Used Transmission Coolers?

At the risk of sounding like a dumbass, I am asking this question. Why do people recommend not using used transmission coolers. I am looking for some cooling options for the transmission in my 00' 7.3 truck. I know everyone says to use the 6.0 cooler and I would love to do that, but I don't want to spend $300 on a new one. I have found some reasonably priced used ones but is there no way of flushing them out to get the possible contaminates out? Just can't figure out why the coolers can't be flushed?

Also, some say you can't hook up an additional cooler to the factory setup because it will cause to much restriction in the lines. What size are the factory 7.3 lines? IIRC the lines are 3/8", if that is the case why couldn't I just use a cooler with a 1/2" inlet and outlet? Would that still cause too much restriction?

So my questions are;

Can you clean a used cooler and clean it well?

Can you safely add a cooler to the factory system without causing to much restriction?

Before you ask, yes I am a cheap bastard and yes I want my cake and eat it too. Just looking for some budget options on keeping my tranny cool. Thanks for any responses.

Re: Used Transmission Coolers?

I would make sure if you get a used cooler that there was no metal contamination in the system from trans failure. If its from a good running truck with no issues(crased or otherwise) no problem. I installed a good clean used one in my 01 with no issues.

I see no problem as to why a good radiator shop couldn't boil it out for you or something like that.

Re: Used Transmission Coolers?

I don't recommend it because you haven't a clue about the cooler. Now if I were to get an F350 and decide to transplant my cooler, sure. I know the history. If you get it from me, all you have is my good word. Was it hit and say the plastic part cracked? What was the reason that trans cooler is for sale? Because Ford made the dealership install a new one as opposed to flushing it and now he has a "slightly used" cooler for sale?

Sure, you can flush and backflush it but the question is whether you are willing to take the risk on your trans or not. How much risk to your expensive trans are you willing to take? Are you sure there are no structural issues? You sure you got everything out of it that is there and there isn't a goober waiting to bite you afterwards? Too many uncertainties which is why I would buy a new one.

I'm cheap myself that is why I like to do it once and do it right. Because almost everytime I took the cheap way, it came back to bite me. A prime example is I skimped on my heads and saved a few hundred bucks. Big Time win. A couple years later, my (96 priced $5000) short block had a piston kiss a valve. So, what did I profit from that?

You can to that to mine or not, it will be fine. Once there is debris in it, I would always be wondering if I did get it all or not. I have a BTS and based on his reputation, I won't worry if I did get it all out since he will fix it even though it has been longer than 2 years and the warranty is expired. If you don't have that kind of warranty, the question is whether you are willing to chance that you have cleared everything or not.

Question is, what is your peace of mind worth, assuming you don't have a "forever warranty". More often than not, in my case, when I cheap out, it comes back to bite me in the ass with a vengeance. YMMV
