These products are certainly interesting for me since I tow a lot.
Although I haven't overheated the tranny while towing (maybe saw ~205f max while towing), I'm usually the preventive type. I especially don't like the thermal bypass which doesn't let fluid go to the cooler until it reaches a certain temp. Mine seems to hang around ~195f during normal driving.
Both aren't cheap $351 and $126USD respectively + shipping. PPE ships to Canada for $44 but Demonworks for the cooler doesn't but ships for free to a US address. PPE will ship to a US address for $14.
My biggest concern would be if I ever do have a failure that needs warranty work, they would refuse it because of these mods. Is there a precedent for this type of claim?
