Interesting. Like you said there are tons of information regarding the "ideal temps". I've been wondering about what temps are actually safe for the 4r100. I know they have the trans behind diesels, and they are pulling heavier loads then we'll ever pull with our Expys. I know the diesel versions have a "cooler bypass line" that commonly have issues with the bypass valve, which causes high temps...and frequently get deleted. I haven't been under mine recently to see if it has the bypass cooler line. If it does, I'll probably delete it, and see if that helps any with temps. In the mean time, I think I'm going to order another Hayden. Due to several arm surgeries, I haven't been doing a lot this summer, so I haven't been pulling what I normally do. I need this thing to last me for a while, so I need to take care of her.
