its the m2b4, 95 JDM H22a LSD transmission. like i mentioned, this one may just need a little TLC, a synchro or two replaced, a complete rebuild, or new transmission. im honestly not sure the extent of the issue. you would have to drive it to determine. 1-5 use to shift like BUTTER, until a week or two ago, its hard to put in fifth gear at higher RPMS, the other gears are fine. if you shift at regular speeds theres no problems. except for the reverse as we know.
