towing capacity for a GMC 2500 sierra
The towin capacity for my 2007 GMC 2500 (gas V8) is 10k#. I'll be hauling a
gooseneck horse trailer - what are your max recommendations for hauling
weight that won't hurt the transmission?
Keep the weight under the max and you should be good to go. It won't hurt to change the transmission fluid first. If you will be doing a lot of towing up steep grades then you might want to upgrade the transmission fluid pan and install a transmission fluid temperature gauge.
