Blue smoke while towing...

Like the title says, I was pulling out gooseneck today and I had 7,200 pounds on. I was coming up from a bottom and I while coasting down the hill my TC locked up and when I went to get back into the trottle it started jerking really bad like it always does with the gooseneck on and the TC locked up. So I decided to shift down into 3rd and when I did the jerking stopped and I looked in my mirror and it wasnt a solid cloud of blue smoke but a pretty good amount. Just wondering what it was from and if anyone knows a good way to get the truck from stopping to jerk with the TC locked up?

I am running on the 150 hp tune from Spartan and I dont know if traction bars would help with the jerking while towing but I need to figure something out because thats when the truck does most of the winter months.

Thanks for the help in advance guys.

Yes the bars would help with the bucking issue.
Blue smoke typically means your burning oil. Ck your oil level and go from there.

Any DTC's?

No not reading any codes, thats the first thing that I checked when I see it and nothing came up.
