trans cooler in/out ?

I don't think it matters. It didn't appear to affect mine when I installed it. This tread brings up a question though. I did not by pass the radiator but as I think about it now I probably am defeating the purpose of the cooler. I ran the lines from the tranny to the cooler and from the cooler to the radiator then back to the tranny. My thought now is if I wanted to lower the temp in the tranny and I ran the lines from the cooler to the radiator didn't I just cancel out the effect of the cooler? Wouldn't it be best, if I want to use both, to go to the radiator first then the cooler then back to the tranny? Now that you made me think about it I think I have mine *** backward.

I did the same. Used both the rad and inline cooler? I'm using one of these types. Lets hope someone with more knowledge can answer this. It makes sense to me that more cooling is better but I could be wrong.
