FWIW, there's really no reason you can't go for a test ride with the tunnel
out.  I've done it lots of times, no worse than riding a motorcycle.  Be a
little careful about where you put your right hand, though.

If you can duplicate the problem that way, then you can see an important
piece of information : when the OD fails to engage, is the plunger up or
down ?  If it's down, then most likely the problem is electrical in nature;
possibly the contact points inside the solenoid itself.
