1) Apply a thin coat of ATF to the oil seal part of
new ATF filter.
2) Install the ATF filter. Turn it by hand, being care-

T1: 14 N·m (1.4 kgf-m, 10.1 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST length 78 mm (3.07 in)
L2: Torque wrench length
Example:
Torque wrench length
mm (in)
100 (3.94)
150 (5.91)
200 (7.87)
NOTE:
Attach ST to the torque wrench as straight as pos-
