If you are going to go about changing your transmission fluid all on your own there are a couple of different things you want to gather, most of which you can easily pick up at any local car shop. These include: A reliable maintenance guide for the specific make, model, and year of your vehicle. A set of heavy-duty jack stands or automotive maintenance ramps. Blocks to go behind your wheels so that your vehicle doesn't slide off the ramps or jacks. Hand tools that will allow you access to the transmission fluid pan and help you open it up to empty/refill the fluid. Brand-new high quality transmission fluid to replace the old fluid that you are going to be pulling out. A container where you’re going to be able to store all of the old transmission fluid in, before you dispose of it properly.
