Dodge Ram 68RFE – ATSG (Automatic Transmission Service Group)
Dodge Ram 68RFE – ATSG (Automatic Transmission Service Group) PDF. Beginning at the start of production for the 2006 model year Chrysler Corporation has introduced a new version of the 5/45RFE transmission and is found in Dodge Ram trucks. The new 68RFE designation tells us that this new unit has 6 forward speeds, a relative torque rating of 8, is for Rear drive vehicles and is Fully Electronic controlled. The 68RFE transmission is a sophisticated, multi-range, electronically controlled transmission which combines optimized gear ratios for responsive performance, improved efficiency features, and low NVH (Noise, Vibration, Harshness). Other features include driver adaptive shifting and three, 6 pinion, planetary gear sets to provide wide ratio capability with precise ratio steps for optimum drivability. There have been several engineering changes in the geartrain to improve durability and reliability.
The primary mechanical components consist of the following:
- Larger Bell Housing, different bolt pattern and a cutout to accommodate diesel applications.
- Three multiple disc driving clutch packs.
- Three multiple disc brake clutch packs.
- Three 6 pinion planetary gear sets (Totally New Design).
- Dual stage hydraulic oil pump.
- Valve Body and TRS/Solenoid pack.
