Yep! Look above and behind the inching pedal. A 312259 casting # should be the ORC. A C0NN or C3NN-7006-B should be the DDC.

I have run across one 312259 casting in my life that had the DDC installed and appeared to be factory that way.

Anyone have a simple explanation of the difference between the two clutches and how they might differ from the usual clutches in 4 or 5 speed transmissions?

Larry, I got the Case pin for servo #3 and will be attempting the replacement soon. You said you had to cut the pin to size, and I was wondering how one measures the length. Do I drive it in and then trim off the exposed part? Also, do I need to remove the servo to drive out the old and in the new, or can I leave it in place and just remove the interlock cover.

Thanks for your help...

It's not too tough to do with the servo in place. If you got an other than OEM pin it may be long enough that you need to trim it. It's been awhile but I believe I trimmed it to length before driving it in.
