1 Answer


On flat surface. If not you can't tell how much is in the transmission. Start the car let it warm up to operating temperature, with the engine running pull the transmission dip stick out not the oil look at the fluid level on the stick, there's a section that is where the fluid level needs to be, and there should be a line that says FULL!! Do Not Over Fill. If it is low, check the owners manual if there's not a little sticker under the hood telling you about what kind of engine oil to use, what kind of Transmission Fluid to Use, with the engine still running add transmission fluid until it is at the correct level without over filling. If you haven't done this before, your going to need a transmission funnel. It is a long skinny funnel, parts store will help you out. Personally I would get one from Wally World before the parts store. Also better Transmission fluid and Oil prices than parts store.
