How to Change the Transmission Fluid on a ML430 Benz

1. Park the ML430 on a flat surface and make sure the engine is cool. If the car has been driven recently, wait at least 30 minutes for the heat to dissipate. Raise the car on jack stands to reach the underside of the engine more easily. Slide under the car and locate the transmission drain pan. It is a large, metal tank held with eight bolts beneath the middle of the engine.
2. Place a collection pan beneath the drain pan. Use the 1/2-inch socket wrench to remove all but one bolt on the drain pan. Wait 10 to 15 minutes for the fluid to drain into the collection pan. When it stops spilling from the side, place one hand on the drain pan and remove the final bolt. Lower the pan and pour the remaining fluid into the collection pan. Wash out the drain pan and bolts.
3. Remove the transmission filter under the drain pan with the 3/8-inch socket wrench. Attach the new transmission filter with the same bolts removed from the old one. Reattach the drain pan and lower the car from the jack stands.
4. Pop the engine hood by pulling the hood-release lever underneath the steering panel. Locate the yellow transmission dipstick above the drain pan. Pull it out and place a funnel into the tube. Pour in three quarts of five-speed transmission fluid. Replace the dipstick and close the engine hood.
5. Pour the used transmission fluid into a leak-proof container and take it to a recycling center. Many auto repair and auto parts shops also accept used car fluids.
