So I drop my ctr swap that I just got from H-Motors online into my 99 hatch yesterday hooked everything up fired it up runs good. My problem is I can't drive it because it makes horrible banging popping noise from the tranny. It only occurs when trying to turn (the axles are fine). Obviously the diff has problems. My question is has any one else had a similar problem? Also is it possible the tranny has an aftermarket diff that is causing this? Any help/advice would be welcome. Thanks
