Here is the situation. I have my precious xterra 04 which is manual transmission. My brother lost his left leg in the war and him and I will be sharing the car. I have two options. Get a new car or switch the transmission.

Anyone seen this done? Would there be any problems if possible?

Thanks for all your help.

Anything can be done, but for the cost and complexity of swaping it over, you would be well better suited to sell it and get an A/T. You will save a bunch of money over the swap. It is not just a bolt up operation.

HERE is a document my friend made when he did his auto-to-manual conversion (he did it on a pathfinder - but same exact engine/drivetrain)

It actually is kinda-sorta bolt-in. They make the body the same for both auto and manual and just populate the pedals etc based on what they decide to make it... so if you can find a donor vehicle with all the right brackets, pedals, etc you can just swap it all over

Since you have to change the ECM and add a TCM as well as all of the mechanicals. Tranny cooler, peddle assembly, interior trim componants, it is not really an undertaking for someone with limited knoweledge in this arena.

I still think trading for a similar model with an A/T would be a lot cheaper.

Where do you live?

Someone may want a manual transmission, so you could park them side by side and pull crap from one and shove it in the other.

Just sayin...
