If the rest of the trans is still good.Then Pete Burton is right on the money saying the clutch wear was probably due to a leaking seal on the servo piston.That's an internal seal by the way.It's not the front or rear trans seal.I don't know the exact specs on you'r model trans.Or if the servo piston seal is internal or external access behind a cover.But it would be a good idea to make sure it was one of the seals replaced.An external leak and low fluid would cause wear in all of the trans parts.
