The transmission fluid in my auto tranny in my 1981 eagle sx/4 is
milkshake - like and pink.I haven't found the cause yet, but will I need
to replace the transmission? Some people tell me I will, as the soluble
glue will fail. Others tell me that I will just need to find the radiator leak and
repair it, followed by a tranny flush.... some people are telling me to scrap the car.. yeah right!
any opinions? Thanks everyone!

The transmission pumps oil to and through the oil cooler in the radiator to help keep the trans cool. How is the color of the fluid after it sat a while with the engine off? A picture or two may help some of us figure out what is wrong, so that may be helpful to post. If the color of the fluid was a dark muddy brown/maroon, that would be the sign that the trans is at the end of it's life.

You may get lucky, I flushed water out of a trans years ago, and it's been holding up fine. I hope you haven't run it like that though.

I ran the AW4 in my Comanche for almost a year with ATF/antifreeze mix because it was too cold/wet and I was too sick to work on it. New rad had failed (plugged cooler) and external cooler was too late.

That's how I got my Limited. The original owner had the trans rebuilt a couple years before I got a hold of it. Another repair shop owner brought it by on his rollback, knowing I was an AMC guy. Asked if I was interested, he thought the tranny needed rebuilt again, the owner was fed up. I pulled the stick, saw the milkshake and decided to take the gamble. I flushed the trans with my machine, replaced the filter, installed an external cooler. That was back in 2003. Still runs strong today. I was going to take it to the local Sonic meet tonight but the weather turned better and the Rebel went instead! The Eagle: bad weather classic!

Thanks y'all for your help! I took your advice, flushed the trans, changed the filter, and put in a cooler. I didn't use a machine tho, I just disconnected the transmission hose from the radiator, then in neutral with it running I poured in new atf until it pissed red. once i felt like it was just spitting out clean atf I drained it, changed the filter, connected it up to the new trans cooler, and filled it back up. I did it this way cause my pan didn't have a release, so i could just drain it, I had to dilute it until all the pink was gone.
That should work right?

Yes, I've done quite a few tranny flushes that way, although ive had the pan off first. I am assuming the new cooler is external, so you should be good to go, I feel.

That should do. That's really what a trans machine does anyway. As long as you don't run it too low during the process, you're OK.
