My Troop started shuddering and grinding accelerating from a stop while towing last week. A looked underneath found ATF fluid all over the bottom of the Trooper. I pulled off the road and it would not even move again once I got in some grass.

After putting in the one quart of ATF I had on hand, it would move again. I took 3-4 more quarts to fill it up (filled with the engine running). I put the Sammi on a buddies trailer on the way home, and the Troop has been driving fine since adding the fluid.

What do you think happened? Did the trans just overheat and puke fluid somehow? Is this possible? Or have I likely blown a seal/gasket?

I think the Trooper already has a trans cooler. Should I get a bigger/better one? I was only towing 2500 lbs.
