Towing and transmission issue

[Jackpine]

I wonder if your transmission is "slipping" under load and with the fluid hot? Is it still under warranty? If so, set it back to stock, remove the Gryphon and take it to your dealer. I think they may need to "look" at it.

I think I'd do this even if the truck is out of warranty.

This doesn't sound like something I'd like to see continue, because it could be an early sign of damage.

You should NOT be having problems pulling a 5000# load. You'll certainly know it's there, but the truck was designed to do this task.
