  • Before changing the transmission fluid, it is better to take a small drive so that the fluid becomes warm.
  • Park the car on a flat surface and apply the parking brake. Better to put logs or wooden blocks behind the rear wheels.
  • Lift the front of the vehicle up with floor jack and rest the vehicle on jack stands to ensure the safety.
  • Take a large drain pan and put it under the transmission oil pan. Break loose the bolts holding the transmission pan cover to the transmission pan. Make sure you don’t take the bolts away completely. You may need to pry the gasket and pan as they both stuck to each other tightly.
  • Observe the drained fluid with a thumb and finger. If you feel any metal particles in the fluid, you need to repair the transmission. If the fluid is free from any contaminants, simply add new fluid.
  • Take the old gasket away from the transmission pan and transmission. Clean or wash the transmission pan properly if required.
  • Take a gasket sealer and a new gasket and coat the new gasket and the transmission pan edges with the sealer. Place the gasket between the transmission and transmission pan edges and apply a little pressure so that gasket takes its place properly.
  • Secure the pan with transmission with bolts. Torque the bolts.
  • Take the jack stands away and lower the floor jack.
  • Prop up the engine hood and search for the transmission fluid dipstick.
  • Pull up the dipstick and put the funnel in the dipstick tube so that you can add new automatic transmission fluid into the transmission pan. Make sure that the new fluid is the recommended type for your vehicle.
  • Insert the dipstick and pull it back to check the fluid level. Add more fluid if required.
  • Close the hood and take a small drive. Check the transmission and transmission pan for any signs of leakage.
