Mitsubishi Outlander XL. Manual - part 1263

Low clutch

Composed of the clutch drum, piston, spring retainer assembly, drive plate, driven
plate, and others. It links the plates by the hydraulic operation of piston, and transfers
the power to the front internal gear.

3-5 reverse clutch

The components are the same as for the low clutch. It links the plates by the hydraulic
operation of piston, and transfers the power to the front sun gear.

High clutch

The components are the same as for the low clutch. It links the plates by the hydraulic
operation of piston, and transfers the power to the rear carrier.

Low  and  reverse
brake

Composed of the piston, spring retainer assembly, drive plate, driven plate, and others.
It links the plates by the hydraulic operation of piston, and fixes the rear carrier.

2-6 brake

The components are the same as for the low and reverse brake. It links the plates by
the hydraulic operation of piston, and fixes the rear sun gear.

Input shaft

It is spline-engaged with the reduction carrier. It transfers the power from the torque
converter. For the shaft inner hole, there are the lubricant supply hole for the each
sliding area inside the unit and the hydraulic pressure distribution hole for the lock-up
ON-OFF.

Front planetary gear Composed of the carrier, sun gear, and internal gear. It increases or decreases the

output rotation in relation to the input by fixing or releasing the carrier, sun gear, and
internal gear.

Rear planetary gear The components are the same as for the front planetary gear. By fixing or releasing

the carrier, sun gear, and internal gear, it increases or decreases the output rotation
in relation to the input, and switches the rotation direction between normal and reverse.

Reduction  planetary
gear

The components are the same as for the front planetary gear. By fixing or releasing
the carrier, sun gear, and internal gear, it increases or decreases the output rotation
in relation to the input.

4-point gear

The power is transferred from the rear internal gear to the output gear → idler gear
→

 reduction pinion gear → final gear.

Valve

 body

assembly

Controls the original pressure from the oil pump to the suitable hydraulic pressure for
the  line  pressure  control  system,  shift  control  system,  lock-up  control  system,  and
lubrication system.

Dish plate and high-load wave plate
In order to reduce the shock at the engagement, the
"dish plate" with elastic effect has been adopted to the
high clutch and low clutch. Also, the "high-load wave
plate" with the similar effect has been adopted to the
2-6 brake and 3-5 reverse clutch.

Centrifugal cancel chamber
With  this  A/T,  a  "centrifugal  cancel  chamber"  that
faces  all  the  clutch  chambers  is  used.  To  the
"centrifugal cancel chamber," the transmission fluid is
always  charged  via  the  special  oil  passage  of  oil
pump.
