(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

tor.
(e) Move input shaft in and out and record read-
ing. End play should be 0.3-0.5 mm (0.012-0.020
in.). Adjust as necessary.(33) Install the output shaft washer onto the out-
put shaft.
(34) Install a new transmission rear seal into the
transmission case with Seal Installer 8902A (1) (Fig.
59).
