I have been doing a lot of towing lately so I hope anyone who figures out a good mod will post up! The lower gears in my VX help tremendously but the tranny could definitely use a cooler. I just towed 2000 lbs of stuff after all! And BTW, running a quality synthetic ATF should help keep things cool as well - just my opinion, I have no proof. Speaking of tranny mods though... Tone offers that in-line filter for the tranny. Would it be possible to run a cooler off of that somehow?
