DODGE RAM SRT-10 2006 Service Repair Manual

11. Remove accumulator outer spring (2) (diesel
engines only), piston (1), and inner spring (3)
(V-10 engine only). Note position of piston and
springs for assembly reference. Remove and dis-
card piston seals if worn or cut.
12. Remove pump oil seal with suitable pry tool or
slide-hammer mounted screw.
13. Remove front band lever pin access plug (1). Use
square end of 1/4 in. drive extension (2) to
remove plug as shown.
14. Begin removal of the oil pump and reaction shaft
support assembly by tightening the front band
adjusting screw (2) until band is tight around front
clutch retainer. This will prevent retainer from
coming out with pump and possibly damaging
clutch or pump components.

15. Remove oil pump bolts.
16. Thread Slide Hammers C-3752 (2) into threaded
holes in flange of oil pump housing (1).
17. Remove oil pump and reaction shaft (1) support
by bumping slide hammers outward alternately to
pull pump from case.
18. Remove oil pump gasket (1). Note gasket position
in case for assembly reference.

19. Loosen front band adjusting screw until band is
completely loose.
20. Remove front band strut (2) and anchor (3).
21. Squeeze front band (1) together slightly and slide
band over front clutch retainer (2) and out of
case.

22. Remove front and rear clutch assemblies (1) as a
unit.
23. Remove front band reaction pin and lever (1).
Start pin through lever and out of case bore with
drift or punch. Then use pencil magnet to with-
draw pin completely (2).
24. Remove intermediate shaft thrust washer (1). Tri-
angular shaped washer will either be on shaft pilot
hub (2) or in rear clutch retainer.

25. Remove thrust plate (1) from intermediate shaft
hub (2).
26. Remove intermediate shaft-planetary geartrain
assembly (1).
27. Loosen rear band locknut and loosen adjusting
screw 3-4 turns.
28. Remove snap-ring (3) that retains low-reverse
drum (1) on overdrive piston retainer hub.

29. Slide low-reverse drum (1) and thrust washer (3)
off piston retainer hub and out of rear band.
30. Note that overrunning clutch race (1) will remain
on splines of low-reverse drum after removal.The
raceisapermanentpressfitonthehub
splines. Do not attempt to remove the race.
31. Remove overrunning clutch assembly (2). Assem-
bly can be removed without displacing rollers and
springs if care is exercised. Note position of roll-
ers and springs for assembly reference.

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.

3. Install rear servo spring (1) and retainer (3) in case
bore. Be sure spring (1) is seated on piston (2).
4.CompressrearservopistonwithC-clamp(2)or
Valve Spring Compressor C-3422-B and install
servopistonsnap-ring(4).
5. Lubricate front servo piston (2) components and
servo bore in case with transmission fluid.
6. Install front servo piston (2) in bore. Carefully “run”
small, suitable tool (1) around piston ring to press it
back into groove and ease installation. Rotate pis-
tonintoboreatsametime.Rockpistonslightlyto
ease piston ring past snap-ring groove and into
bore.

7. Bottom front servo piston in bore and install servo
spring.
8. Install front servo piston rod (2) guide as follows:
a. Place Tool SP-5560 (or similar size tool) (5) on
guide and position C-clamp on tool and case.
b. Slowly compress rod guide while simulta-
neously easing seal ring into bore with suitable
tool.
9. Install rod guide snap-ring (4).
OVERRUNNING CLUTCH, REAR BAND, AND LOW-REVERSE DRUM
1. Install overrunning clutch components if not yet
installed.
2. Position rear band reaction pin and band in case.
Be sure that the twin lugs on the band are seated
against the reaction pin.
3. Install low-reverse drum. Slide drum through rear
band, onto piston retainer hub and into engage-
ment with overrunning clutch and race.
4. Install thrust washer in low-reverse drum spotface
(2). Use petroleum jelly to hold washer in place.
5. Install snap-ring (3) that secures low-reverse drum
to piston retainer hub.
6. Insert the rear band pivot pin part way into the
case.
7. Install rear band adjusting lever and pivot pin. Be
sure lever and the single lug on the band are
aligned and engaged before seating band pivot pin in case.
PLANETARY GEARTRAIN, FRONT/REAR CLUTCH, AND FRONT BAND
1. Remove Alignment Shaft 6227-2, if installed previ-
ously.
2. Install assembled intermediate shaft and planetary
geartrain (1).Support shaft carefully during
installation. Do not allow shaft bearing/bushing
surfaces to become nicked or scratched.
