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.

 

I'm pretty sure the SH block has different mounting points, so the base trans won't bolt up. Somebody correct me if I'm wrong.

 

What mounting points are we talking about here. Are you talking about were the half shaft will go.
