IDENTIFICATION

Note. On models with anti-theft radio system, obtain code number from customer to deactivate radio anti-theft system BEFORE disconnecting negative battery cable. To deactivate radio anti-theft system, turn ignition switch to ACC position. Press FF and REW buttons simultaneously until "cod e" is displayed. Press FF and REW buttons again until 4 bars are displayed. Use preset button No. 1 to enter first number. Use preset buttons No. 2, 3 and 4 to set other numbers. Press FF and REW buttons for about 2 seconds until a beep is heard. After 5 seconds, flashing "cod e" will go away and radio will operate.

AUTOMATIC TRANSMISSION APPLICATIONS

TRANSFER CASE APPLICATIONS

Transmission Fluid

Check fluid level every 7500 miles or 6 months. Replace transmission fluid every 60,000 miles for normal driving conditions and every 30,000 miles for severe driving conditions.

Transfer Case Fluid

Replace transfer case oil every 60,000 miles for normal driving conditions and every 30,000 miles for severe driving conditions.

Transmission

Park vehicle on level ground. Apply parking brake. Warm engine to normal operating temperature. Briefly place selector lever in all gears and return it to "P" position. Clean dipstick and insert it in tube. Remove dipstick. Level should be between "L" and "F" marks. Check fluid for discoloration and unusual smell. If necessary, add fluid. DO NOT overfill.

Transfer Case (4WD)

Remove fluid level check (lower) plug from side of transfer case. If fluid drains out or is level with opening, install plug. If fluid is low, remove fill plug above and to left of level check plug opening. Fill until fluid is level with lower plug opening. Install plugs.

Use Dexron-II or M-III ATF.

More than 50°F (10°C), use SAE 80W-90; less than 50°F (10°C), use SAE 75W-90.

4. Connect solenoid valve connector, and install harness. Clean oil pan, and install it using NEW pan gasket. Tighten pan bolts to specification.
5. Install vacuum diaphragm, and connect vacuum hose. Connect negative battery cable. Add fluid, and check level. DO NOT overfill.

3.0L

Loosen lock nut on band adjusting bolt. (Scheme 2) Tighten bolt to 35-53 INCH lbs (4-6 N.m). Loosen band adjusting bolt 2 1/2 turns. Tighten lock nut to 24-31 ft. lbs. (32-42 N.m).

Scheme 2

OVERDRIVE BRAKE BAND

Note. Overdrive brake band is not adjustable on 3.0L.

2.6L

1. Remove overdrive band servo cover and gasket. (Scheme 3) Loosen overdrive adjustment screw lock nut while holding piston stem stationary. Tighten piston stem to 61-87 INCH lbs. (7-10 N.m).
2. Back off piston stem 2 turns. While holding stem in this position, tighten lock nut to 11-30 ft. lbs. (15-40 N.m). Install overdrive band servo cover with NEW gasket. Tighten cover bolts to 44-62 INCH lbs. (5-7 N.m).

Scheme 3

Scheme 4

1. Kickdown and 4-3 switch is located on upper part of accelerator pedal. To adjust kickdown section of switch, use steps 2) and 3). To adjust 4-3 section of switch, use steps 4) and 5).
2. Connect a voltmeter between terminal "C" and ground. (Scheme 4) Turn ignition on. Depress accelerator pedal fully. Voltmeter should read less than 1.5 volts until pedal is at least 7/8 depressed. Battery voltage should be present at or after 7/8 pedal travel.
3. If voltage is not correct, disconnect switch and check continuity between terminals "C" and "D" when tip of switch is depressed.24-.26" (6.0-6.5 mm). If continuity is not present, replace switch. If continuity is present, adjust switch until battery voltage is present at 7/8 of pedal travel.
4. Connect voltmeter between terminal "A" and ground. (Scheme 4) Turn ignition on. Depress accelerator pedal to limit. Voltmeter should read less than 1.5 volts until pedal is at least 3/4 depressed. Battery voltage should be present at or after 3/4 of pedal travel.
5. If voltage is not correct, disconnect switch and check continuity between terminals "A" and "B" when tip of switch is depressed.14-.18" (3.5-4.5 mm). If continuity is not present, replace switch. If continuity is present, adjust switch until battery voltage is present at 3/4 of pedal travel.

GEARSHIFT LINKAGE

1. Move gearshift lever to "P" position. Remove steering column covers. Pull gearshift lever rearward and insert a.20" (5.0 mm) diameter pin into gearshift rod assembly. (Scheme 5)
2. Remove air intake pipe. Loosen shift lever bolts and top lever bolts. (Scheme 6) Place manual shaft in "P" position. Slide shift lever assembly until vertical clearance between shift lever bushing and lower bracket is zero. (Scheme 7)
3. Tighten shift lever bolts to 12-17 ft. lbs. (16-23 N.m). Ensure detent ball is in center of "P" range detent. (Scheme 8) Loosen mounting bolts and rotate bracket to adjust detent ball placement. Tighten detent mounting bolts to 61-87 INCH lbs. (7-10 N.m).
4. Rotate top lever until horizontal clearance between rear of shift lever bushing and lower bracket is zero. (Scheme 7) Tighten top lever bolts to 12-17 ft. lbs. (16-23 N.m). Remove pin from gear shift assembly. Install column covers. Check gearshift selector lever operation.

Scheme 5

Scheme 6

Scheme 7

Scheme 8

1. If vacuum diaphragm (modulator) is replaced, vacuum diaphragm rod length (depth) must be checked for new rod length. Proper length rod should be installed after measurement.
2. Unscrew the vacuum diaphragm from the case. Remove diaphragm, diaphragm rod and rubber "O" ring. Measure dimension "N" using Adjusting Gauge (49-G032-355). (Scheme 9) Also, refer to the «VACUUM DIAPHRAGM ROD SELECTION»(/mazda/mpv/v-1986-1991/remont/automatic-trans/#servicing-at) table to select proper length rod.

NEUTRAL SAFETY SWITCH

1. Place gearshift lever in "N" position. Ensure gearshift linkage is adjusted correctly. See «GEARSHIFT LINKAGE»(/mazda/mpv/v-1986-1991/remont/automatic-trans/#servicing-at__gearshift-linkage) under ADJUSTMENTS. Loosen neutral safety switch mounting bolts at transmission. Remove screw from alignment pin hole at bottom of switch (if equipped).
2. On 3.0L, rotate switch and insert a 5/32" (4.0 mm) alignment pin (or drill bit) through alignment holes. On 2.6L, insert a 5/64" (2.0 mm) alignment pin (or drill bit) through alignment holes.
3. On all models, tighten mounting bolts to specification. See «TORQUE SPECIFICATIONS»(/mazda/mpv/v-1986-1991/remont/automatic-trans/#servicing-at__torque-specifications) . Remove alignment pin.
