2006 DODGE RAM SRT-10 oil filter

The oil pump also contains a number of valves. The
converter clutch switch (3) and control valves (2),
pressure regulator valve (5), and converter pressure
limit valve (6) are all located in the oil pump valve
body.
A front seal (2), and a bolt on reaction shaft (5) complete the oil pump assembly.

DISASSEMBLY
1. Remove the bolts holding the reaction shaft support (5) to the oil pump.
2. Remove the reaction shaft support (5) from the oil pump.
3. Remove all bolts holding the oil pump halves together.
4. Using suitable prying tools, separate the oil pump sections by inserting the tools in the supplied areas and prying
the halves apart.
NOTE: The oil pump halves are aligned to each other through the use of two dowels. Be sure to pry upward
evenly to prevent damage to the oil pump components.

6. Position the oil pump valve body (6) onto the locating dowels.
7. Seat the two oil pump halves together and install all bolts finger tight.
8. Torque all bolts down slowly starting in the center and working outward.The correct torque is 4.5 Nꞏm (40
in.lbs.).
9. Verify that the oil pump gears rotate freely and smoothly.
10. Position the reaction shaft support (5) onto the oil pump valve body (6).
11. Install and torque the bolts to hold the reaction shaft support (5) to the oil pump valve body (6). The correct
torque is 12 Nꞏm (105 in.lbs.).

LOW/REVERSE SWITCH VALVE
The low/reverse switch valve allows the low/reverse clutch to be operatedby either the LR/CC solenoid or the MS
solenoid.
REMOVAL
NOTE: The valve body can be removed for service without having to remove thetransmission assembly.
The valve body can be disassembled for cleaning and inspection of the individual components. (Refer to 21
- TRANSMISSION/AUTOMATIC - 45RFE/VALVE BODY - DISASSEMBLY)
1. Shift transmission into PARK.
2. Raise vehicle.
3. Disconnect wires at the solenoid and pressure
switch assembly connector.
4. Position drain pan under transmission oil pan.
5. Remove transmission oil pan.
6. Remove the primary oil filter (1) from valve body.
7. Remove bolts (1) attaching valve body to transmis-
sion case.
8. Lower the valve body and work the electrical con-
nector out of transmission case.
9. Separate the valve body from the transmission.

INSTALLATION
1. Check condition of seals on valve body and the
solenoid and pressure switch assembly. Replace
seals if cut or worn.
2. Place TRS selector plate in the PARK position.
3. Place the transmission in the PARK position.
4. Lubricate seal on the solenoid and pressure switch
assembly connector with petroleum jelly.
5. Position valve body in transmission and align the
manual lever on the valve body to the pin on the
transmission manual shift lever.
6. Seat valve body in case and install one or two
bolts to hold valve body in place.
7. Tighten valve body bolts alternately and evenly to
12 Nꞏm (105 in. lbs.) torque.
CAUTION: The primary oil filter seal MUST be fully
installed flush against the oil pump body. DO NOT
install the seal onto the filter neck and attempt to
install the filter and seal as an assembly. Damage
to the transmission will result.
8. Install a new primary oil filter seal in the oil pump
inlet bore. Seat the seal in the bore with the butt
end of a hammer, or other suitable tool.
9. Place replacement filter (1) in position on valve
body and into the oil pump.
10. Install screw to hold filter to valve body. Tighten
screw to 4.5 Nꞏm (40 in. lbs.) torque.
11. Connect the solenoid and pressure switch assem-
bly connector.
12. Install oil pan. Tighten pan bolts to 12 Nꞏm (105 in. lbs.) torque.
13. Lower vehicle and fill transmission with Mopar
AT F + 4 .
14. Check and adjust gearshift cable, if necessary.

3. Lower vehicle.
4. Turn OD switch on.
5. Secure test gauge so it can be viewed from drivers seat.
6. Start engine and shift into D range.
7. Increase vehicle speed gradually until 3-4 shift occurs and note gauge pressure.
8. Pressure should be 524-565 kPa (76-82 psi) with closed throttle and increase to 690-896 kPa (100-130 psi) at
1/2to3/4throttle.Notethatpressurecanincreasetoaround965kPa(140psi) at full throttle.
9. Return to shop or move vehicle off chassis dyno.

AIR TESTING TRANSMISSION CLUTCH AND BAND OPERATION
Air-pressure testing can be used to check transmis-
sion front/rear clutch and band operation. The test can
be conducted with the transmission either in the vehi-
cle or on the work bench, as a final check, after over-
haul.
Air-pressure testing requires that the oil pan and valve
body be removed from the transmission. The servo
and clutch apply passages are shown.

Loose/Misadjusted.2. Repair or replace linkage components.
3. Rear Clutch Burnt. 3. Removeand disassemble transmission
and rear clutch and seals. Repair/replace
worn or damaged parts as needed.
4. Valve Body Malfunction. 4. Remove and disassemble valve body.
Replace assembly if any valves or bores
are damaged.
5. Transmission Overrunning Clutch
Broken.5. Remove and disassemble transmission.
Replace overrunning clutch.
6. Input Shaft Seal Rings Worn/
Damaged.6. Remove and disassemble transmission.
Replace seal rings and any other worn or
damaged parts.
