Yall Seen This Yet?

Since with a junkyard transmission you'd still need to get SST's (Keisler's) bellhousing, flexplate, tailshaft housing and output shaft (for speedometer drive capability), linkage, and electronic shift controllers anyway; you'd most likely be close to SST's cost once you figure in that it's a fresh transmission (with a warranty) with your choice of convertor stall.
Maybe, but we still don’t know how much this kit cost. It could be $7K+ with todays prices. It’s all speculation until then.
