Anybody know ANYthing about this??

I am sure my automatic transmision is broken, or maybe just the differential, but that I will look into more carefull.

But my thought was, WHEN this automatic trans. would stop working properly, I would convert it to manuel trans. instead of a rebuild. If I should end up doing it, I would make the transplant from another complete car.

Anyone know, maybe in details what I should think about?
