Hi I have a case 850k dozer and I’ve had none stop problems with the terminals on the back of the fuse box being loose finally got them all fixed up after months of chasing this and now when you run it the right track seems to stop turning as fast as the left one sometimes and the transmission fault light will come on with codes 4533 and 4311 when I jacked the cab up I noticed 2 of the drive pump solenoids wires were all bear so I fixed them up too kinda makes me think it has something to do with them or maybe still the fuse box thanks in advanced
The 4311 code is left speed sensor out of range. The code 4533 is Joy stick CAN message fault. Do you have a service manual?
