Hopefully, this topic will do several things;

1) Let folks know that the Borg-Warner (now Tremec) T-5Z is a competitive trans, at least for SB applications. It has good gear ratios, is durable, and shifts extremely well.
2) Convince Tremec, or aftermarket suppliers to provide better gearset ratios for the 3550, and TKO.
3) Advise us as to other good trans options: Richmond, Toploader, T-56, etc.
