1. Clean the reservoir cap before
removal to prevent dirt and
water from entering the
reservoir.
2. Remove cap and rubber
diaphragm from reservoir.
3. Add fluid until the level reaches
the step in the reservoir.
4. Reinstall rubber diaphragm and
cap onto reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to your service maintenance section for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it reaches normal
operating temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine
compartmentin this chapter for the location of the dipstick.

1Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. MERCONtand MERCONtV are not interchangeable. DO NOT
mix MERCONtand MERCONtV. Refer to the service maintenance
section to determine the correct service interval.
2Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick's normal operating range.
4Add the coolant type originally equipped in your vehicle. DO NOT MIX
different colors or types of coolant. DO NOT USE Extended Life Engine
Coolant (orange in color). Refer toAdding engine coolantin this
chapter.
5Traction-Lok axles use 2.2±2.4L (4.75±5.0 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier meeting Mazda
specifications for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.
