Any one outthere running a FS-2500 by-pass filter on thier transmissions, saw it on thier website and it seems like a good idea, just wondering if anyone is running one.

Do a Search that would be a no go.

I think I saw an ad in the new Diesel Power mag.

Marc (http://www.dieselplace.com/forum/member.php?u=7217)has the harvard unit on his tranny and engine. You might want to contact him, he is very helpful.

Yes, it can be done but I'm just in the process of returning mine. FS was trying to come up with a PLUG and PLAY adapter for the return line of the tranny cooler. I didn't want to cut any factory lines and put a "T" in. I was afraid dealer would not warranty it if they saw the factory line cut if there was ever an issue. I bought two of them and will be returning one. Lots of people say it's a waste but it's been proven in the commercial side of things.
I just don't want to push the envelope with the Warranty.
