I agree. I had to keep an eye on the pyrometer on mine when towing. It would tow anything, but if I wasn't watchful it would get into the hot zone.

Swapping out the stock converter for an aftermarket diesel converter is about the best mod you can make on these trucks. And if you dont go crazy with the power mods the stock trans holds up just fine.

I had a well built trans installed in mine just because of the power range I was working with.
