tranny fluid help! 1999 Mustang GT

schwaebz98 · 03-05-2009

what color is a good color, i know it should be red, but a deep dark red? mines looking kind of pale. i drive a 99 auto GT

a freind of mine also told me that a transmisson gets used to the fluid it has in it, and if i get it changed, the transmisson may break

i would really like to flush the tranny and get some new fluid in it

Your friend is not 100% wrong.

I think in your case, as long as you do a flush, change the filter and use new fluid you will be ok. Mercon V

What your friend is talking about is cars that have not had the tranny fluid changed on a regular basis. ATF has detergents in the fluid, as the fluid gets old and breaks down, the detergent qualities of the fluid degrade, eventually to the point where it doesn't have any. On trannies that haven't had a regular fluid change, the parts are worn out, but the tranny still works ok. When you change the fluid on one of those trannies, the new fluid and the detergents in the fluid will wash away all the material thats left on the clutches and work up old contaminents in the tranny, and then it doesn't work so well anymore.

so how can i tell if my tranny is ok to flush? idk when it was flushed last

the fluid in it currently is all red, so there are no contaminets in it

As long as the fluid looks fairly clean the way it is, you will probably be ok. Its when its really dark, black or brown, thats when you have to worry.
