Yep! The '64 and '65 C4 or green dots as they were called are a true three speed but they cannot be shifted manually through the gears. Start out in the "D" position and it will shift through all three gears. Go to
www.mustangcentral.net/tech/c4.html. It is packed with C4 information. And I'll bet this site has a transmission section also. I just changed my three speed manual to a '65 C4 in my '63 Fairlane 500. In the short trip around the block it shifted very well.
Later!
