AIR CHECKING TRANSMISSION CLUTCH OPERATION
Air-pressure testing can be used to check transmis-
sion clutch operation. The test can be conducted with
the transmission either in the vehicle or on the work
bench, as a final check.
Air-pressure testing requires that the oil pan and valve
body be removed from the transmission. The clutch
apply passages are shown in the Air Pressure Test
Passages graphic.
NOTE: The air supply which is used must be free
ofmoistureanddirt.Useapressureof30psito
test clutch operation.
Apply air pressure at each port. If the clutch is func-
tioning, a soft thump will be heard as the clutch is
applied. The clutch application can also be felt by
touching the appropriate element while applying air
pressure. As the air pressure is released, the clutch
should also release.
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.
1 - LOW REVERSE CLUTCH
2 - 4TH CLUTCH
3 - 2ND CLUTCH
4-OVERDRIVECLUTCH
5 - UNDERDRIVE CLUTCH
6 - REVERSE CLUTCH

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 trans-
mission for repair. Torque converter seal leaks tend to move along the drive hub and onto the rear of the converter.
Pump cover seal leaks tend to run down the cover and the inside surface of thebellhousing.
Some leaks, or suspected leaks, may be particularly difficult to locate. If necessary, a Mopar
approved dye should
be used to locate and confirm a leak.
TORQUE CONVERTER LEAK POINTS
Possible sources of converter leaks are:
1. Leaks at the weld joint around the outside diameter
weld.
2. Leaks at the converter hub weld.
In most cases, a torque converter which is wet from
transmission fluid indicates a leak at one of these
areas.
STANDARD PROCEDURE - ALUMINUM THREAD REPAIR
DamagedorwornthreadsinthealuminumtransmissioncaseandvalvebodycanberepairedbytheuseofHeli-
Coils™, or equivalent. This repair consists of drilling out the worn-out damaged threads. Then tap the hole with a
special Heli-Coil™ tap, or equivalent, and installing a Heli-Coil™ insert, 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

49. Remove the dipstick tube seal.
CLEANING
The use of crocus cloth is permissible where necessary, providing it is usedcarefully.Whenusedonshafts,or
valves, use extreme care to avoid rounding off sharp edges. Sharp edges arevital as they prevent foreign matter
from getting between the valve and valve bore.
Do not reuse oil seals, gaskets, seal rings, or O-rings during overhaul. Replace these parts as a matter of course.
Also do not reuse snap rings or E-clips that are bent or distorted. Replace these parts as well.
Lubricate transmission parts with Mopar
ATF +4, Automatic Transmission Fluid, during overhaul and assembly. Use
petroleum jelly, Mopar
Door Ease, or Ru-Glyde to prelubricate seals, O-rings, and thrust washers. Petroleum jelly
canalsobeusedtoholdpartsinplaceduringreassembly.
Clean the case in a solvent tank. Flush the case bores and fluid passages thoroughly with solvent. Dry the case and
all fluid passages with compressed air. Be sure all solvent is removed fromthe case and that all fluid passages are
clear.

NOTE: Do not use shop towels or rags to dry the case (or any other transmission component) unless they
aremadefromlint-freematerials.Lintwillsticktocasesurfacesandtransmission components and circu-
late throughout the transmission after assembly. A sufficient quantity of lint can block fluid passages and
interfere with valve body operation.
INSPECTION
Inspect the case for cracks, porous spots, worn bores, or damaged threads.Damaged threads can be repaired with
Helicoil
thread inserts. However, the case will have to be replaced if it exhibits any type of damage or wear.
ASSEMBLY
NOTE: Clean and inspect all components. Replace any components which showevidence of excessive wear
or scoring.
1. Install the cooler filter bypass valve. Torque the
bypass valve to specification. The valve uses a
tapered pipe thread and excessive torque can
damage the transmission case. Tighten the cooler
filter bypass valve to 4.5 Nꞏm (40 in.lbs.).
2. Install a new selector shaft seal (1) using Seal
Installer 8253 (2).
3. Install the manual selector shaft and retaining
screw. Tighten the manual selector shaft retaining
screw to 28 Nꞏm (250 in.lbs.).
4. Install the manual shift lever (1) onto the manual
selector shaft. Torque the retaining cross-bolt to 16
Nꞏm (140 in.lbs.).

NOTE: Before final assembly of transmission cen-
terline, the 2C/4C clutch components should be
installed into position and measured as follows:
9. Install the 2C reaction plate (4) into the transmis-
sion case.
10. Install the 2C clutch pack (2, 3) into the transmis-
sion case.
11. Install the flat 2C clutchsnap-ring(1)intothe
transmission case.
12. Install the 4C retainer/bulkhead (2) into the trans-
mission case. Make sure that the oil feed holes
are pointing toward the valve body area.
13. Install the 4C retainer/bulkhead tapered snap-ring
(1) into the transmission case. Make sure that the
open ends of the snap-ring are located in the
case opening toward the valve body area.
14. Using a feeler gauge through the opening in the
rear of the transmission case, measure the 2C
clutch pack clearance between the 2C reaction
plate and the transmission case at four different
points. The average of these measurements is the
2C clutch pack clearance. The correct clutch
clearance is 0.455-1.335 mm (0.018-0.053 in.).
The reaction plate is not selective. If the clutch
pack clearance is not within specification, the
reaction plate, all the friction discs, and steels
must be replaced.
15. Remove the 4C retainer/bulkhead and all of the
2C clutch components from the transmission case.
16. Install the low/reverse clutch assembly (1). Make
sure that the oil feed hole points toward the valve
body area and that the bleed orifice is aligned
with the notch in the rear of the transmission
case.
17. Install the snap-ring (2) to hold the low/reverse
clutch retainer into the transmission case. The
snap-ring is tapered and must be installed with
the tapered side forward. Once installed, verify
that the snap-ring is fully seated in the snap-ring
groove.
18. Air check the low/reverse clutch and verify correct
overrunning clutch operation.

27. Install the flat 2C clutch snap-ring into the transmission case.
28. Install the reaction sun gear (4) into the reaction planetary gear set.Make surethe small shoulder is facing the
front of the transmission.
29. Install the number 7 thrust bearing (5) onto the reaction sun gear (4) with the inner race against the sun gear.
30. Install the output shaft selective thrust plate (2)
onto the reaction annulus with the oil grooves fac-
ing the annulus gear and the lugs (1) and notches
aligned as shown.
