Rebuilt Borg Warner heavy duty four speed. This transmission was completely taken apart, cleaned, all parts checked and reassembled with new gaskets. The transmission was in excellent condition prior to being taken apart and since it's rebuild has not been used. It has a four ring fine input shaft and large fine spline output shaft. It has an aluminum case with the cast side cover. According to the tech that rebuilt it- it is comparable to the Muncie rock crusher and was a very good transmission. I also have a brand new vintage in the original box Mr.Gasket four speed shifter complete for a bench seat 61-64 Chev or Pontiac for this transmission. $1500 for both but open to reasonable offers. Call me if you need additional info - Norm 1-204-284-2864.
