(29) Remove multiple-disc pack B3 (2) (Fig. 47)
and spring washer (3) by removing snap-ring (1) in
transmission housing. To facilitate removal of the
snap-ring (1), compress the multiple-disc pack B3 (2).
Note which clutch disc is removed just prior to the
spring washer (3) for re-assembly. If the clutch discs
are re-used, this disc must be returned to its original
position on top of the spring washer.
(30) Unscrew Torx socket bolts (7) (Fig. 47).
(31) Remove multiple-disc holding clutch B2 (4)
(Fig. 47) from transmission housing. The externally

NOTE: During the measurement the snap ring (7)
(Fig. 49) must contact the upper bearing surface of
the groove in the outer multiple-disc carrier (8).
NOTE: Pay attention to sequence of discs. If the
original clutch discs are reused, be sure to return
the disc identified on disassembly as belonging on
top of the spring washer (4) to its original location.
Place new friction multiple-discs in ATF fluid for
one hour before installing.
(4) Insert and measure spring washer (4) (Fig. 49)
and multiple-disc pack B3 (2, 6).
(a) Put multiple-discs for multiple-disc holding
clutch B3 together in the sequence shown in the
illustration and insert individually.
(b)
CAUTION: Apply only light pressure (less than 10 N
(3 lbs.) of force) to the clutch pack when measuring
the clutch clearance with the feeler gauge. Applying
excessive force to the clutch will give an incorrect
reading and lead to a transmission failure.Using a
feeler gauge, determine the play ªLº at three points
between the snap ring (7) and outer multiple-disc
(1). B3 clutch clearance should be 1.0-1.4 mm
(0.039-0.055 in.). Adjust the clearance as necessary.
(c) Adjust with snap-ring (7), if necessary. Snap-
rings are available in thicknesses of 3.2 mm (0.126
in.), 3.5 mm (0.138 in.), 3.8 mm (0.150 in.), 4.1 mm
(0.162 in.), 4.4 mm (0.173 in.), and 4.7 mm (0.185
in.).
(5) Check that the K1 clutch feed hole (1) (Fig. 50)
in the inner hub of clutch B1 is free before installing
clutch B1.

(6) Place intermediate plate (3) on converter hous-
ing (2) and align.
NOTE: The intermediate plate can generally be used
several times. The plate must not be coated with
sealant
(7) Install the holding clutch B1 (5) (Fig. 51) onto
the converter housing and intermediate plate.
Installed position of clutch B1 in relation to converter
housing is specified by a plain dowel pin in clutch B1
(arrow).
(8) Install the bolts to hold clutch B1 (5) (Fig. 51)
to the converter housing.
(9) Securely tighten multiple-disc holding clutch
B1 (5) on converter housing (2) to 10 N´m (88.5
in.lbs.).
(10) Install new torque converter hub seal (1) (Fig.
52) into the oil pump using Seal Installer 8902A.
(11) Install new oil pump outer o-ring seal onto oil
pump (Fig. 52).

(18) Using grease, install both Teflon rings in the
groove at the rear of the output shaft so that the
joint stays together.
(19) Mount transmission housing on converter
housing.
(20) Screw in Torx socket bolts through the trans-
mission housing into the converter housing. Tighten
the bolts to 20 N´m (177 in.lbs.).
(21) Measure end-play between park pawl gear
and grooved ball bearing in order to select the proper
geartrain end-play shim.
(22) Place Gauge Bar 6311 (1) on transmission
housing. Using a depth gauge, measure from the
gauge bar (1) to the parking lock gear (2) (Fig. 54).
(23) Using a depth gauge, measure from the
Gauge Bar 6311 (1) to the contact surface of the out-
put shaft bearing (2) in the transmission housing.
(Fig. 55)
(24) Subtract the first figure from the second fig-
ure to determine the current end-play of the trans-
mission. Select a shim such that the end-play will be
0.3-0.5 mm (0.012-0.020 in.). Shims are available in
thicknesses of 0.2 mm (0.008 in.), 0.3 mm (0.012 in.),
0.4 mm (0.016 in.), and 0.5 mm (0.020 in.).
(25) Install the selected end-play shim.(26) Screw in Torx socket bolts through the con-
verter housing into the transmission housing.
Tighten the bolts to 20 N´m (177 in.lbs.).
(27) Install output shaft bearing (2) in rear trans-
mission housing. Using Bearing Installer 9287 (1)
(Fig. 56), install the output shaft bearing (2) into the
transmission housing.The closed side of the plas-
tic cage must point towards the parking lock
gear.
(28) Install the retaining ring (1) (Fig. 57). Ensure
that the retaining ring is seated correctly in the
groove.
(29) Check that there is no play between the bear-
ing and the retaining ring using feeler gauge.
(30) There must be no play between the retaining
ring and the bearing. If the ring cannot be installed,
a thinner ring must be used. If there is play between
the ring and the bearing, a thicker ring must be
