when i burnt mine out the cluthes where sliping so bad i couldnt make up this like 300yrd hill with my trailor that was about 4000lbs. so i rolled back down the hill and unhooked it then i was just going to drive it to the tranny shop and get someone to pick me up and i made about 15 miles and it was done. all this happened in about 2 hrs. never had any signs of it going out or anything, and one morning it was gone in 2 hrs.......
