The torque limitor will slip some times and then take ahold. They get a film of oil on them and when they slip it will burn the oil off and go again. It is possible that it is getting close for a new torque liminator. MACK

If you reallly want to know if it's the torque limiter,don't apply the brakes a little,stand on them at wide open throttle in 4th or 5th gear,low range side.It should kill the engine,or at least pull it down to the point that you know it is going to hold under a heavy load.

I would say you are ok after it slipped. That is the way it happens. MACK

Your rear main seal is probably leaking. That and the torque converter slipping will get worse with time. When the busy season is over, you may want to split the tractor and fix the seal. That would also be a good time to put the "pie pan" cover over the torque converter that I convinced people to add to the tractor when I gave up on Harvey building engines that wouldn't leak oil out of the rear main.
