Where do you put n the transmission fluid in a 2000 dodge neon?

The transmission fluid dipstick for a 2000 Dodge Neon is located on the transmission itself. It's usually a short, relatively thin dipstick with a handle near the top of the transmission. It's often near the back of the engine compartment, but it's best to consult your owner's manual for the exact location. The manual will have diagrams and make it much easier to find. The dipstick itself will also usually be clearly marked.
