3 speed Overdrive guys need some help!

[NCD1966]

Ok, I had my OD trans in for about a year. played with the OD awhile back trying to get it wired up and working but do to other things going on I never finished it.

I used Gianyveedub wiring diagram below, but it still never worked.

here is a older thread of the od wiring

I then cleaned the solenoid with contact cleaner and a wire brush and then i could hear it click on and off with using the switch.

not really sure what to do; only thing i guess i could do is take the cover off the governor and clean that too.

I really want this to work or it will be a TKO 5 speed going in.

I rather have the 3 speed OD for the stock/vintage factor.
