3720 Compact Tractor trouble indicator

[swswarthout]

I get a flashing gear wheel with an exclamation point inside and a message saying "Err 06". What ever the error, it seems to limit my highway speed. It may limit other speeds, but generally I am in Lo range and not going fast. Any ideas? I brought it up to the dealer, but no resolution.

I have a 3320 and get the same code (err 06) but I only get it when decelerating after running down the road for fuel in high range. My research has turned up several suggestions that its the speed sensor. They're not expensive, I just haven't had a chance to pick one up to confirm. Might be worth a try. Mine always clears when I shut the tractor down and only reoccurs when I run for fuel again... That's why it's not a priority to me.
