A Goerend complete transmission comes with the following upgrades:

* New triple-disc torque converter
* Upgraded valve body.
* 4140 steel 1-2 lever.
* New Dodge input shaft and hub (non-billet).
* All bearings are replaced with new Torrington bearings, including the output shaft roller bearing.
* New overdrive sun gear is installed with the late style bushings (this will force lube oil out to the gear teeth).
* New snap rings are installed in the front & overdrive clutch.
* New seals & gaskets are installed using the updated versions.
* New release spring in the rear clutch.
* We install a steel front planet gear in all Diesel and V-10 transmissions. Early models (1995 and earlier) may have come with an aluminum front planet.

For 48RE transmissions:

* The front planet is a 6 pinion steel planet and the rear planet is also a 6 pinion steel planet.
* The intermediate shaft is the dual lube hold design shaft.
* The overdrive planet gear is the late design 15* angle with the large lube slots cut into the carrier frame to allow more lube oil to get to the planet pins.

Also, on 48RE transmissions:
* The overdrive planet is a 6 pinion. The overdrive direct clutch is the 10 plate design, including the larger apply spring.
* The overdrive direct clutch has 23 single sided plates.
* The overdrive clutch is the 5 plate design.
* The Trans case is drilled for extra lube to the rear one way roller clutch.
