Hi my name is Robert.....

So I seen your question and have a source at meritor and got some info for you on this....... Below are the comments.....

That’s an air/electric range shift system. The most likely cause is the neutral switch. It lets the system know that the trans is in neutral so it can shift ranges. The problem was they would stop working when they heated up. If you check them cold they read ok but when they warmed up they were erratic . they are easy to change since they are on the top cover. See circled item on attached picture. That’s the most common cause of what was described, but it could be at least six other things to cause the problem. MM 99106 covers all the trouble shooting for the range shift system on the G series trans. It is available from the Meritor Literature on Demand web site.

Hope this helps.... Robert
