hey guys, i need a new tranny in my car and im sizing up possibilities. i have a 91 dx civic 2 door hatch 5 spd. how many splines does my tranny have? are the 89 and up trannies 21 spline or 20? also, will a tranny from a sedan work fine in my hatch without any modifications? will the tranny from a LX sedan civic work? thanks.
