT 700
Series Parts Catalog (SA 1268) for proper replacement
oil filter.
Keep filters in cartons until ready for installation.

OIL SPECIFICATIONS
a.
Dexron® is the only fluid recommended for the
HT 700D series transmission.
Type C2 and Type A
fluids may be used to fill the transmission or intermixed
with Dexron, but only in an emergency, when Dexron is
not available.
b. Ambient Temperatures.
When the ambient
temperature is below -300F (-340C), an auxiliary preheat
is required.
Raise the sump temperature to above -300F
(-340C) before operating the transmission.
3-6.
OIL AND OIL FILTER CHANGE INTERVALS
Oil and oil filter change frequency is determined by
the transmission application and by the filter equipment
installed.
The following table is a general guide.
More
frequent changes may be required when operations are
subject to high levels of contamination.
3-7.
OIL AND OIL FILTER CHANGE PROCEDURES
a. The transmission should be at operating
temperature (160-2000F) (71-930C) when the oil is
drained.
This will insure quicker and better drainage.
b. On earlier models, remove the fill tube from the
oil pan and allow the oil to drain.
On later models
remove the drain plug from the rear of the oil pan and
allow the oil to drain.
Check the condition of the oil as
described in paragraph 3-8.
