Hello everyone! I just purchased a 2008 R51 4x4 S. It has 90K miles and runs great. Since I bought it I have been reading about the common transmission problems with this generation Pathy, so I am aware of the option to bypass the radiator cooler. I did purchase the truck with a full warranty. That being said, I am a little reluctant to bypass the radiator cooler and just run the factory external cooler because I don't want to void the warranty the truck came with. So, my question is... Is there an aftermarket radiator I can switch the factory one with to remedy future failure from the factory radiator leaking? Or do I just let it go and if it fails just repair it under warranty, because it would definitely be covered. I have checked the tranny fluid and coolant often, and so far have not found any signs of the 2 fluids mixing. The truck runs awesome, shifts great, and has plenty of power, so I don't really want to let it fail. I just want to get everyone else's input. Thanks in advance, and i'll have pics up as soon as I can take some nice ones out in the dirt or snow.
