For those that do not have a spare intermediate shaft to cut down, this tool (6227-2) can be used to align the planetary and sprag while assembling the overdrive section in a 46RH, 46RE, 47RH, 47RE or 48RE Dodge automatic transmission.  Unlike an intermediate shaft, the splines at the tip of this tool are tapered/thinned to help self-align on insertion.

Color may vary.  The steel alignment tool shown here is for visual comparison only, it is not included.

This tool is not the same as the Chinese copycat versions you will find across eBay - it is the original, USA designed and made
