With those you'd be looking at a much more modern transmission, which would be ECU-connected to the engine rather than a standalone unit. Without the right signal inputs from the engine it won't work well if at all. I don't doubt it can be done, but wouldn't be easy.

I'd like to try fitting a column shifter to a defender- seems like it would be the best place to put it, particularly if you had 3 seats in front or a large cubby box.

You can actually do this with the zf4hp22eh autobox out of a disco2. You then need a compushift system so it can control it including tiptronic functions. Best part of 2k from Ashcroft.

Other consideration is the higher gearing, especially in first gear you get with an zf4hp22 auto box normally bolted up to the rover v8. Means going slow off road is more difficult.

Don't forget that the torque converter gives some additional gear reduction- as it slips, torque is multiplied.
