Checking Fluid Level

CAUTION: Transmission fluid level should be checked when fluid is normal operating temperature to ensure fluid level is above ADD mark or lowest dimple on dipstick. Once fluid is above ADD mark, follow normal checking procedure.
  1. Transmission/transaxle temperature must be 150-170°F (66-77°C). With vehicle on level ground, apply parking brake, and run engine at idle. Move gearshift selector lever through all ranges, ending in Park.
  2. Fluid level should be in crosshatch area on dipstick. If transmission is at 50-95°F (10-35°C), fluid level should be between 2 dimples on bottom of dipstick.
  3. Add fluid as necessary. See RECOMMENDED FLUIDS . DO NOT overfill. Check condition of fluid for contamination and burned smell. Ensure dipstick is fully installed.
