I may have been a little hasty in my reply. Whereas I do have 2 transmissions for an e9, I see that are seeking a ZF 3HP22.
I have a ZF 3HP20 that I removed from my 1972 3.0 CS in order to swap to a five speed. This was working well before removal. I have everything with this transmission, including the torque convertor, plumbing to the radiator, the radiator itself, the selector switch, etc. These parts (other than the radiator itself) are packaged and ready to ship. (I had a buyer back out of a prior transaction).
The other transmission is a Borg Warner 65. This transmission was acquired along with a large stockpile of parts. I do not know anything about its history.
