ok my antifreeze turn dirty brown right after i flush and fill it. it seems to my my transmission cooler inside the raditor leaking and tainting the coolant. is this so and if it is does the tranny cooler come already inside a new radiator if i buy one to fix this!?!?!?!?

thanks in advance
Ben

 

Trans fluid is oil and antifreeze is water based, so they would not mix. If it's trans fluid it would not be brown coolant, but rather green coolant and brown streaks of trans fluid. It sounds like you might need to keep flushing that cooling sys, sounds like there's just lots of rust and other crap in it.
No you can't buy just the trans cooler, it comes with the rad as one piece. Worst case scenario is you buy an aftermarket trans cooler and disconnect the stock one, but that shouldn't be neccessary bc I don't think that that's the problem.
Hope this helps...
