CLUTCH AIR PRESSURE TESTS
Inoperative clutches can be located by substituting air
pressure for fluid pressure. The clutches may be
tested by applying air pressure to their respective pas-
sages after the valve body has been removed. Use
Plate Set 6599-1 (1) and 6599-2 (1) to perform test.
To make air pressure tests, proceed as follows:
NOTE: The compressed air supply must be free of
all dirt and moisture. Use a pressure of 30 psi.
1. Remove oil pan and valve body. (Refer to 21 -
TRANSMISSION/AUTOMATIC - 42RLE/VALVE
BODY - REMOVAL)
2. Apply air pressure to the holes in the plates (1),
one at a time.
3. Listen for the clutch to apply. It will give a slight
thud sound. If a large amount of air is heard escap-
ing, the transmission must be removed from vehi-
cle, disassembled and all seals inspected.
2/4 CLUTCH
Apply air pressure to the feed hole located on the 2/4 clutch retainer (2). Look in the area where the 2/4 piston
contacts the first separator plate and watch carefully for the 2/4 piston tomoverearward.Thepistonshouldreturn
to its original position after the air pressure is removed.

OVERDRIVE CLUTCH
Apply air pressure to the overdrive clutch apply passage and watch for the push/pull piston to move forward. The
piston should return to its starting position when the air pressure is removed.
REVERSE CLUTCH
Apply air pressure to the reverse clutch apply passage and watch for the push/pull piston to move rearward. The
piston should return to its starting position when the air pressure is removed.
LOW/REVERSE CLUTCH
Apply air pressure to the low/reverse clutch feed hole passage. Look in thearea where the low/reverse piston con-
tacts the first separator plate. Watch carefully for the piston to move forward. The piston should return to its original
position after the air pressure is removed.
UNDERDRIVE CLUTCH
Because this clutch piston cannot be seen, its opera-
tion is checked by function. Use an air nozzle (2) to
apply air pressure is to the low/reverse or the 2/4
clutch opening in Test Plate 6599-1 (2). This locks the
output shaft. Use a piece of rubber hose wrapped
around the input shaft and a pair of clamp-on pliers to
turn the input shaft. Next apply air pressure to the
underdrive clutch. The input shaft should not rotate
with hand torque. Release the air pressure and con-
firm that the input shaft will rotate.
FLUID LEAKAGE
FLUID LEAKAGE - TORQUE CONVERTER HOUSING AREA
When diagnosing converter housing (5) fluid leaks,
three actions must be taken before repair:
1. Verify proper transmission fluid level.
2. Verify that the leak originates from the converter
housing area and is transmission fluid.
3. Determine the true source of the leak.
Fluid leakage at or around the torque converter area
may originate from an engine oil leak (7). The area
should be examined closely. Factory fill fluid is red
and, therefore, can be distinguished from engine oil.
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 (1) leaks tend to move along the drive hub and onto the rear of the converter. Pump o-ring or pump
body leaks follow the same path as a seal leak. Pump attaching bolt (3) leaksare generally deposited on the inside
of the converter housing (5) and not on the converter itself. Pump seal (1) or gasket (4) leaks usually travel down
the inside of the converter housing.

TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
Torque converter weld leaks at the outside diam-
eter weld (1).
Torque converter hub weld (2).
STANDARD PROCEDURE - ALUMINUM THREAD REPAIR
DamagedorwornthreadsinthealuminumtransmissioncaseandvalvebodycanberepairedbytheuseofHeli-
Coils
, or equivalent. This repair consists of drilling out the worn-out damagedthreads. Then tap the hole with a
special Heli-Coil
tap, or equivalent, and installing a Heli-Coilinsert, or equivalent, into the hole. This brings the
hole back to its original thread size.
Heli-Coil
, or equivalent, tools, and inserts are readily available from most automotive parts suppliers.
REMOVAL
1. Disconnect the negative battery cable.
2. Raise and support the vehicle
3. Remove any necessary skid plates. (Refer to 13 -
FRAMES & BUMPERS/FRAME/TRANSFER CASE
SKID PLATE - REMOVAL)
4. Mark propeller shaft and axle companion flanges
for assembly alignment.
5. Remove the rear propeller shaft. (Refer to 3 - DIF-
FERENTIAL & DRIVELINE/PROPELLER SHAFT/
PROPELLER SHAFT - REMOVAL)
6. Remove the front propeller shaft, if necessary.
(Refer to 3 - DIFFERENTIAL & DRIVELINE/PRO-
PELLER SHAFT/PROPELLER SHAFT -
REMOVAL)
7. Disconnect the input (1) and output (2) speed sen-
sors.
8. Disconnect the transfer case shift motor and mode
sensor assembly (3).
9. Disconnect the variable line pressure connector (4)
from the transmission, if equipped.
10. Disconnect the transmission range sensor (5).

NOTE: One of the oil pan bolts has a sealing patch
applied from the factory. Separate this bolt for
reuse.
14. Remove the transmission oil pan bolts (2).
15. Removethetransmissionoilpan(1).
16. Remove the transmission oil filter screws (2).

17. Remove transmission oil filter (1).
18. Remove the oil filter o-ring (2) from the valve
body.
19. Remove valve body-to-case bolts (1).

26. Remove and discard the oil pump-to-case bolts
(1). The oil pump bolts are not to be reused.
27. Remove oil pump using Slide Hammers C-3752
(2).
28. Remove oil pump while pushing in on input shaft
(1).

29. Remove oil pump gasket (2).
CAUTION: By-pass valve must be replaced if a
transmission failure has occured.
30. Remove the cooler by-pass valve (1).
31. Remove the #1 caged needle bearing (1).

42. Remove the oil pump o-ring (2) and install oil
pump and gasket to transmission.Use screw-in
dowels or phillips-headscrewdrivers to align
pump to case. Be sure to reinstall O-ring on
oil pump after selecting the proper No. 4
thrust plate.
43. Measure the input shaft end play with the trans-
mission in the vertical position. This will ensure
that the measurement will be accurate.
44. Set up and measure endplay using End Play Set
8266 (1, 2) and Dial Indicator Set C-3339 (3) as
shown.
45. Measure input shaft end play.Input shaft end
play must be 0.127 to 0.635 mm (0.005 to 0.025
inch).For example, if end play reading is 0.055
inch, select No. 4 Thrust Plate which is 0.071 to
0.074 thick. This should provide an input shaft
end play reading of 0.020 inch, which is within
specifications.
46. Remove oil pump, gasket, and input clutch
assembly to gain access to and install proper #4
thrust plate.
47. Install input clutch assembly (1) with proper thrust
plate.
