Compress the 820# spring and install (2) snap rings: 1 round and 1 flat:
After the spring is compressed, the main output shaft bearing can be installed:
Now the assembly is ready to be installed in the main overdrive housing, there is a large snap ring, externally accessed the must be spread to slip over the rear bearing and land in the bearing race's receiver groove.
Prop up the output shaft assembly on something at least 2" tall, this pickle jar works excellent! The lower the housing over the output shaft assembly and spread the snap ring over the bearing:
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!!!
New clutches and steels, ready to be pre-soaked in ATF
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:
Top it off with the wire snap ring/retainer in the groove above the last steel:
