well i said even thought its built its still the weak link, the 4L60E is a matter of when it will break not if.
IMO, it would have been money better spent upgrading to a 4L80E, or the new 6L90E trans, and had improvments in both 60' due to the low 1st gear and HWY MPG due to the extra OD's. But again thats just my $.02. Still a sweet TBSS.
Why has he done all this work and is now selling it?
