12. Place a rag over the compression test tool fitting. Crank the engine for2–3 seconds to purge any fuel that may
have drained into the cylinder when the injector was removed.
13. Connect the compression test gauge.
14. Crank the engine for 5 seconds and record the pressure reading. Repeat this step three times and calculate the
average of the three readings.
NOTE: The minimum cylinder pressure is 350 psi. Cylinder pressure should be within 20% from cylinder to
cylinder.
15. Combustion pressure leakage can be checked if cylinder pressure is below the specification. Perform the leak-
age test procedure on each cylinder according to the tester manufacturer instructions.
16. Upon completion of the test check and erase any engine related fault codes.
CYLINDER COMBUSTION PRESSURE LEAKAGE
The combustion pressure leakage test provides an accurate means for determining engine condition.
Combustion pressure leakage testing will detect:
Exhaust and intake valve leaks (improper seating).
Leaks between adjacent cylinders or into water jacket.
Any causes for combustion/compression pressure loss
1. Start and operate the engine until it attains normal operating temperature.
2. Disconnect injector harness connectors.
3. Disconnect breather tube and breather drain tube from valve cover.

STANDARD PROCEDURE
STANDARD PROCEDURE - FORM-IN-PLACE GASKETS AND SEALERS
There are numerous places where form-in-place gaskets are used on the engine. Care must be taken when apply-
ing form-in-place gaskets to assure obtaining the desired results.Do not use form-in-place gasket material
unless specified.Bead size, continuity, and location are of great importance. Too thin a bead can result in leakage
while too much can result in spill-overwhich can break off and obstruct fluid feed lines. A continuous bead of the
proper width is essential to obtain a leak-free gasket.
There are numerous types of form-in-place gasket materials that are used in the engine area. Mopar
Engine RTV
GEN II, Mopar
ATF-RTV, and MoparGasket Maker gasket materials, each have different properties and can not
be used in place of the other.

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.

32. Remove rear band adjusting lever and reaction
pin.
33. Remove rear band.
34. Compress front servo rod guide (2) with large
C-clamp (1) and Tool C-4470 (4), or Compressor
Tool C-3422-B. Compress guide only enough to
permit snap-ring removal (about 1/8 in.).
35. Remove servo piston snap-ring (4). Unseat one
end of ring. Then carefully work removal tool
around back of ring until free of ring groove.Exer-
cise caution when removing snap-ring. Servo
bore can be scratched or nicked if care is not
exercised.
36. Remove tools and remove rear servo retainer (3),
spring and piston assembly.
CLEANING
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.
Lubricate transmission parts with Mopar
ATF +4, Automatic Transmission fluid, during overhaul and assembly. Use
petroleum jelly to prelubricate seals, O-rings, and thrust washers. Petroleumjellycanalsobeusedtoholdpartsin
place during reassembly.
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.
Lubricate the front band adjusting screw threads with petroleum jelly andthread the screw part-way into the case.
Be sure the screw turns freely.
Inspect the transmission bushings during overhaul. Bushing condition isimportant as worn, scored bushings con-
tribute to low pressures, clutch slipand accelerated wear of other components. However, do not replace bushings
as a matter of course. Replace bushings only when they are actually worn, orscored.

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.
ASSEMBLY
Do not allow dirt, grease, or foreign material to enter the case or transmission components during assembly. Keep
the transmission case and components clean. Also make sure the tools and workbench area used for reassembly
operations are equally clean.
Shop towels used for wiping off tools and your hands must be made fromlint freematerials. Lint will stick to trans-
mission parts and could interfere with valve operation or even restrict fluid passages.
Lubricate transmission clutch and gear components with Mopar
ATF +4 during reassembly. Soak clutch discs in
transmission fluid before installation.
Use petroleum jelly on piston seals and o-rings to ease installation. Petroleumjellycanalsobeusedtolubricate
and hold thrust washers and plates in position during assembly.
Do not use chassis grease, bearing grease, white grease, or similar lubricants on any part.These types of
lubricants can eventually block or restrict fluid passages and valve operation. Use petroleum jelly only.
Do not force parts into place. The transmission components and sub-assemblies are easily installed by hand when
properly aligned. If a part seems difficult to install, it is either misaligned or incorrectly assembled. Verify that thrust
washers, thrust plates and seal rings are correctly positioned.
The planetary geartrain, front/rear clutch assemblies and oil pump are all much easier to install when the transmis-
sion case is upright. Either tilt the case upward with wood blocks, or cut a hole in the bench large enough for the
intermediate shaft and rear support. Then lower the shaft and support intothe hole and support the rear of the case
directly on the bench.
FRONT/REAR SERVO
1. Lubricate rear servo piston seal with ATF +4. Lubri-
cateservoboreincasewithATF+4.
2. Install rear servo piston (1) in case. Position piston
at slight angle to bore and insert piston with twist-
ing motion.
