Question
I have a code p32 that comes up on the display and the tractor would drop out of gear when driving. I was driving it and it started jumping between gears. then it just stopped moving now it shows cp on the shifter disply. The tractor is a case MXM 175 with 18/6 transmission. Ihave checked all the connections on the transmission. I don' now what to do could you help me

Answer
  I finally had access to a service manual today and looked up code P32.  Unfortunately, that code has nothing to do with your transmission problem.  P32 means the steering angle sensor is out of range.  This would only affect the automatic mode of operation for the diff lock and 4 wheel drive.  CP means clutch pedal and it is telling you that you need to cycle the pedal before it will allow the tractor to move.  This is a safety feature so that you can't shift the shuttle lever out of neutral into forward or reverse without using the clutch pedal the first time after getting in the seat.  If you did use the clutch pedal and it still shows CP, then there could be something wrong with the clutch pedal potentiometer or bottom of clutch switch.  Or possibly the operator presence switch in the seat is faulty and the tractor thinks you got out of the seat.
