TN75 won't move

[twalters]

Looking for some assistance on my 2003 New Holland TN75S MFWD. Bought it used with no manuals. Starts good, but won't move after putting in gear, placing the shuttle in fwd or rev and releasing the clutch.

I have a service light blinking on dash. It's the one that looks like 4 wheels with a book. It blinks fast 4 times, slow 4 times and once, then repeats. I believe it is a code 41, which should be a pressure switch failure.

I started trying to determine which switch it is by unplugging to see if it makes a difference. I found a switch that makes a different light come on, the one with a gear and book and it would blink out a code. Plugged that one back in and it cleared that one.

I think it's one that is right on top of axle on right side that is parallel with axle. Can anybody confirm that may be the switch?

Thanks for any assistance you may have.

Ended up sending in to dealer. Control Module was replaced.
