DESCRIPTION OF THE PROBLEM
The CVT warning lamp and a “SLOW DOWN” warning may display on the Multi-Information Display (M.I.D.) after driving at highway speeds during hot weather for long periods. The warnings will turn off after the vehicle is operated at reduced speeds, allowing the fluid to return to normal operating temperature. To correct this condition, reduce the CVT fluid level by 0.7 liters (0.75 qt.) and install a redesigned CVT fluid level gauge described in the PARTS INFORMATION section of this article.
Built before December 22, 2008.
HOW TO REPAIR THE PROBLEM
Begin this procedure with the engine and transmission cold.
- Install a redesigned transmission fluid level oil gauge (part number 2706A085 contact FactoryMitsubishiParts.com for this).
- Reduce the CVT fluid level in the transmission by 0.7L (0.75 qt.) as follows. Complete fluid replacement is not necessary.
- Raise the vehicle on a hoist.
- Loosen the CVT oil pan drain plug 2 or 3 turns and use a small screwdriver or pick to loosen the drain plug gasket from the oil pan.
- NOTE: Have a new drain plug gasket (part number 2705A012) unpackaged and ready to install onto the plug.Completely remove the drain plug and gasket. Drain approximately 1 quart of CVT fluid into a CLEAN container. DO NOT dispose of the fluid at this time.
- NOTE: An empty 1 qt. CVT container works well. CVT fluid must NOT be contaminated with dirt, regular A/T fluid or other oils. If using a funnel, make sure it also is clean and there is no residue of regular A/T fluid or other oils.Replace the gasket with the new one and reinstall the drain plug. Torque to 34 + 2 Nm (25 + 2 ft.-lbs.).
- Lower the vehicle and check the COLD CVT fluid level. Make sure the level is at the “C” range (cold) of the gauge. If necessary, add some of the drained fluid to bring it to the bottom of the “C” range.
- Drive the vehicle and allow it to warm up to normal operating temperature.
- Check the CVT fluid level per the service manual, Group 23A – CVT – Transmission Fluid Check:
- On the MUT-III, click on System Select, then select ELC-AT/CVT/TC-SST from the System Select Menu.
- Select the Data List and locate Item 20, Transmission Fluid Temperature. Confirm fluid temperature data is between 143 – 161 counts (70 – 80° C, 158 – 176°F).
- Use the container of removed fluid to adjust the fluid level to the “H” range (hot) of the new gauge. Properly dispose of excess fluid.
After completing the repair, drive the vehicle in all gears and confirm that the CVT (Constantly Variable Transmission) is operating as it should. With the vehicle in N (neutral), look underneath to confirm there is no CVT fluid leakage.
