26) Apply A/T fluid to 2nd brake piston assembly (1), and
align the projection of 2nd brake piston assembly
with the groove of transaxle case, then put together.
27) Install 2nd brake piston snap ring (1) by using
special tool and hydraulic press.
CAUTION!
Do not damage 2nd brake piston assembly,
return spring subassembly, plates and discs
by pressing in 2nd brake assembly passing
through its original installing position over
0.4 mm (0.016 in.).

Special tool
(A): 09926–96050
28) Check 2nd brake piston stroke by measuring
clearance between 2nd brake separator plate (1)
and piston (2) with feeler gauge (3).
If clearance, that is, piston stroke is out of
specification replace clutch discs and plates with
new ones.
CAUTION!
When brake disc, retaining plate and/or
separator plate of 2nd brake 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.

2nd brake piston stroke
Standard: 0.40 – 1.25 mm (0.016 – 0.049 in.)
29) After applying A/T fluid to front sun gear thrust
bearing race (2), install it to front planetary sun gear
(1).
30) Apply A/T fluid to front planetary sun gear (1) and
install it to planetary gear assembly (2).

43) Measure O/D and 2nd coast brake piston stroke.
• Measure dimension “a” from end face of transaxle
case to O/D and 2nd coast brake rear plate (1)
using straightedge and micrometer caliper.
• Measure dimension “b” from O/D and 2nd coast
brake piston (2) to rear cover assembly mating
surface using straightedge and micrometer
caliper.
• Calculate piston stroke from measured value of
dimensions “a” and “b”.
• Piston stroke = “a” – “b”
O/D and 2nd coast brake piston stroke
Standard: 0.65 – 1.05 mm (0.026 – 0.041 in.)
When piston stroke is out of specification, select O/D
and 2nd coast brake rear plate with proper thickness
from among the following table and replace it.
CAUTION!
When brake disc, retaining plate, separator
plate and/or rear plate of O/D and 2nd coast
brake 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.

44) After applying A/T fluid to new 2nd brake gaskets (1),
install them to transaxle case (2).
45) After applying A/T fluid to reverse clutch drum thrust
bearing (1), install it to forward and reverse clutch
assembly (2).
46) Remove sealant attached to mating surface of
transaxle rear cover (1) completely.
47) Apply sealant to mating surface of transaxle rear
cover (1) by using a nozzle (2) as shown in figure by
such amount that its section is 1.2 mm (0.047 in.) in
diameter.

and each other terminal at torque sensor connector.
• Wiring harness resistance of “Torque sensor power
supply circuit” is less than 1 Ω.
• Insulation between “Torque sensor power supply
circuit” and vehicle body ground is infinity.
