What exactly are you calling a transmission lube pump? An 8-speed PS has one trans pump, It supplies pressure to operate the transmission, lube the transmission, & charge the main hyd. pump. When it's worn out, nothing works. And when a tractor gets 10K hrs, it's pretty likely it's worn. Your dealer has not worked on many PS transmissions if they have never replaced one, it's part of the front clutch pack.
