1) Get new ATF filter and apply a thin coat of ATF
to the oil seal.
2) Install ATF filter. Turn it by hand, being careful
not to damage oil seal.
3) Using ST, tighten ATF filter.
Calculate ATF filter torque specifications using the
following formula.
T2 = L2/(L1 + L2) × T1
T1: 14 N·m (1.4 kgf-m, 10.1 ft-lb)
[Required torque setting]
T2: Tightening torque
L1: ST length 0.078 m (3.07 in)
L2: Torque wrench length
