O/D issues

["Bruce Moxon" <bamxn@triad.rr.com>]

My "A" type O/D had begun to have a mind of its own as to when it would
engage. So I cleaned out the filter and it worked like a champ for about a
month then did not work at all. Thinking it was the solenoid, replaced it.
When I turn the ignition switch on, put it in 3rd or 4th gear, nothing
happens. If I put in 2nd gear, the solenoid will actuate. Thinking it might be
a bad switch on the gearbox cover, I switched them but get the same results.
Any suggestions?
