McCormick 105 transmission fuse blowing

[czechmate]

i guess a solenoid is going, it should be a 15 amp fuse but have managed to press on a while with a 20 but now blowing a 30. Is there only one place to look or do I have a choice of a few?

When my solinoids went on mine all the fuses were ok, have you checked the solinoids are all working

Is it an extra shift
If so check the flywheel speed sensor

+ 1 for the flywheel speed sensor it's located in the side of the bellhousing just behind the diesel tank. Unplug it and it will work fine just the clutch will be a bit harsher. (Unless it's a restyled cx and it won't drive without it working)
The other option could be the direction sensors on the r/h side of the gear box going in at angles to each other just behind the big pipe the goes down the gearbox, again just unplug them and try it (make sure u know which plugs into which as the plugs the same for each one).

Thank you. Couple of things to try in the morning
I must admit though, I find it hard to imagine the clutch being any harsher than it always has been

It’s 04, does that give any clue as to whether it’s a restyled cx?

Take the 30A fuse out and replace with original size, but you probably already have done that.

Disconnect the ground speed sensor

 

[asm]

If it's an 04 then it will not be a restyled cx

 

[czechmate]

Disconnecting the crank speed sensor did it. Funnily the clutch almost seems a bit better, not worse. Maybe the sensor has been faulty the 5 years I’ve had this tractor
Thank you very much for the pointers.
Any excuse to link this ....

Would this be a similar set up on a McCormick mtx165 with the speed sequencer box? Mine is blowing the transmission fuse occasionally, normally at high speed or revs so usually on the road leaving you stranded at the most inconvenient moment.
