DODGE RAM SRT-10 2006 Service Repair Manual

OPERATION
The three input clutches are responsible for driving different components of the planetary geartrain.
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in first, second, second prime, and third (direct) gears by pressurized
fluid against the underdrive piston. When the underdrive clutch is applied, the underdrive hub drives the input sun
gear.
OVERDRIVE CLUTCH
The overdrive clutch is hydraulically applied in third (direct), fourth,and fifth gears by pressurized fluid against the
overdrive/reverse piston. When the overdrive clutch isapplied, the overdrive hub drives the reverse carrier/input
annulus assembly.
REVERSE CLUTCH
The reverse clutch is hydraulically applied in reverse gear by pressurized fluid against the overdrive/reverse piston.
When the reverse clutch is applied, the reaction annulus gear is driven.
DISASSEMBLY
NOTE: If the input clutch assembly is being reconditioned (clutch/seal replacement) or replaced, it is nec-
essary to perform the Quick Learn Procedure using the scan tool (Refer to 8 -ELECTRICAL/ELECTRONIC
CONTROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE).

15. Using Spring Compressor 8251 (2) , compress
the UD/OD balance piston (3) and remove the
snap-ring from the input clutch hub.

16. Remove the UD/OD balance piston (6) and piston return spring (9) from the input clutch retainer (13).
17. Remove the underdrive piston (8) from the input clutch retainer (13).
NOTE: Both the UD/OD balance piston and the underdrive piston have seals molded onto them. If the seal
is damaged, do not attempt to install a new seal onto the piston. The piston/seal must be replaced as an
assembly.
18. Remove the input clutch retainer tapered snap-ring (5).
19. Separate input clutch retainer (13) from input clutch hub (1).
20. Separate OD/reverse piston (15) from input clutch hub retainer (13).
21. Remove all seals and o-rings from the input shaft and input hub. The o-rings on the input hub are color coded.
Be sure to make note of which o-ring belongs in which location.

ASSEMBLY
NOTE: Install all new seals and o-rings onto the input shaft and input hub. The o-rings on the input hub are
color coded. Be sure to install the correct o-ring in the correct location.
1. Check the transmission lubrication check valve (20) located in the input shaft using shop air. The valve should
only allow air flow in one direction. If the valve allows no air flow, or air flow in both directions, the valve will need
to be replaced.
2. Lubricate all seals with Mopar
ATF +4, Automatic Transmission Fluid, prior to installation.
3. Assemble the OD/reverse piston (15) onto the input clutch hub (1).
4. Assemble the input clutch retainer (13) onto the input clutch hub (1).
5. Install the input clutch retainer tapered snap-ring (5) with tapered side up onto the input clutch hub (1).

6. Install Piston Installer 8504 (1) into the input clutch
retainer and onto the input clutch hub to guide the
inner and outer underdrive piston seals into posi-
tion.
7. Install the underdrive piston into the input clutch
retainer and over the input clutch hub.
8. Install the UD/OD balance piston return spring pack
into the input clutch retainer.
9. Install Piston Installer 8252 (1) into the input clutch
retainer to guide the UD/OD balance piston seal
into position inside the underdrive piston.
10. Install the UD/OD balance piston (3) into the input
clutch retainer and the underdrive piston.
11. Using Spring Compressor 8251 (2), compress the
UD/OD return spring pack and secure the piston
in place with the snap-ring.
12. Install the underdrive clutch pack into the input
clutch retainer.

13. Install the UD/OD reaction plate lower flat snap-ring (16). The correct snap-ring can be identified by the two
tabbed ears.
14. Install the UD/OD reaction plate (15) into the input clutch retainer. The reaction plate is to be installed with the
big step down.
15. Install the UD/OD reaction plate upper tapered snap-ring (14) with tapered side up.

16. Install the input clutch assembly into Input Clutch
PressureFixture8260(2).
17. Mount a dial indicator to the assembly, push down
on the clutch discs and zero the indicator against
the underdrive clutch discs. Apply 20 psi of air
pressure to the underdrive clutch and record the
dial indicator reading. Measure and record UD
clutch pack measurement in four (4) places, 90°
apart. Take average of four measurements and
compare with UD clutch pack clearance specifica-
tion. The correct clutch clearance is 0.84-1.54 mm
(0.033-0.061 in.). The reaction plate is not selec-
tive. If the clutch clearance is not within specifica-
tion, replace the reaction plate along with all the
friction and steel discs.

18. Install the overdrive clutch pack (13) into the input clutch retainer.The overdrive steel separator plates can be
identified by the lack of the half-moon cuts in the locating tabs.
19. Install the overdrive clutch wavy snap-ring (3) with the two tabbed ears into the input clutch retainer.
20. Install the OD/reverse reaction plate (4) into the input clutch retainer. The reaction plate is non-directional.
21. Install the OD/reverse reaction plate flat snap-ring (6) into the input clutch retainer.
