Mitsubishi recommends the use of Mercon®automatic transmission fluid.
The transaxle dipstick is located behind the air inlet hose, towards the firewall.
- Park the vehicle on a level surface.
- The transaxle should be at normal operating temperature when checking fluid level. To ensure the fluid is at normal operating temperature, drive the vehicle at least 10 miles.
- With the selector lever in P and the parking brake applied, start the engine.
- Open the hood and locate the transaxle fluid dipstick. Pull the dipstick from its tube, wipe it clean, and reinsert it. Make sure the dipstick is fully inserted.
- Pull the dipstick from its tube again. Holding it horizontally, read the fluid level. The fluid should be between the MIN and MAX mark. If the fluid is below the MIN mark, add fluid through the dipstick tube.
- Insert the dipstick, and check the level again after adding any fluid. Be careful not to overfill the transaxle.
DRAIN & REFILL
- Raise and support the vehicle safely.
- Place a suitable drain pan under the transaxle drain plug.
- Remove the transaxle pan drain plug. Let the fluid completely drain out of the transaxle.
- Install the drain plug and tighten it to 22-25 ft. lbs. (30-35 Nm).
- If equipped, remove the drain plug on the differential of the transaxle.
- Install the differential drain plug and tighten it to 22-25 ft. lbs. (30-35 Nm).
- Remove the drain pan.
- Lower the vehicle.
- Fill the transaxle through the dipstick to the proper level.
- Place the gear selector lever in P and start the engine. Run the engine at idle, engage the emergency brake and hold the brake pedal down. Move the gear selector lever through all transaxle ranges for approximately 5 minutes.
- Return the selector lever to P and leave the engine running at idle.
- Check the transaxle fluid level. The fluid level at normal operating temperature should read within the crosshatched area of the fluid level dipstick.
- If the fluid level reads below the crosshatched area, adjust the level by adding fluid in small increments until the correct fluid level is obtained.
PAN & FILTER SERVICE
The fluid should be changed according to the schedule in the Maintenance Intervals chart. If the car is normally used in severe service, such as stop and start driving, trailer towing, or the like, the interval should be halved. If the car is driven under especially nasty conditions, such as in heavy city traffic where the temperature normally reaches 90°F (32°C), or in very hilly or mountainous areas, or in police, taxi, or delivery service, the fluid should be changed according to the severe service schedule.
The fluid must be hot before it is drained; a 20 minute drive should accomplish this.
- Raise and safely support the vehicle.
- Drain the fluid from the transaxle. See the procedure above.
- Place a drain pan underneath the transaxle pan, then remove the pan attaching bolts.
- If the pan is stuck on the transaxle, very carefully pry the pan loose on one corner. You can use a small prybar for this if you work CAREFULLY. Do not distort the pan flange, or score the mating surface of the transaxle case. You'll be very sorry later if you do.
- Remove the pan and gasket.
- Clean the pan with solvent and allow it to air dry. If you use a rag to wipe out the pan, you risk leaving bits of lint behind, which will clog the dinky hydraulic passages in the transaxle.
- Remove the filter retaining bolts and remove the filter from the valve body.
- Install a new filter, then install the retaining bolts and tighten them to 5 ft. lbs. (7 Nm).
- Position the gasket on the pan, then install the pan. Tighten the bolts evenly and in rotation to 8-9 ft. lbs. (10-12 Nm.). Do not overtighten.
- Lower the vehicle.
- Add the recommended automatic transaxle fluid to the transaxle through the dipstick tube. You will need a long necked funnel, or a funnel and tube to do this. A quick check of the capacities chart later in this Section will reveal the capacity of the transaxle in your vehicle. On a first fill after removing the pan and filter, this number should be cut into a 1 / 3 and checked on the dipstick before refilling.
- With the transaxle in P , put on the parking brake, block the front wheels, start the engine and let it idle. DO NOT RACE THE ENGINE. DO NOT MOVE THE LEVER THROUGH ITS RANGES.
- With the lever in Park, check the fluid level. If it's OK, take the car out for a short drive, park on a level surface, and check the level again, as outlined earlier in this section. Add more fluid if necessary. Be careful not to overfill, which will cause foaming and fluid loss.
