Transmission sounds

[laurentj23]

Hey all! I just recently purchased an auto 240 sx 95. When i put it in reverse, i noticed there's some rattling noise. It stops when it's in n,d,d2. I check thr tranny dipsitck and the fluid isnt the right color.ill get it flushed soon.

Do you all have any clues as to what the cause of the noise is? It has only 125 k miles on it.

Thanks in advance.
