DRAINING & REFILLING
NOTE: Although manufacturer recommends changing only fluid, the
oil filter/screen may also require replacement. If replacing
oil filter/screen, note length and location of all bolts.
Transaxle (Except Montero)
1) Remove drain plug(s), and drain fluid. Some models may
contain a drain plug located in housing below axle shaft, in oil pan.
Remove oil pan. Remove oil filter/screen if necessary.
2) If oil filter/screen is replaced, tighten bolts to
specification. See TORQUE SPECIFICATIONS . Clean oil pan, replace
gasket, and install oil pan. Tighten oil pan bolts and drain plug to
specification. See TORQUE SPECIFICATIONS . Ensure dipstick hole area is
clean. Fill transmission with Diamond ATF SP-II, through filler tube,
until COLD level is reached on dipstick.
3) Start engine and allow to idle for 2 minutes. Shift
transaxle to each position, ending in Neutral. Add sufficient fluid to
reach lower mark. After reaching normal operating temperature, fluid
should be between upper and lower marks of HOT range on dipstick.
Transmission (Montero)
1) Remove drain plug (if equipped) from transmission pan, an\
d
allow fluid to drain. On models without drain plug, oil pan must be
Page 1359 of 1501
removed to drain fluid. Remove oil filter/screen if necessary.
2) If oil filter/screen is replaced, tighten bolts to
specification. See TORQUE SPECIFICATIONS . Clean oil pan, replace
gasket, and install oil pan. Tighten oil pan bolts and drain plug to
specification. See TORQUE SPECIFICATIONS . Ensure dipstick hole area is
clean. Fill transmission with Dexron-II ATF, through filler tube,
until COLD level is reached on dipstick. Start engine, and allow to
idle for 2 minutes.
3) Shift transmission into each position, ending in Neutral.
Check fluid level with engine running at idle. If necessary, add
sufficient fluid to bring level to lower mark of dipstick. Recheck
fluid level after transmission is at normal operating temperature.
Transfer Case
Drain plug is located on bottom of transfer case. Change
drain plug gasket whenever fluid is changed. Lubricant level should be
at bottom of fill hole on side of transfer case.
ADJUSTMENTS
KICKDOWN SERVO
Eclipse, Galant & 3000 GT
1) Remove all dirt and grease around kickdown servo switch.
Remove snap ring and kickdown servo switch.
2) To prevent servo piston from turning, install Adapter
(MD998915) and Kickdown Servo Wrench (MD998918) so tab of wrench
engages with notch of piston. See Fig. 1.
CAUTION: DO NOT push servo piston inward while installing adapter and
servo wrench. Install adapter in brake pressure port by hand
ONLY. DO NOT use wrench to tighten adapter.
