Southeastern Tipton County, Indiana | 125codeman - 5/19/2022 14:52 Hello to all, I have a caseIH STX 480 I am having some trouble with, The tractor starts and runs fine but when you go to put it in gear it says transmission FAULT. Every once in awhile it will go I to hear and operate as its suppose to. I have replaced the FNRP switch with harness as well as the park brake pressure sensor and park brake solenoid with no success. I am getting two codes . Number 51 and 59. Any help or suggestions would be greatly appreciated. Thank you in advance
51 is in park when forward or reverse is selected.
The not park signal activates the park release relay.
The signal from the park sensor sends a response to the transmission controller.
59 is FNRP in illogical position, usually set if the lever is held in the up position a bit too long.
