Next install the overdrive brake clutches, stock 47re has (5), stock 48re has (6), this one had been converted back to (5) when the Dodge dealer rebuilt it several years ago.

Stepped reaction plate, this is stock on 48re's but purchased in the aftermarket for this build to revert back to (6) clutch overdrive setup:

Palm sander to roughen up the face of the plates for more bite, everything wears smooth after a few thousand miles but those first thousand miles feel nice and aggressive to give the customer confidence in their new tranny!!!

Install lower snap ring and waved snap ring if you want a little softer overdrive engagement, otherwise remove the waved snap ring and just use (1) regular.
Install stepped reaction plate and add clutches and steels:
