If not in a rush I may be swapping out a 260 auto in a month or two that was apparently 'rebuilt' with 20,000 km on it.
The guy I bought it off was a bit dodgy, though the gearbox seemed fine when I drove it ;-)
I am sure you know the gearbox in question here, if I go ahead with the swap i will let you know and you can have it back. Only limited driving so far, however it drove really well.
