         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)

         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, and

allow fluid to drain. On models without drain plug, oil pan must be

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.

         3) Loosen lock nut to "V" channel of adjuster rod. Tighten

inner section of Kickdown Service Adjustment Assembly (MD998916) until

it contacts lock nut. See Fig. 1.

         4) Install outer section of kickdown service adjustment

assembly on lock nut. Rotate outer section to left and inner section

to right to contact lock nut with inner section.

         5) Using an INCH-lb. torque wrench on inner section, tighten

inner section to 89 INCH lbs. (10 N.m), and then loosen inner section.

Tighten inner section to 44 INCH lbs. (5 N.m).

CAUTION: Before tightening lock nut with torque wrench, tighten it by

         hand until it contacts piston. If torque wrench is used

         initially, lock nut and adjustment rod may rotate together.

         6) Back off outer section 2-2 1/4 turns. Rotate outer section

to right and inner section to left until inner section is free of lock

nut. Tighten lock nut by hand until it contacts piston. Using torque

wrench, tighten lock nut to 18-23 ft. lbs. (25-32 N.m).

         7) Remove adapter and kickdown servo wrench. Install new "O"

ring in groove around switch. Install switch and snap ring.

         SHIFT LINKAGE

         Except Montero

         1) Ensure shift and transaxle/transmission levers are both in

Neutral position. Loosen adjusting nut on control cable. See  Fig. 2.

Loosen park/neutral position switch body bolts. Rotate park/neutral

position switch until hole in end of transmission manual control lever

is aligned with hole (cross section A-A) in flange of park/neutral

position switch body. Tighten park/neutral position switch body bolts.

Ensure holes in park/neutral position switch flange and transmission

manual control lever stay aligned.

         2) Gently pull control cable from dust cover. Make sure shift

lever is still in Neutral. Tighten adjusting nut. Check

transaxle/transmission operation through all ranges. Readjust control

cable if necessary.
