I would recommend checking pressures and the only test ports that are suppose to have pressure in 15th gear are C1,C2,BHi & B4. I would suspect that Clo may be getting some pressure and it isn't suppose to or possibly has some warped disc's.

It runs fine in 15th gear until you throttle down and then hit the throttle again. Loses about 3 mph and the engine seems to labor and in about 3-5 minutes the hyd oil temp light comes on along with the ? and eventually the stop alarm.

It"s possible that low trans pressure is causing the alarm to go off,low pressure can cause a slow shift letting one clutch stay on a bit longer or one "not" engaging quick enough. warm it up and do some pressure checks to see what kind of trans pressure you have,,another possibility is a clutch can be warped and dragging too...B&D is right deal with it now and the cost may be will only get worse....

Don't keep operating the tractor in any gear. A moderate priced repair will be very expensive.
