2006 DODGE RAM SRT-10 manual transmission

The valves contained within the valve body (1) include the following :
Regulator valve (8)
Solenoid switch valve (7)
Manual valve (5)
Converter clutch switch valve (6)
Converter clutch control valve (4)
Torque converter regulator valve (2)
Low/Reverse switch valve (3)
In addition, the valve body also contains the thermal valve, #2, 3, 4 & 5 check balls and the 2/4 accumulator assem-
bly.
OPERATION
NOTE: (Refer to 21 - TRANSMISSION/AUTOMATIC - 42RLE - SCHEMATICS AND DIAGRAMS) for a visual aid
in determining valve location, operation and design.

THERMAL VALVE
The thermal valve (1) is a bi-metallic shudder valve
that helps control the venting rate of oil pressure in
the underdrive clutch passage during release of the
clutch. When the oil temperature is approximately 20
degrees Fahrenheit or less, the valve is fully open to
assist in venting oil past the U1 orifice (2). At temper-
atures above 20 degrees, the valve starts to close and
becomes fully closed at approximately 140 degrees.
The thermal valve is located in the transfer plate of
the valve body.
REGULATOR VALVE
The regulator valve (9) controls hydraulic pressure in
the transmission. It receives unregulated pressure
from the pump (6), which works against spring tension
(8) to maintain oil at specific pressures. A system of
sleeves and ports allows the regulator valve to work at
one of three predetermined pressure levels. Regulated
oil pressure is also referred to as “line pressure.”

10 - TORQUE CONVERTER CONTROL VALVE

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 -

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).

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).

14. Install the solenoid/pressure switch assembly (1)
and screws to the transfer plate and torque to 5.5
Nꞏm (50 in. lbs.).
15. Install the manual shaft/rooster comb (3) and
transmission range sensor (1) to the valve body.
16. Install the TRS/manual shaft retaining screw (1)
andtorqueto5Nꞏm(45in.lbs.).
17. Install manual shaft seal.

18. Install the variable line pressure header onto the
manual shaft (5).
19. Install the shoulder screw (3) to hold the variable
line pressure header (4) to the valve body.
20. Install the pressure control solenoid and line pres-
sure sensor into the valve body.
21. Install the screws (6) to hold the pressure control
solenoid (1) and line pressure sensor (2) to the
valve body.
22. Install the electrical connectors to the pressure
control solenoid (1) and the line pressure sensor
(2).
INSTALLATION
1. Install valve body into position and start bolts (1).
Torque valve body to transmission case bolts (1) to
12 Nꞏm (105 in. lbs.) torque.
2. Install transmission oil filter (1).
