DODGE RAM SRT-10 2006 Service Repair Manual

In either case, air bubbles can cause overheating and/or fluid oxidation,and varnishing. This can interfere with nor-
mal valve, clutch, and accumulator operation. Foaming can also result in fluid escaping from the transmission vent
where it may be mistaken for a leak.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be sure to wipe all
dirt from dipstick handle before removing.
The torque converter fills in both the P(PARK) and N (NEUTRAL) positions. Place the selector lever in P (PARK)
to be sure that the fluid level check is accurate.The engine should be running at idle speed for at least one
minute, with the vehicle on level ground.At normal operating temperature (approximately 82° C. or 180° F), the
fluid level is correct if it is in the HOT region (cross-hatched area) on theoil level indicator. The fluid level will be
approximately at the upper COLD hole of the dipstick at 21° C (70° F) fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this proce-
dure.
1. Start engine and apply parking brake.
2. Shift the transmission into DRIVE for approximately 2 seconds.
3. Shift the transmission into REVERSE for approximately 2 seconds.
4. Shift the transmission into PARK.
5. Hook up scan tool andselect transmission.
6. Select sensors.
7. Read the transmission temperature value.
8. Compare the fluid temperature value with the chart.
9. Adjust transmission fluid level shown on the dipstick according to the Transmission Fluid Temperature Chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully drain from
the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.

FLUID AND FILTER REPLACEMENT
For proper service intervals (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIP-
TION).
REMOVAL
1. Hoist and support vehicle on safety stands.
2. Place a large diameter shallow drain pan beneath the transmission pan.
3. Remove bolts holding front and sides of pan to transmission.
4. Loosen bolts holding rear of pan to transmission.
5. Slowly separate front of pan away from transmission allowing the fluid to drain into drain pan.
6. Hold up pan and remove remaining bolts holding pan to transmission.
7. While holding pan level, lower pan away from transmission.
8. Pour remaining fluid in pan into drain pan.
9. Remove the screw holding the primary oil filter (1)
to valve body.
10. Separate filter from valve body and oil pump and
pour fluid in filter into drain pan.
11. Inspect the oil filter seal in the bottom of the oil
pump. If the seal is not installed completely in the
oil pump, or is otherwise damaged, then remove
and discard the oil filter seal from the bottom of
the oil pump. If the seal is installed correctly and
is in good condition, it can be reused.
12. If replacing the cooler return filter (2), use Oil Fil-
ter Wrench 8321 to remove the filter from the
transmission.
13. Dispose of used trans fluid and filter(s) properly.
INSPECTION
Inspect bottom of pan and magnet for excessive amounts of metal. A light coating of clutch material on the bottom
of the pan does not indicate a problem unless accompanied by a slipping condition or shift lag. If fluid and pan are
contaminated with excessive amounts of debris, refer to the diagnosis section of this group.
CLEANING
1. Using a suitable solvent, clean pan and magnet.
2. Using a suitable gasket scraper, clean original sealing material from surface of transmission case and the trans-
mission pan.

INSTALLATION
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.
1. If necessary, install a new primary oil filter seal in
the oil pump inlet bore. Seat the seal in the bore
with a suitable tool (appropriately sized drift or
socket, the butt end of a hammer, or other suitable
tool).
2. Place replacement filter in position on valve body
and into the oil pump.
3. Install screw to hold the primary oil filter (1) to
valve body. Tighten screw to 4.5 Nꞏm (40 in. lbs.)
torque.
4. Install new cooler return filter (2) onto the transmission, if necessary. Torque the filter to 9.5 Nꞏm (7 ft.lbs.).
5. Place bead of Mopar
RTV sealant onto the transmission case sealing surface.
6. Place pan in position on transmission.
7. Install bolts to hold pan to transmission. Tighten bolts to 12 Nꞏm (105 in. lbs.) torque.
8. Lower vehicle and fill transmission with MOPAR
AT F + 4 .
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
ATF+4totransmission:
a. If only fluid and filter were changed, add10 pints (5 quarts)of ATF +4 to transmission.
b. If transmission was completely overhauled and the torque converter wasreplaced or drained, add24 pints
(12 quarts)ofATF+4totransmission.
3. Check the transmission fluid (Refer to 21 - TRANSMISSION/AUTOMATIC - RFE/FLUID - STANDARD PROCE-
DURE) and adjust as required.

OPERATION
2C CLUTCH
The 2C clutch is hydraulically applied in second and fifth gear by pressurized fluid against the 2C piston. When the
2C clutch is applied, the reverse sun gear assembly is held or grounded to the transmission case by holding the
reaction planetary carrier.
4C CLUTCH
The 4C clutch is hydraulically applied in second prime and fourth gear by pressurized fluid against the 4C clutch
piston. When the 4C clutch is applied, the reaction annulus gear is held or grounded to the transmission case.
LOW/REVERSE CLUTCH
The Low/Reverse clutch is hydraulically applied in park, reverse, neutral, and first gear, only at low speeds, by pres-
surized fluid against the Low/Reverse clutch piston. When the Low/Reverse clutch is applied, the input annulus
assembly is held or grounded to the transmission case.
