I'd change it out if you want it last a little longer. Since it's brown and not black, I'd say to change it, should be bright red, replace the filter too if your trans has one.


I agree. And if there's anything more than a trace of clutch material etc. in the pan gt it checked out. Those transmissions do like to fail and its big money to get them fixed. A little preventative maintenance goes a long way sometimes.
