INSPECTION
Inspect the front clutch components. Replace the
clutch discs if warped, worn, scored, burned or
charred, the lugs are damaged, or if the facing is
flaking off. Replace the steel plates and reaction
plate if heavily scored, warped, or broken. Be sure
the driving lugs on the discs and plate are also in
good condition. The lugs must not be bent, cracked or
damaged in any way.
Replace the piston springs and spring retainer if
either are distorted, warped or broken.
Check the lug grooves in the clutch piston retainer.
The steel plates should slide freely in the slots.
Replace the piston retainer if the grooves are worn or
damaged. Also check action of the check ball in the
piston retainer. The ball must move freely and not
stick.
Replace the retainer bushing if worn, scored, or
there is any doubt about bushing condition.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
Check the clutch piston check ball. The ball should
be securely in place. Replace the piston if the ball is
missing, or seized in place.
ASSEMBLY
NOTE: The 46RE transmission uses three plates
and discs for the front clutch.
(1) Mount Bushing Installer SP-5511 on tool han-
dle (Fig. 97).
(2) Slide new bushing onto installer tool and start
bushing into retainer.
(3) Tap new bushing into place until installer tool
bottoms against clutch retainer.
(4) Remove installer tools and clean retainer thor-
oughly.
(5) Soak clutch discs in transmission fluid.
(6) Install new inner piston seal onto the outer
diameter of the clutch retainer inner hub.
(7) Install new outer seal onto the clutch piston.
Be sure seal lips of both seals face the interior of the
retainer.
(8) Lubricate new inner and outer piston seals
with Ru-GlydeŸ, or MopartDoor Ease.
(9) Install clutch piston in retainer. Use twisting
motion to seat piston in bottom of retainer. A thin
strip of plastic (about 0.015 - 0.020 in. thick), can be
used to guide seals into place if necessary.

DODGE RAM 2001 Service Repair Manual CAUTION: Never push the clutch piston straight in.
This will fold the seals over causing leakage and
clutch slip. In addition, never use any type of metal
tool to help ease the piston seals into place

DODGE RAM 2001 Service Repair Manual OPERATION
The application of the piston is accomplished by

ton. The pressure acts against the larger lower land
to push the piston downward, allowin

OIL PUMP BUSHING REMOVAL
(1) Position pump housing on clean, smooth sur-
face with gear cavity facing down.
(2) Remove bushing with Tool Handle C-4171 and
Bushing Remover SP-3550 (Fig. 109).
REACTION SHAFT SUPPORT BUSHING REMOVAL
(1) Assemble Cup Tool SP-3633, Nut SP-1191 and
Bushing Remover SP-5301 (Fig. 110).
(2) Hold cup tool firmly against reaction shaft.
Thread remover tool into bushing as far as possible
by hand.
(3) Using wrench, thread remover tool an addi-
tional 3-4 turns into bushing to firmly engage tool.
(4) Tighten tool hex nut against cup tool to pull
bushing from shaft. Clean all chips from shaft and
support after bushing removal.
CLEANING
Clean pump and support components with solvent
and dry them with compressed air.
INSPECTION
Check condition of the seal rings and thrust
washer on the reaction shaft support. The seal ringsdo not need to be replaced unless cracked, broken, or
severely worn.
Inspect the pump and support components. Replace
the pump or support if the seal ring grooves or
machined surfaces are worn, scored, pitted, or dam-
aged. Replace the pump gears if pitted, worn
chipped, or damaged.
Inspect the pump bushing. Then check the reaction
shaft support bushing. Replace either bushing only if
heavily worn, scored or damaged. It is not necessary
to replace the bushings unless they are actually dam-
aged.
Clearance between outer gear and reaction shaft
housing should be 0.010 to 0.063 mm (0.0004 to
0.0025 in.). Clearance between inner gear and reac-
tion shaft housing should be 0.010 to 0.063 mm
(0.0004 to 0.0025 in.). Both clearances can be mea-
sured at the same time by installing the gears in the
pump body and measure pump component clearances
as follows:
(1) Position an appropriate piece of PlastigageŸ
across both gears.
(2) Align the plastigage to a flat area on the reac-
tion shaft housing.
(3) Install the reaction shaft to the pump housing.
