Bummer!!!! I whine and bitch about computer glitches with our machine causing codes. But it's not mechanically failed me.
Is Warranty taking care of your repair?
I'm at 1,300 hrs. I change the engine oil at 250hrs. I never have to add any between changes.
I'd be paranoid about what the engine oil is doing to the trans???? JD transmissions seem to be a bit weak and vulnerable. Hope it goes well.
A neighboring Township has a 672D. It's 15 years old or so. Only has 2,800 hrs on it. 1st/2nd gear trans clutch failed. JD replaced the trans with a new one rather than trying to rebuild theirs. Weren't any in warehouse stock so they pulled one off the factory assembly line. Cost them $35,000 by the time they got it back.....
