Peterbilt broke my truck, how much should they be responsible for?

They had to take the Yoke off to fix the speed sensor problem and the Yoke was rusted on. Nothing to do with the clutch. The clutch job is finished and already paid for.

 

I heard back from Peterbuilt. The service advisor at talk to the service manager and came up with a great deal for me. They will take care of all parts all labor except for a remove and replace one transmission which he says is 8 hours. I told him I'm in my way in and have the service manager there.
New question should I pay the bill to get my truck back to get back to work. And then go ahead and sue them in small claims court. Or do I give up my right to sue them if I pay the bill. I understand we have a lot of CB lawyers out here

 

Went in and talked to the service manager. Guess I wasn't given all the information. During the clutch replacement was told that the Yoke had a stripped bolt hole. They attempted to remove the Yoke by heating it up. They guessed they were able to back it off a couple thousands and that's what loosened up the toner ring. That is why my speedometer didn't work properly after I picked it up. They ended up repairing the stripped-out hole instead of replacing the yoke.
With that being said I figured I'd be responsible for the toner ring being it was part of the clutch. I'm paying four hours of Labor and that's it.
