Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12. .

If readings are still inconsistent, contact the dealer. Automatic Transmission Fluid (6-Speed Transmission) When to Check and Change Automatic Transmission Fluid It is usually not necessary to check the transmission fluid level. The only reason for fluid loss is a transmission leak or overheated transmission. If a small leak is suspected, then use the following checking procedures to check the fluid level. However, if there is a large leak, then it may be necessary to have the vehicle towed to a dealer service department and have it repaired before driving the vehicle further. Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 11‑12. How to Add Automatic Transmission Fluid Refer to Recommended Fluids and Lubricants on page 11‑12 to determine what kind of transmission fluid to use. Using a funnel, add fluid down the transmission dipstick tube only after checking the transmission fluid while it is hot. A cold check is used only as a reference. If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It does not take much fluid, generally less than 0.5 Liter (1 Pint). Do not overfill. After adding fluid, recheck the fluid level as described under "How to Check Automatic Transmission Fluid," earlier in this section. When the correct fluid level is obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place. .
