5. Line pressure should be 54-60 psi (372-414 kPa) with throttle lever forward and gradually increase to 90-96 psi
(621-662 kPa) as lever is moved rearward.
Test Three - Transmission In D Range Third Gear
This test checks pressure regulation and condition of the clutch circuits. Both test gauges are required for this test.
1. Turn OD switch off.
2. Leave vehicle on hoist and leave Oil Pressure Gauge C-3292 in place at accumulator port.
3. Move Oil Pressure Gauge C-3293-SP over to front servo port for this test.
4. Have helper start and run engine at 1600 rpm for this test.
5. Move transmission shift lever two detents rearward from full forward position. This is D range.
6. Read pressures on both gauges as transmission throttle lever is gradually moved from full forward to full rear-
ward position:
Line pressure at accumulator in D range third gear, should be 54-60 psi (372-414 kPa) with throttle lever for-
ward and increase as lever is moved rearward.
Front servo pressure in D range third gear, should be within 3 psi (21 kPa) ofline pressure up to kickdown
point.
Test Four - Transmission In Reverse
This test checks pump output, pressure regulation and the front clutch andrear servo circuits. Use 300 psi Oil
Pressure Gauge C-3293-SP for this test.
1. Leave vehicle on hoist and leave Oil Pressure Gauge C-3292 in place at accumulator port.
2. Move 300 psi Oil Pressure Gauge C-3293-SP back to rear servo port.
3. Have helper start and run engine at 1600 rpm for test.
4. Move transmission shift lever four detents rearward from full forward position. This is Reverse range.
5. Move transmission throttle lever fully forward then fully rearward andnote reading at Gauge C-3293-SP.
6. Pressure should be 145 - 175 psi (1000-1207 kPa) with throttle lever forward and increase to 230 - 280 psi
(1586-1931 kPa) as lever is gradually moved rearward.
Test Five - Governor Pressure
This test checks governor operation by measuring governor pressure response to changes in vehicle speed. It is
usually not necessary to check governor operation unless shift speeds areincorrect or if the transmission will not
downshift. The test should be performed on the road or on a hoist that will allow the rear wheels to rotate freely.
1. Move 100 psi Oil Pressure Gauge C-3292 to governor pressure port.
2. Move transmission shift lever two detents rearward from full forward position. This is D range.
3. Have helper start and run engine at curb idle speed. Then firmly apply service brakes so wheels will not rotate.
4. Note governor pressure:
Governor pressure should be no more than 20.6 kPa (3 psi) at curb idle speed and wheels not rotating.
If pressure exceeds 20.6 kPa (3 psi), a fault exists in governor pressure control system.
5. Release brakes, slowly increase engine speed, and observe speedometerand pressure test gauge (do not
exceed 30 mph on speedometer). Governor pressure should increase in proportion to vehicle speed. Or approx-
imately 6.89 kPa (1 psi) for every 1 mph.
6. Governor pressure rise should be smooth and drop back to no more than 20.6kPa (3 psi), after engine returns
to curb idle and brakes are applied to prevent wheels from rotating.
7. Compare results of pressure test with analysis chart.
Test Six - Transmission In Overdrive Fourth Gear
This test checks line pressure at the overdrive clutch in fourth gear range. Use 300 psi Oil Pressure Gauge
C-3293-SP for this test. The test should be performed on the road or on a chassis dyno.
1. Remove tachometer; it is not needed for this test.
2. Move 300 psi Oil Pressure Gauge to overdrive clutch pressure test port. Then remove other gauge and reinstall
test port plug.

3. Lower vehicle.
4. Turn OD switch on.
5. Secure test gauge so it can be viewed from drivers seat.
6. Start engine and shift into D range.
7. Increase vehicle speed gradually until 3-4 shift occurs and note gauge pressure.
8. Pressure should be 524-565 kPa (76-82 psi) with closed throttle and increase to 690-896 kPa (100-130 psi) at
1/2to3/4throttle.Notethatpressurecanincreasetoaround965kPa(140psi) at full throttle.
9. Return to shop or move vehicle off chassis dyno.

AIR TESTING TRANSMISSION CLUTCH AND BAND OPERATION
Air-pressure testing can be used to check transmis-
sion front/rear clutch and band operation. The test can
be conducted with the transmission either in the vehi-
cle or on the work bench, as a final check, after over-
haul.
Air-pressure testing requires that the oil pan and valve
body be removed from the transmission. The servo
and clutch apply passages are shown.

Front Clutch Air Test
Place one or two fingers on the clutch housing and apply air pressure through front clutch apply passage. Piston
movement can be felt and a soft thump heard as the clutch applies.
Rear Clutch Air Test
Place one or two fingers on the clutch housing and apply air pressure through rear clutch apply passage. Piston
movement can be felt and a soft thump heard as the clutch applies.
Front Servo Air Test
Apply air pressure to the front servo apply passage. The servo rod should extend and cause the band to tighten
around the drum. Spring pressure should release the servo when air pressure is removed.
Rear Servo Air Test
Apply air pressure to the rear servo apply passage. The servo rod should extend and cause the band to tighten
around the drum. Spring pressure should release the servo when air pressure is removed.
CONVERTER HOUSING FLUID LEAK
When diagnosing converter housing fluid leaks, two
items must be established before repair.
1. Verify that a leak condition actually exists.
2. Determined the true source of the leak.
Some suspected converter housing fluid leaks may
not be leaks at all. They may only be the result of
residual fluid in the converter housing, or excess fluid
spilled during factory fill or fill after repair. Converter
housing leaks have several potential sources. Through
careful observation, a leak source can be identified
before removing the transmission for repair. Pump
seal leaks tend to move along the drive hub and onto
the rear of the converter. Pump body leaks follow the
same path as a seal leak. Pump vent or pump attach-
ing bolt leaks are generally deposited on the inside of
the converter housing and not on the converter itself.
Pump o-ring or gasket leaks usually travel down the
inside of the converter housing. Front band lever pin
plug leaks are generally deposited on the housing and
not on the converter.
TORQUE CONVERTER LEAK POINTS
Possible sources of converter leaks are:
Leaks at the weld joint around the outside diameter weld.
Leaks at the converter hub weld.
CONVERTER HOUSING AREA LEAK CORRECTION
1. Remove converter.
2. Tighten front band adjusting screw until band is tight around front clutch retainer. This prevents front/rear clutches
from coming out when oil pump is removed.
3. Remove oil pump and remove pump seal. Inspect pump housing drainback andvent holes for obstructions. Clear
holes with solvent and wire.
4. Inspect pump bushing and converter hub. If bushing is scored, replace it. If converter hub is scored, either polish
it with crocus cloth or replace converter.

7 - REAR MAIN SEAL LEAK

5. Install new pump seal, O-ring, and gasket. Replace oil pump if cracked, porous or damaged in any way. Be sure
to loosen the front band before installing the oil pump, damage to the oil pump seal may occur if the band is still
tightened to the frontclutch retainer.
6. Loosen kickdown lever pin access plug three turns. Apply Loctite™ 592, orPermatex
No. 2 to plug threads and
tightenplugto17Nꞏm(150in.lbs.)torque.
7. Adjust front band.
8. Lubricate pump seal and converter hub with transmission fluid or petroleum jelly and install converter.
9. Install transmission and converter housing dust shield.
10. Lower vehicle.
DIAGNOSIS CHARTS
The diagnosis charts provide additional reference when diagnosing a transmission fault. The charts provide general
information on a variety of transmission, overdrive unit and converter clutch fault conditions.
The hydraulic flow charts in the Schematics and Diagrams section of this group, outline fluid flow and hydraulic
circuitry. Circuit operation is provided for PARK, NEUTRAL, FIRST, SECOND, THIRD, FOURTH, MANUAL FIRST,
MANUAL SECOND, and REVERSE gear ranges. Normal working pressures are alsosupplied for each of the gear
ranges.
