turtle/rabbit switch issues

My TC40DA doesn't want to shift from low to high speed range with the "turtle-rabbit" switch. Both the main switch and the one on the loader lever seem to work in that either will make the other light switch from one to the other and I can hear the relays clicking each time. Could it be the solenoid switch and if so, where is it located and how can I trouble shoot it?

Any advice would be greatly appreciated!

Still haven't resolved the speed switch issue on my TC40DA. I read somewhere, on a blog, that the solenoid switch going into the HST transmission can stick and a "fix" might be to remove it and either replace it, or make sure it is moving in and out when activated. Has anyone had any experience with this? I'd appreciate any and all advice.
Thank you so much.

Has anyone had any experience with this?

Apparently not, because most on here would answer if they had experience, otherwise don't say anything.
Sorry, I don't have a clue either.
