Transmission

Park vehicle on level ground. Apply parking brake. Warm engine to normal operating temperature. Briefly place selector lever in all gears, and then return to "P" position. Clean dipstick and insert in tube. Remove dipstick. On B-Series and 626, fluid level should be within crosshatched area on dipstick. On all others, fluid level should be between top and bottom notches on dipstick near bottom. Check fluid for discoloration and unusual smell. If necessary, add fluid. DO NOT overfill.

Transfer Case (B-Series 4WD)

Remove oil fill plug. If fluid is level with opening, install fill plug. If fluid is low, fill until fluid is level with fill plug opening. Install plug.

Transmission (B-Series)

Use Mazda ATF Type 5 or equivalent.

Transmission (Except B-Series)

Use Mercon III or M-III ATF.

Transfer Case (BW 1354)

Use Mercon III or M-III ATF.

Move gearshift lever through all positions ensuring no components interfere with gearshift lever.

Scheme 16

INTERMEDIATE & OVERDRIVE BAND

Raise and support vehicle. Remove shifter cable and transmission range sensor. Remove and discard band lock nut. Using torque wrench, tighten band adjustment screw to 10 ft. lbs. (14 N.m). Back off band adjustment screw exactly 2 turns, and hold it so that it does not turn. Apply petroleum jelly to lock nut seal, and install NEW band lock nut. While holding band adjustment screw stationary, tighten band lock nut to 35-45 ft. lbs. (48-61 N.m). (Scheme 17) Install shifter cable and transmission range sensor. Lower vehicle.
