OIL PRESSURE CHECK
Road or Normal Operating Conditions
While road testing (with the transmission oil pressure
gage attached and the vacuum modulator tube
connected, the transmission pressure should check
approximately as shown on figure 3 IT.
Vehicle Stationary - Engine at 1200 RPM
With the transmission oil pressure gauge attached and
the vacuum modulator tube disconnected, the transmis
sion pressures should check approximately as shown in
Fig. 32T.
Vehicle Stationary - Engine at 1000 RPM
With the transmission oil pressure gauge attached and
the vacuum modulator tube connected for normal
modulator operation, the transmission pressure should
check approximately as shown in Fig. 33T.
NOTE: Pressures are not significantly af
fected by altitude or barometric pressure
when the vacuum modulator tube is
connected.
Case Porosity Repair
External leaks caused by case porosity have successfully
been repaired with the transmission in the vehicle by
using the following recommended procedures:
1. Road test and bring the transmission to operating
temperature, approximately 180 degrees.
2. Raise vehicle on hoist or jack stand, engine running
and locate source of oil leak. Check for leak in all
operating positions. Use of a mirror is helpful in
finding leaks.
3. Shut engine off and thoroughly clean area to be
repaired with a cleaning solvent and a brush air
dry.
4. Using instructions of the manufacturer, mix a
sufficient amount of epoxy, Part No. 1360016, or
equivalent to make repair. Observe cautions of mfg.
in handling.
5. While the transmission case is still HOT apply the
epoxy to the area to be repaired. A clean, dry
soldering acid brush can be used to clean the area
and also to apply the epoxy cement. Make certain
the are to be repaired is fully covered.
6. Allow cement to cure for three hours before starting
engine.
7. Road test and check for leaks.
VACUUM MODULATOR DIAGNOSIS
A defective vacuum modulator can be determined by
performing the following procedures.
Vacuum Diaphragm Leak Check
Insert a pipe cleaner into the vacuum connector pipe as
