STANDARD PROCEDURE - ALUMINUM
THREAD REPAIR
Damaged or worn threads in the aluminum trans-
mission case and valve body can be repaired by the
use of Heli-CoilsŸ, or equivalent. This repair con-
sists of drilling out the worn-out damaged threads.
Then tap the hole with a special Heli-CoilŸ tap, or
equivalent, and installing a Heli-CoilŸ insert, or
equivalent, into the hole. This brings the hole back to
its original thread size.
Heli-CoilŸ, or equivalent, tools and inserts are
readily available from most automotive parts suppli-
ers.
REMOVAL
(1) Disconnect the negative (ground) battery cable.
CAUTION: Isolate ground lead to prevent accidental
contact.(2) Apply parking brake.
(3) Move gear selector lever to position ªNº.
(4) Remove oil drain plug (2) (Fig. 26) and drain
automatic transmission oil into a clean container.

Torque Converter Lockup Clutch Regulating Valve
The torque converter lock-up clutch regulating
valve (6) (Fig. 102) is located in the valve housing of
the electrohydraulic control module. The valve is
responsible for the hydraulic control of the torque
converter lockup clutch and distribution of the lubri-
cating oil.

Shift Pressure Shift Valve
When the multiple-disc brake B1 (3) is activated,
the working pressure (p-A) is applied to the end face
of the 1-2 / 4-5 shift pressure shift valve (4) (Fig. 117)
via the command valve (1). Its shift state is main-
tained during the shift phase by substituting the
shift element pressure acting on its end face (and
which is variable during the shift phase) with a cor-
responding constant pressure. When the multi-plate
clutch K1 (2) is activated, the end face of the shift
valve is unpressurized during the stationary and
shift phases, so the shift state is maintained during
the shift phase in this case too.Lubrication Pressure Regulating Valve
At the working pressure regulating valve surplus
oil is diverted to the lubrication pressure regulating
valve (1) (Fig. 118), from where the lubrication pres-
sure (p-Sm) is used in regulated amounts to supply
the transmission lubrication system including the
torque converter.

upper and lower side of the crescent (1) to the pres-
sure chamber (6) of the housing. The meshing of the
teeth prevents oil flowing from the delivery side to
the intake side. An external gear (3) is eccentrically
mounted in the pump housing. The external gear is
driven by the internal gear (4) which is connected to
the torque converter hub.
DISASSEMBLY
(1) Remove pump gears (1 and 2) (Fig. 186) from
pump housing.
(2) Remove the inner oil pump seal (1) (Fig. 187).
(3) Replace the outer oil pump O-ring (2) (Fig.
187).
INSPECTION
Before measuring any oil pump components, per-
form a thorough visual inspection of all the compo-nents. If any sign of scoring, scratches, or other
damage is seen, replace the oil pump as an assembly.
SIDE CLEARANCE
Side clearance is the difference between the thick-
ness of the pump gears and the depth of the pocket
in the pump housing. Side clearance can be mea-
sured by laying a flat plate across the mounting face
of the pump housing, and measuring the distance
between the plate and the gears.
Acceptable side clearance:
²Inner gear: 0.064 mm (0.0025 in) max
²Outer gear: 0.069 mm (0.0027 in) max
TIP CLEARANCE
Tip clearance is the difference between the tip
diameters of the gear teeth and the corresponding
diameters of the pocket in the pump housing.
Tip clearance for the inner gear can be checked by
moving the inner gear into tight mesh (2) (Fig. 188)
with the outer gear as shown. Clearance between the
ID of the crescent feature of the housing and the OD
of the teeth of the inner gear (3) should then me
measured at a point 37 mm from the corner of the
crescent (1) feature, as shown below.
Acceptable tip clearance for inner gear:
²0.85 mm (0.033 in) max

directly, which means that the solenoids must have
very high outputs to close the valves against the siz-
able flow areas and line pressures found in current
transmissions. Fast response time is also necessary
to ensure accurate control of the transmission.
The strength of the magnetic field is the primary
force that determines the speed of operation in a par-
ticular solenoid design. A stronger magnetic field will
cause the plunger to move at a greater speed than a
weaker one. There are basically two ways to increase
the force of the magnetic field:
1. Increase the amount of current applied to the
coil or
2. Increase the number of turns of wire in the coil.
The most common practice is to increase the num-
ber of turns by using thin wire that can completely
fill the available space within the solenoid housing.
The strength of the spring and the length of the
plunger also contribute to the response speed possi-
ble by a particular solenoid design.
A solenoid can also be described by the method by
which it is controlled. Some of the possibilities
include variable force, pulse-width modulated, con-
stant ON, or duty cycle. The variable force and pulse-
width modulated versions utilize similar methods to
control the current flow through the solenoid to posi-
tion the solenoid plunger at a desired position some-
where between full ON and full OFF. The constant
ON and duty cycled versions control the voltage
across the solenoid to allow either full flow or no flow
through the solenoid's valve.UPSHIFT / DOWNSHIFT SOLENOID VALVES
The solenoid valves (1) for upshifts and downshifts
(Fig. 229) are located in the shell of the electric con-
trol unit and pressed against the shift plate with a
spring.
The solenoid valves (1) initiate the upshift and
downshift procedures in the shift plate.
The solenoid valves (1) are sealed off from the
valve housing of the shift plate (5) by two O-rings (4,
6). The contact springs (8) at the solenoid valve
engage in a slot in the conductor tracks (7). The force
of the contact spring (8) ensures safe contacts.
