Just last night I was backing in a 3K trailer up a hill and my transmission was giving me fits. The truck would be jerky and then ease off. With all said and done backing the trailer up and around I noticed an electrical burning smell that was stronger from outside front of the cab. I have had the problem of jerking with and without a load in both reverse and starting off in first, second, and even third (it has not been constant though) since a transmission shop replaced my clutch pack and throughout bearing.

Any ideas?

Thanks ahead of time.

Sounds like you smoked the clutch.
