I just recently got my truck road legal, and have taken a couple of short (30 min) trips to get the feel of everything. This truck is almost entirely stock, and I plan on keeping it that way. What is the top recommended driving speed to prevent problems with the t-case overheating? Seems like it is comfortable moving at 50-55 on a flat road, but I want to make sure this will not damage anything. I don't plan on taking any super-long trips, but an hour-long drive isn't out of the question. Thanks.
