Well, it seems my 4+3 on my 87 has finally gone to that big scrap pile in the recycle factory. My guy says it'd be better and cheaper to just replace the tranny; half the gears are worn down, the synchros need replacing, etc. He says I should replace it with a 6spd because it's newer and will give me better performance. My question is, 4+3 or 6? I suppose the 6 is technically superior, but the 4+3 is part of an 87, isn't it? and i'm not too sure about performance really being an issue; I;ve seen a 4+3 beat a 96 6spd in the 1/4 mi. so what do u guys think?
