i need a diagram of a 2003 dodge neon automatic transmission
go to autozone and buy a haynes manual for around 15 dollars. If you cant find one for your neon, then I believe it has the same transmission as the 1995-99 neons so you should be able to use that book. hope this helps!!
additive won,t do you much good. what you need is a complete tune-up and make sure your tires are up to the right amount of air.
