There is a forward synchro cone for direct drive through the auxiliary section (high range), and a rearward synchro cone for low range. The forward synchro cone in the auxiliary section is worn, or...there is a possibility that the air pressure to the valve and the yoke bar might be low, or maybe the O-rings for the yoke bar are worn.
Before you remove the auxiliary section, look on the side of the transmission for a tag with numbers on it. If it's an Eaton, then there should be a number beginning with R.
It may be something like RTO14709. I think the "T" means twin countershaft. If it's not an overdrive transmission, it won't have the "O." The first two numbers have to do with the torque rating, the third number has to do with the gearing, and the last two are the number of speeds.
Here is Road Ranger's number 800 826-4357 I think you need option #3, then #1
Here is a Road Ranger website for service manuals.

The Road Ranger techs are good. They know their stuff and they're helpful. Before you dive into the job, I would advise talking to them. They will guide you better than I could.
I downloaded service manuals and parts manuals for free, but for some reason, I can't find the free downloads now. I don't know if it's my computer or a change at Road Ranger.
I removed and repaired the auxiliary section on my 15 speed, RTO14715, and I could probably help you. One thing I would do before pulling out the auxiliary section is to find out something about the air pressure, air valves, and O-rings. You might could save yourself a lot of work.
