Automatic Transmission Fluid Change

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Transmission fluid

If you experience shifting problems with the automatic transmission, you need to flush and replace the fluid. The necessary tools are: digital thermometer, level, wrenches, screwdrivers, torque wrench, and a pump for fluid input. Lift the vehicle on a lift. Use the level to ensure the vehicle is perfectly level. Unscrew the oil drain plug located on the transmission pan and let it drain into a suitable container. Remove the oil pan where you notice metallic debris on the magnets. Clean thoroughly and reinstall the pan, replacing the gasket. Use the torque wrench to tighten the bolts. Add the flushing additive and use the appropriate equipment to perform a thorough flush, starting the engine and monitoring the temperature in the pan, then let it drain. After flushing, refill the transmission with the correct amount of the specified fluid.
