HGi Every1. I have a97 Civic HX auto with 213K miles on it. The tranny is about to go. I'm trying to figure out what options I have. PLease remember this is my daily commuter. If I change the tranny to EX tranny, will I need to replace the ECU? How hard is it to drop a b18B1 auto? will a d17 fit and is it s staight drop? I dont want to get the HX tranny since lots of problems with it and it takes me 0-60 10+ secs while merging into a freeway.
