The reverse finally went out in my '81 300TD estate. I could not for the life of me find another 1981 electric speedo trans in the Chicago area. So I got one out of a '84 300 four door sedan. Got a new cable, flex discs, and all that. It went smooth as glass doing the R&R.

However the overdrive dose not engage. I would assume that there was a trigger wire off the electric speedometer that switched it on and off.

Anyone have any ideas or experience with this?

It's great to have reverse again but o/d would be wonderful on the expressway.

Thanks guys!
