CAUTION!
When clutch disc, retaining plate and/or
separator plate of forward clutch have been
replaced, all learned contents, which have
been stored in TCM memory by executing
learning control, should be initialized
referring to “Learning Control Initialization”.
Neglecting this initialization may cause
excessive shift shock.

Disassembly
1) Remove reverse clutch plate snap ring (1) and take
out reverse clutch retaining plate, discs, separator
plates and clutch cushion plate from intermediate
shaft subassembly.2) Remove forward clutch plate snap ring (1) and take
out forward clutch retaining plate, discs and
separator plates from forward clutch drum.
3) Remove balancer snap ring by using special tool and
hydraulic press.
Special tool
(A): 09926–97610
CAUTION!
Do not press forward clutch return spring
subassembly in over 1.5 mm (0.059 in.).
Excessive compression may cause damage
to return spring subassembly and/or

One-way clutch No.1 assembly
1) Install one-way clutch No.1 assembly (2) to rear
planetary sun gear subassembly (1).
2) Securing rear planetary sun gear subassembly,

does not rotate in either direction, replace it with new
one.
Adjustment
Differential side bearing preload
1) After applying A/T fluid to differential assembly, fit it
to transaxle case.
2) Install torque converter housing to transaxle case,
then tighten bolts (1) to specified torque.
Tightening torque
Torque converter housing bolt (a): 33 N·m (3.3
kgf-m, 24.0 lb-ft)3) Measure bearing preload (a) by using a special tool.
Special tool
(A): 09928–06050
Differential side bearing preload (a) measured as
starting torque
In the case of new bearing: 0.78 – 1.37 N⋅m (7.9 –
13.9 kg-cm, 0.58 – 1.01 lb-ft)
In the case of reused bearing: 0.39 – 0.69 N⋅m
(3.9 – 6.9 kg-cm, 0.29 – 0.51 lb-ft)
4) If bearing preload is out of specification, select shim
with suitable thickness from among the list below
and replace it. Then adjust differential side bearing
preload within specification.
