Hey guys I want to check the transmission cooler line check valve as i think it might be stuck, as for the 1st time yesterday the OD/off light came on and wouldnt go off and then a little while later (almost home) the trans temp come on, got home did some reading on here about the check valve and I think its stuck as my cooler lines were not hot. The tranny fluid and filter, sensors, solenoids, were all changed about a month ago by me, and the bands were adjusted. Anyways I think the tranny is ok as the fluid from yesterday still looks red and not burnt, and shifted fine when the lights on as I wasnt far from home. But anyways I have a 2000 ram 5.9 with tow package so i have the factory cooler between the rad and cond. and like I said the lines were not hot so i think the check valve is the issue, my question is on the pic i included is #1 pointing to the check valve correct and it runs into the bottom of the rad at #2, so to check the valve I unscrew the rubber line from the metal hard line going to the tranny and then do I unscrew the thread part going into the rad or do i disconnect the line from the screwed part in the rad? how do I do that i see no way to disconnect it. and then when I do disconect it will fluid poor out of the rad, if so what fluid will it be.. coolant?? or atf4? Thanks guys just trying to get info before i get fluid all over the ground.
well cutting it is not exactly what i want to do, because I know it can come apart from reading other forums, and that rubber hose with the check valve can be replace with a new piece from the dealer for about $40. I just want to know about takeing it off and will i lose fluid, like i asked in the 1st post.
It is a spring fitting. You can go to the local parts store and get the correct sized spring fitting tool to disassemble the "radiator" end of that piece of hose. It will fit over the diameter of the hard nipple coming out of radiator and push "into" the end of that hose, releasing the spring "teeth" that hold the hose end onto that nipple. Once you see it apart it's fairly simple...I'm sure my description is somewhat misleading/ambiguous.
You can get those spring fitting tools for fairly cheap, as many of them are made out of plastic. Nicer/fancier ones are made out of anondized aluminum.
EDIT: the rubber lines are plugged into the bottom of the radiator because that's where the main transmission heat exchanger/cooler are.
If your going to get the replacement part, go get it and see what it includes. My bet is it will be the entire thing from the radiator to the hard line. Once you see it I'm sure it won't be too hard to figure out how to get it apart. And yes, you will get ATF out of that line...

well i figured there wouldnt be coolant going into that line, but so atf4 accually flows thru part of the radiator??
Yes its a transmission cooler, it cools your transmission fluid. The fluid goes into the rubber line then into the bottom of the radiator, through a tube, it gets cooled, then out the top and back into another line back to the transmission.
