Changing a manual to an auto, how hard is it?

[<atomicL93>]

I've got my donor VL 5 speed, and was thinking about after dropping the running gear into my green vl, to put the old motor and auto back in the donor car and sell it. But what would be involved? especially with wiring up the power button and the drop-gear switch (thats at the accelerator) also the auto ecu. would anything else be involved?

it could be done but not worth the trouble to sell it, IMO
