and remove. Disconnect all external solenoid and switch connections.
3) On Montero 4WD, remove catalytic converter and front
exhaust pipe. On all models, disconnect speedometer cable and control
cables at transmission. Remove starter and bellhousing cover. Place
reference mark on torque converter and drive plate for reassembly
reference. Remove torque converter bolts. Push torque converter back
and away from drive plate.
4) Disconnect transmission cooler lines. Remove oil filler
tube. Secure transmission on a jack. Raise transmission slightly to
take weight off mount. Remove crossmember-to-mount bolts and
crossmember.
5) Remove transfer case mounting bracket and mount (if
equipped). Remove transmission-to-engine mounting bolts. Carefully
lower transmission from vehicle.
CAUTION: Ensure torque converter is fully seated in transmission
before installation.
Installation
1) To install, reverse removal procedure. Tighten
transmission-to-engine bolts and torque converter-to-drive plate bolts
to specification. See TORQUE SPECIFICATIONS. Tighten mount bolts with
weight of engine and transmission on mounts. Ensure reference marks on
drive shaft(s) and torque converter-to-drive plate are matched.
2) Apply sealant to transfer case gearshift assembly gasket
before installation. Coat transmission oil filler tube "O" ring with
transmission fluid before installation. Refill transmission fluid to
specified level. See LUBRICATION in TRANSMISSION SERVICING - A/T
article. Adjust all control cables. See ADJUSTMENTS in
TRANSMISSION SERVICING - A/T article.

LUBRICATION
SERVICE INTERVALS
Transaxle/Transmission
Check fluid level every 12 months or 15,000 miles. Change
fluid and filter every 30,000 miles. If vehicle is operated under
severe conditions, change fluid more often. If severe darkening of
fluid and strong odor are noted, bands should also be adjusted.
Transfer Case
On 4WD and AWD models, change transfer case fluid every 30,
000 miles.
CHECKING FLUID LEVEL
Transaxle/Transmission
1) Park vehicle on level area. Ensure oil is at normal
operating temperature, parking brake is engaged, and engine is at
idle. Move gear selector through each position, stopping briefly at
each selection.
2) Place gear selector in Neutral, and clean area around
dipstick tube. Ensure fluid level is between lower and upper marks,
but never over upper mark, in HOT range. Add or drain fluid if
necessary.
CAUTION: If severe darkening of fluid and strong odor are noted,
change fluid and filter, and adjust bands.
Transfer Case (All Others)
Page 1358 of 1501
Lubricant level should be to bottom of fill hole on side of
transfer case.
RECOMMENDED FLUID
Transaxle/Transmission
Except Montero, use Diamond ATF SP-II. On Montero, use
Dexron-II ATF.
Transfer Cases
Use SAE 75W-85 gear oil with API GL-4 rating or higher.

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.
