My 950H won't go into reverse any thoughts?
Please post a Serial Number and also describe exactly what happened to the machine leading up to this point. e.g. were you losing reverse occasionally, was the transmission at one time slipping in reverse then gave up completely, etc, etc. Also list whatever you have done/checked so far. That saves asking too many questions.
It was working yesterday forward and reverse got in it to day forward works but reverse doesn't.
Checking the forward and reverse selector but not sure how to test it
On the face of it that sounds electrical. Post a Serial Number and I can look up the appropriate electrical schematic.
