Transmissions

Although we are not doing full units in-house at this time - previously Goerend complete transmissions came with the following possible upgrades:  

For 47RE transmissions: 

  • 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
  • The Trans case is drilled for extra lube to the rear one way roller clutch
  • 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
  • The overdrive planet is a 5 pinion
  • The overdrive direct clutch has 10 double sided or 23 single sided plates
  • The overdrive brake clutch is the 5 plate design

 

For 48RE transmissions:

  • 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)

  • 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
  • The Trans case is drilled for extra lube to the rear one way roller clutch
  • The intermediate shaft is the dual lube hold design shaft
  • 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
  • The overdrive planet is a 6 pinion. 
  • The overdrive direct clutch has 10 double sided or 23 single sided plates. 
  • The overdrive brake clutch is the 5 plate design. 



All parts are inspected, assembled and installed in the transmission. Once together, the transmission is then dynamometer tested. While testing on our dynamometer: 

  • All hydraulic pressures are checked. 
  • Cooler flow and pressure is checked. 
  • The transmission is checked for excessive noise in all gears. 
  • The park gear is checked. 
  • The neutral safety switch checked.


Once this testing is complete the fluid is drained and inspected. The transmission pan is then removed and inspected for any unusual debris and then the transmission is dynamometer tested again, checked for leaks and all electrical components are tested under load. If the core has a cracked case or overdrive housing or has a broken input shaft, a fee will be deducted. 

When these transmissions or components are being used in any type of off-road events including, but not limited to sled pulling, especially where the engine RPM can exceed the factory governed RPM, we will not be held liable for any personal injury or property damage. The customer is responsible for insuring that the vehicle has the proper safety related items in place for safe operation. In these cases, the transmission and torque converter should be shielded with appropriate shielding.

Transmissions are shipped at Class 85 NMFC #19940
