Ok I just bought a 99 Prelude SH. The Tranny is shot there is no fourth gear, I have a base model h22 tranny in my basement. To take out the ATTS tranny and switch to a base model tranny. What do I need to do get a base model p5p ecu and base model wire harness. I am lost on this, or can I just swap the tranny over and its all good. Please if anyone can give me some insight on this. That would be great.
