Completely fresh high performance street/mild race 2wd TH400 for a Small/Big block Chevy with 4" slip yoke tailshaft. This is an Auto/Manual shifting (down shifts and holds gear on demand, automatically shifts in "Drive") setup. This is a "HD" case and modified for firm shifts and much more clutch apply pressure. Well built for up to 650hp comfortably, pending vehicle weight and tire size. Nothing hidden, serious build. Serious enquires only, no trades. $2400, or $2000 with good TH400 core.
