I just got a 06 2500 HD with the 6.0L and a 4L80e. Today I took it to Walterboro and back where it started getting up to 230 degrees while toeing a cargo trailer and about 1000 lbs.

Also, it feels like it is starting to slip because we I start moving from a stop there is a slight hesitation and feels weird while the torque converter unlocks at cruising speed.

The fluid level was good, no leaks and the truck drove well on the test drive.

Any ideas or issues that are known?

I got a great deal so if it needs a rebuild, that's not a major deal to me.
