i know u can interchange gears and stuff on the d-series trannys, but is that the same for the h23 and h22 trannys? my trans (h23) has a bad 3rd and my friend is gonna give me his old h22 trans, bad 1st gear for parts. between both i am sure i can get one good trans. also i am not to sure if the gears are longer or shorter then what i already have in the car.
