INTRODUCTION
• A badly worn or damaged transmission is removed
from the vehicle for repair, and there are essentially
four repair choices:
–
–
–
–
Repair or replace the worn/damaged component,
Overhaul the transmission
Replace the transmission with an exchange/used
Install a remanufactured transmission.
• When the overhaul is done by a technician working
at an automotive repair facility, it will be guaranteed
by the shop.

TRANSMISSION DISASSEMBLY
• The disassembly procedure
for a transmission varies
between makes and
models.
• Special tooling or
procedures are often
required.

TRANSMISSION DISASSEMBLY
• Predisassembly Cleanup
– Cleanliness is a must during
a transmission overhaul.
– Many shops steam clean or
pressure wash the outside of
the transmission as soon as it
is removed from the vehicle.
FIGURE 16-5 This transmission is being cleaned using
a hot, highpressure washer. A thorough cleaning makes
it easier to locate and remove bolts and retaining rings
and keeps the work area cleaner.

TRANSMISSION DISASSEMBLY
• Torque Converter Removal
– The converter is removed from the vehicle with the
transmission.
– It is then removed from the transmission by sliding it out
the front of the transmission.
• Disassembly Fixtures
– During disassembly, the transmission is placed on the
bench and torn down.
– It is usually placed upside down and rolled over as
needed.

TECH TIP
• Some shops use a simple fixture that resembles a
threelegged stool; other shops simply use an old
transmission case in a rear-side-up position.
FIGURE 16-7 This simple, shop-made stool (a) has a hole for the
transmission output shaft (b). The output shaft of this
transmission being repaired has been placed through the rear
opening of an empty case (c). Caution should be exercised if
using either support method. Because of the narrow bases, they
can tip over.

PRELIMINARY DISASSEMBLY
• The first teardown step is to remove the oil pan,
filter, and valve body.
• Many technicians use the oil pan to store the
retaining rings, screws, bolts, and other small parts
removed during disassembly.
• The procedure is to remove the pan, inspect the
debris (if it has not been done already), wash the
pan in solvent, and air dry it Next, the filter and
gasket are removed and set aside for comparison
with the new filter.
• The valve body is then removed and set aside for
cleaning and inspection

• Some transmissions use
steel tubes to transfer a
fluid passage from one
location to another.
• These tubes normally use
an O-ring to seal each end
and are held in place by a
retaining bracket.

SPECIAL NOTES ON RETAINING RINGS
• A retaining ring is
commonly used to hold a
part in place.
• It can hold a gear in
position on a shaft or a
servo cover in a bore.
FIGURE 16-14 The most common styles of retaining
rings are external, pin type (a), internal pin type (b),
plain external (c), plain internal (d), and E-clip (e).

• End-Play Check
– It is standard practice to
measure the input shaft end
play before removing the
pump.
– End play is the in-and-out
movement of the shaft.
– To measure input shaft end
play, you should do the
following:
FIGURE 16-16 Input shaft end play is an important
check for internal wear in a transmission. Note that a
more accurate check is made if the input shaft is
vertical. (Courtesy of Chrysler Corporation)

TECH TIP
• The measuring stylus must
be parallel to the input
shaft.
• The indicator body should
be adjusted to load the
stylus about one full needle
rotation
FIGURE 16-19 A dial indicator should be set up with the
indicator stem parallel to the input shaft and the stem is
loaded about one revolution of the indicator dial (1).
Next, move the input shaft completely into the
transmission (2),and rotate the dial to zero the needle
(3).When the input shaft is lifted, the amount of end
play can be read on the indicator dial.

PUMP REMOVAL
• The pump assembly is the front cover that holds the
gear train inside the case on RWD transmissions.
• Its removal allows the disassembly of the rest of the
internal parts.
• The pump is held in place by a set of bolts.
• The close fit between the outer pump diameter and
the case plus a rubber sealing ring and/or gasket
makes pump removal a little difficult.
• Several methods can be used to remove the pump.
– These include slide hammers, special screw-type pullers,
and prying on the gear train.

checked to make sure it
freewheels in one direction
and locks in the other.

• A one-way roller clutch also
can be assembled
improperly.
• The accordion spring
should preload the rollers in
the lockup direction, and, if
possible, place the spring
so it will tend to move away
from freewheeling race
FIGURE 16-50 The accordian spring in some one-way
clutches can be installed in a direction so that it will rub
against the inner race. This can cause wear and
breaking of the spring.

TECH TIP
• A center support with a
clutch piston must have a
fluid passage between it
and the case.
• This passage is often
sealed with a special seal
that is installed after the
center support is installed.
FIGURE 16-51 After this center support (640) with the
rear gear assembly (651) is installed (a), it must be
positioned properly using tool J23093 before the
retaining bolt (25) is installed (b). On some
transmissions, a tube seal should be installed as shown
to prevent fluid leaks in the center support and its
clutch. (Reprinted with permission of General Motors)

• You can determine if a
clutch is completely
installed by measuring its
position in the transmission
case

FIGURE 16-57 An H-shaped gauge is being used to
check end play (a). It is adjusted to fit the transmission
(left) and then moved to check the clearance at the
pump (right). A shop-made gauge can be used in the
same manner; note the use of an old band to support
the gauge at the pump.

• Torque Converter
Installation
– The converter must align at
three points: turbine spline,
stator spline, and pump.
– Most converters use two flats
or notches that engage the
pump drive gear, and these
notches should be positioned
to align with the pump drive
gear before installation
FIGURE 16-60 A torque converter must fully
engage the pump, stator support, and turbine shaft
(circles).

TECH TIP
• If a torque converter depth
dimension is not available,
pump tang engagement
can be checked by noting
how deep the converter is
in the housing, rotating the
converter a turn or so, lifting
the converter back out, and
noting if the pump drive
tangs are aligned with the
location of the converter
hub.
FIGURE 16-62 The torque converter was rotated and
then removed. The pump drive lug (circle) must align
with the position of the converter drive tang.

SUMMARY
1. Automatic transmissions are removed from a vehicle for
overhaul, repair, or replacement.
2. A transmission overhaul includes inspection of all reusable
parts, a check of the clearances, and replacement of all
gaskets, seals, friction materials, the filter, and worn
bushings.
3. Remanufactured transmissions have been overhauled and
updated in a factory-like environment.
4. Transmission parts are classified as hard or soft parts.
Hard parts are not commonly replaced. Soft parts are
commonly replaced during an overhaul.
5. Although the overhaul procedures for various transmissions
are similar, there are differences, and service information
should always be consulted when overhauling or servicing
an automatic transmission.
