Here I am again. Having trouble with the overdrive again. I have had the transmission out several times in past years and never had a problem before. I suspect that it may be the solenoid, even though I feel it clunk when energized. On the road the red light and relay feel fine, but just is not going into overdrive. I pulled the solenoid off, I am not sure how to energize it from a spare 6 volt battery I have. Can you give me which numbers on the solenoid should be the 6 volts and possibly jumpered. I put my finger in the hole in the overdrive where the plunger rod would go. I can feel the pawl and can (after rotating the drive shaft by hand) go in about a quarter to half an inch. This locks the drive shaft from rotating in one direction. Does this sound at all correct? One of you mentioned that there is a boot in the inside that might restrict the travel of the plunger. I just went ahead and bite the bullet and order another rebuilt solenoid. So if we can't get this ironed out, I should have a spare in a few days. Thanks again.
