Eastern Kansas
2014 340 magnum with a cvt. Popped up that the transmission lube filter was blocked, then would go away. Transmission pressure was 318-320, somewhere in there. Ran for couple hours and went to move down the road and it threw it into neutral. Can’t get it to move. When you shift into forward or reverse and push the handle to go it will kick it back into neutral. Tried to calibrate the transmission and it just says “hsu unstable”. Increased the transmission pressure to 348 at 1500 rpm. It has new filters on it now. The pressure was still reading the same after the filter change until I increased it. Not sure what to look at from here. Throws fault codes 2840 & 2843 and nothing else.

Thanks
