I was wondering if there was any difference between the USDM ITR transmission and JDM ITR transmission? I bought mynew ITR tranny last week and installed it, and the guy I bought it from said that since its the JDM version, it comes with a different final drive gear, is this true? Im just wondering, plus I have never driven a type R before, so I wouldnt be able to tell any difference.... also, is there any special type of tranny fluid I should use since I now have LSD?
