According to the service tech, it seems Deere, from time to time, changes the recommended operating range of the electronic/computer-run transmission functions in the eHydros. Apparently one of the functions in mine was set at a limit of its prescribed operating range. The current service manuals have not been amended to illustrate the latest settings. I was at the shop this morning and the replacement 4410 was parked next to mine ready for the loader and backhoe to be switched over. I opted to keep the original one because the tech had me believe the problem was solved by adjustment that he completed. Also, Deere has extended my warranty by twelve months at no additional charge. I still have a leak-down problem in the backhoe. however, so the tech has ordered a replacement valve that he will install in one day as soon as it comes in. That will be an opportunity for me to have corrected any bugs that might come about in the mean time. Fingers crossed! /forums/images/graemlins/grin.gif
