[TR] A-Type Overdrive Solenoid Question

[William Brewer]

     I was leaving a friend's house and the overdrive quit engaging when the
switch was thrown. This is a new rebuilt trans with about 500 miles on it. 
 
   Tonight I went through and checked all of the connections and oil level.
When the car is in 3rd gear with the key on and you throw the OD switch you
can see the solenoid move sort of weakly. It seems like it would give a good
"clunk". Any ideas?  I am thinking about taking the solenoid off of my spare
trans (which worked) and installing it on this one.
     Any suggestions?
