Should I just drop it to D3, and let her spin? I've read that the 6.0 likes to run at a higher RPM.
Thanks for any input.
The short answer is yes. You'll save the cost of replacing a transmission too. With the older 4 speeds never, ever, tow in 4th gear. As you've already learned it will constantly hunt between 3rd and 4th. That hunting generates heat. Keep it in 3rd and you're torque converter will lock and keep the trans temps even. You see temps go a up a little when towing in the wind or up hill but it will generally stay locked.
Also try running a little slower, 62/63. That'll knock a couple of thousand off the RPMs too. This is also the speed that most of us have found is the "sweet spot" when towing.
