Gehl CTL 85, no high travel speed

I have a 2009 CTL 85 with a Kobota engine. I have just over a 1000 hrs on it. The other day the high range travel quit working. When you turn the key on the idiot light works . I assume that the circuit is good because of that but most likely I am wrong about that. I do believe it might be something easy to fix. Anyone have a problem with theirs ? My dealer is 225 miles away and they aren't too familiar with these machines so that leaves me to figure it out. I use this machine on my ranch...
