Updated 6L80/90 Output Shaft Assembly

During model year 2012, Chevrolet and GMC trucks equipped with the 6L80/90 transmission received an updated output-shaft assembly. The previous output-shaft assembly was comprised of a separate output shaft, output carrier ring gear, ring-gear spacer, output carrier internal front gear and snap rings as seen on the left in figures 1 through 3. This required the use of a specific style output transmission speed sensor also shown on the left in figures 4 and 5.
