Shuddering while towing on hills

Recently while towing my jeep ~6500-7000lbs with trailer, anytime I go up a hill I get a shuddering or shaking for maybe 2-4 seconds then it goes away, it only happens if I slow way down before hitting the hill and I'm basically pulling from a stop on a hill, no matter how little or much gas I use, it still does the same thing.

Any ideas?

It might be the T\C slipping? I am guessing you have an auto. Where does it feel like the vibration is coming from. Any sounds?

tcc chatter, sounds like you are running over the safety ribs they cut into the edge of freeways and school zones

yes, its an auto, it feels like its coming from the trans or back from there, I was thinking either trans/transfer case/carrier bearing but can't put my foot on it

thats exactly what it feels like but its only for the first few seconds when pulling a hill, after that its fine. Does that sounds like a torque converter?

yes , it's usually only for a few seconds. Hardly ever constant.

My truck was doing the same thing the other day while pulling about 12,000 pounds...and I have a manual. I was thinking clutch slippage but the rpms were not fluctuating
