SOLENOID SWITCH VALVE
The solenoid switch valvecontrols line pressure from
the LR/CC solenoid (4). Inone position, it allows the
low/reverse clutch to be pressurized. In the other, it
directs line pressure to the converter control and con-
verter clutch valves (7).

MANUAL VALVE
The manual valve (4) is operated by the mechanical
shift linkage. Its primary responsibility is to send line
pressure to the appropriate hydraulic circuits and sole-
noids. The valve has three operating ranges or
positions.
CONVERTER CLUTCH SWITCH VALVE
The main responsibility of the converter clutch switch
valve (10) is to control hydraulic pressure applied to
the front (off) side of the converter clutch piston. Line
pressure from the regulator valve (5) is fed to the
torque converter regulator valve (8). The pressure is
then directed to the converter clutch switch valve (10)
and to the front side of the converter clutch piston.
This pressure pushes the piston back and disengages
the converter clutch.

CONVERTER CLUTCH CONTROL VALVE
The converter clutch control valve (5) controls the
back (on) side of the torque converter clutch (1).
When the controller energizes or modulates the
LR/CC solenoid to apply the converter clutch piston,
both the converter clutch control valve (5) and the
converter control valve move, allowing pressure to be
applied to the back side of the clutch.
T/C REGULATOR VALVE
The torque converter regulator valve slightly regulates the flow of fluidto the torque converter.
LOW/REVERSE SWITCH VALVE
The low/reverse clutch is applied from different sources, depending on whether low (1st) gear or reverse is selected.
The low/reverse switch valve alternates positions depending on from which direction fluid pressure is applied. By
design, when the valve is shifted by fluid pressure from one channel, the opposing channel is blocked. The switch
valve alienates the possibility of a sticking ball check, thus providing consistent application of the low/reverse clutch
under these operating conditions.
REMOVAL
NOTE: If valve body is being reconditioned or replaced, it is necessary to perform the Quick Learn Proce-
dure. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSIONCONTROL MODULE -
STANDARD PROCEDURE)

1. Disconnect the transmission range sensor (5) and
solenoid/pressure switchassembly wiring connec-
tors.
2. Disconnect the variable line pressure connector (4),
if equipped.
3. Disconnect the shift cable from the shift lever (at
the transmission).
4. Move the manual shift lever clockwise as far as it
will go. This should be one position past the L posi-
tion. Then remove the manual shift lever.
NOTE: One of the oil pan bolts has a sealing patch
applied from the factory. Separate this bolts for
reuse.
5. Remove transmission pan bolts (2).
6. Remove transmission oil pan (1).

7. Remove oil filter (1) from valve body. It is held in
place by two screws.
8. Remove valve body bolts-to-case (1).
CAUTION: The overdrive and underdrive accumu-
lators and springs may fall out when removing the
valve body.
9. Carefully remove valve body assembly (1) from the
transmission.
DISASSEMBLY
NOTE: If the valve body is being reconditioned or replaced, it is necessaryto perform the Quick Learn Pro-
cedure using the scan tool (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION
CONTROL MODULE - STANDARD PROCEDURE)

1. Remove the electrical connectors from the pres-
sure control solenoid (1) and the line pressure sen-
sor (2).
2. Remove the screws (6) holding the pressure con-
trol solenoid (1) and line pressure sensor (2) to the
valve body.
3. Remove the pressure control solenoid and line
pressure sensor from the valve body.
4. Remove the shoulder screw (3) holding the vari-
able line pressure header (4) to the valve body.
5. Remove the variable line pressure header from the
manual shaft (5).
6. Remove manual shaft seal.
7. Remove manual shaft screw (1).

8. Remove Transmission Range Sensor (TRS) (1)
and manual shaft (2).
9. Remove Solenoid/Pressure Switch Assembly (1)
from valve body.
10. Remove valve body stiffener plate (1).

11. Invert valve body assembly and remove transfer
plate-to-valve body screws (1).
12. Remove transfer/separator plate (1) from valve
body (2)
13. Remove separator plate-to-transfer plate screws
(2).

14. Remove separator plate (1) from transfer plate
(2).
15. Remove the oil screen (1)from the transfer plate.
16. Remove thermal valve (1) from transfer plate.

17. Remove valve body check balls (1-4). Note their location for assembly ease.
18. Remove 2/4 accumulator assembly (1-5).
