Tranny compatibility
Hey guys my 03 civic hx manual tranny is trashed and was wondering if I could use tranny from another model civic within 01-05? I was thinking of picking up an ex tranny for cheap and i understand the gear ratios are different and the ex tranny has shorter gears which doesnt bug me just means slightly lower mpg. Any input would appreciated.

Re: Tranny compatibility
The only thing different between the HX and EX tranny is gearing. And there's nothing to plug in being a manual. With the shorter gears the VTEC would engage faster but, the HX engine engages at a lower RPM anyways. See here for differences in the D17A2 (EX) and the HX (D17A6) engines: http://en.wikipedia.org/wiki/Honda_D_engine I would think you would be fine with the EX tranny
