If a hose looks bad, or feels too soft or too hard, it should be replaced. Check dodge durango transmission fluid monthly with engine warm and running, and parking brake on. Shift to drive, then to park. Remove dipstick, wipe dry, insert it and remove it again. Add the approved type fluid, if needed.
Check dodge durango oil every other fill up.
Remove the dipstick, wipe it clean. Insert it fully and remove it again. If it is low, add oil. To maintain peak performance, change oil every 3,000 miles or 3 months, whichever comes first. Replace oil filter with every oil change.
