The transmission started slipping the other day. I checked the fluid and it was low. I put fluid in it to notice later that it was leaking. Now even with the proper amout of fluid it is still slipping. It is also making a clicking noise, it makes the noise when it is idle and the ticking increases as i accelerate. but if it is in park it doesnt increase, only when I am giving it the gas as I am moving. Does anyone have any clue as to the problem, or what should I do.
