Honda Odyssey 2003: I'm replacing a transmission, and a local mechanic will help me to swap it in my garage. I've been told at a local shop, that in order to install remanufactured transmission properly, a computer reprogramming is necessary.
Is that correct statement? What does a process of "reprogramming" involve, what equipment is necessary and why is it needed in the first place? What are the implications if not done?
