if any of you has done a 1kzte 2nd generation replace the auto-box (4 gears) for an auto-box of 5 gears?
if yes, what box? and any difficulties?

The nearest 5 speed Auto box I can think of is the A650E.

It would be an utter ball ache to fit, with lots of custom work - especially on the transfer box end.

I have a A650E at home, it came with my Lexus, It wasn't worth it then, when it already mated to the engine, with the correct management to run it, its certainly not worth it as a standalone upgrade!
