Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take your vehicle to a dealer/ retailer and have it repaired as soon as possible. Change the fluid and filter at the intervals listed in the Maintenance Schedule. See Scheduled Maintenance on page 7‑3. Be sure to use the transmission fluid listed in Recommended Fluids and Lubricants on page 7‑11. Notice: Use of the incorrect automatic transmission fluid may damage the vehicle, and the damages may not be covered by the vehicle's warranty. Always use the automatic transmission fluid listed in Recommended Fluids and Lubricants on page 7‑11. Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to a dealer/retailer for service. Have it repaired as soon as possible. You may also have the fluid level checked by your dealer/retailer when the oil is changed. See Recommended Fluids and Lubricants on page 7‑11 for the proper fluid to use.
