B7510 Jerky In High Range

[Farmall45b]

I am posting this for a friend that owns a B7510HSD tractor. When operating the tractor in high range there is a jerk when accelerating. What will happen is you will be moving very slowly and then step on the pedal just a bit more and there will be a pretty good jerk. This problem began while the tractor was still under warranty. The dealer told him that it was normal and that all the tractors did this. They said that there was nothing that could be done to repair this condition. Was some time has gone by and the tractor is now out of warranty and the problem has gotten worse. The dealer service manager said that to check all the linkage for. All linkage was taken apart and found to be free and lubed and put back together to no avail. The service manager says that the problem is inside the transmission and that they can repair it. My friend is kind of mad because when under warranty they said there was no repair that the problem was normal and now out of warranty the problem is worse and they say that yes indeed they can fix it. The tractor has about 150 hours on is and has had regular fluid and filter maintenance with Kubota parts.

Has anyone else had this problem, or been able to repair this?

He is going to try and get the dealer to cover the repairs. It would be helpful to know a little bit about this problem before talking to the dealer again. If the dealer will not fix it under warranty, he is going to try and fix it himself if possible. Has anyone else had this problem, and if so what was done to repair it?
