Fleece is the type of company that when they see an inherent factory design flaw, they fix it. A great example of this the infamous leaking transmission lines on an Allison equipped Duramax. Why would you replace the lines with another set of factory lines when they'll merely leak again?! Instead, FPE designed, tested, and builds highly upgraded lines you can rely on for the life of the truck. Or maybe you want the ability to lock and unlock the torque converter on-the-fly, yep, Fleece figured out how to design a simple to use switch that you can control with the push of a button! When you're ready for a transmission upgrade, look no further than Fleece Performance.
