IMHO you would be better recycling it for scrap.

the trans is getting warm. i thought it might be the bypass valve but now im thinking it wasnt it and now im out $56
, so now its gotta be a plug somewhere. i knew it had a cooler between the rad and intercooler but didnt know about the one in the rad. so how do i go about flushing them both?

So the late model goes into the rad and then into an external cooler? I thought the late models just used the rad as a cooler.
Either way, disconnect the lines and run some brake-kleen through there (a few cans ought to do the trick).

The only way to make plugged coolers work is to replace them.

The early trucks ('99-mid 2000) only had the air to oil out front, nothing in the radiator. All trucks since mid-2000 have both.
There is NO way to flush a cooler. You can make the trapped particles cleaner with brake clean, but you can't get them out. Some of them will eventually work loose and cause problems in the trans.
