    I have a NH 8160 that started with codes f45 then flash f43 at the end flash f41 now it will go forward put no reverse. Anyone have this problem and get it fixed?

    Howdy Les, welcome to the tractor forum.

    Here is a translation of your error codes:

    Error Code F41 - Medium/Reverse Range Synchronizer Potentiometer Under Voltage
    Error Code F43 - Low/High Range Synchronizer Potentiometer Under Voltage
    Error Code F45 - Low/High Range Synchronizer Potentiometer Out Of Calibrated Range

    There is a Repair Manual on CD for an NH 8160 on ebay for $19. It should address repairs for error codes. EBay item number: 122437223113

    From what I can find on the internet, you likely have a potentiometer gone bad on the right hand side of the transmission (there are 2 potentiometers there). You can swap them and check results.

    You can also try recalibrating the transmission. There is a procedure in the manual. If that doesn't fix it, maybe it has a bad potentiometer, but sometimes it just needs recalibration.

    The recalibration procedure for the transmission is in the manual. I found the attached pages on the justanswer.com website for a NH 8360 tractor. If you have problems with recalibration, they may be able to help you.
