904 automatic transmission

[blakealbano]

Hi, I have a 71 Dart with a 904 automatic transmission and transmission fluid keeps overflowing out of the dipstick tube. Has anyone had or heard of this problem? Any help would be appreciated.

Thanks, Blake

what does the fluid read on the dipstick when its not running?

 

[blakealbano]

when its not running and cold, it reads about a half inch over the full mark, but when it is running and warm it reads about a half inch below the add mark

Is the fluid coming out from the top or around the bottom where it goes into the trans? And when does it do this?

 

[Bulldozer]

are you saying it is literally coming up and out of the top of dipstick tube where the fluid goes in?

 

[blakealbano]

Yes its coming up and out of the top of the dipstick tube where the fluid goes in

What does the fluid smell and look like ?

When fluid comes up the fill tube it usually because its overfull or overheated.

Check your cooler lines for restrictions (kinks,bends, etc.) also check the cooler.

Or the vent is plugged, dirt dobbers maybe? Are you sure it's the correct dipstick and tube?

Sounds like it's overfilled.

i would say you have a blockage somewhere out to the cooler or the return line. i would drop the pan, change the filter , unhook your pressure line and get some compressed air into the line and blow it all out and to make sure there are no obstructions. and only IF the fluid is nice and pink. if the fluid is brown and smells cooked, the trans may be about toasted.
