Your torque limiter needs to be replaced. Needs to be split but not the worst thing to happen....

Unfortunately, a torque limiter doesn't fix itself. This post is quite confusing and needs questions answered accurately to come up with a solution to the problem. You said you changed all the filters??????? Exactly, which filters did you change and did the problem exist before you changed the filters. Where are you checking your oil levels?? There are TWO PLACES for oil on an 8030.

Thanks for responding. oil levels in both chambers are checked regularly.

problem started before all three filters were replaced.

And how does the tractor act this morning?? Does your 1800 RPM transmission light work??

I think I'd add 2 gallons of oil down the tube with the long dipstick in it just to see what happens.
