This comprehensive PDF file contains the complete Automatic Transmission Service Group (ATSG) technical repair manual for the Dodge/Chrysler 68RFE transmission. Introduced in 2007 for Dodge Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins Turbo Diesel engine, the 68RFE is a heavy-duty, fully electronically controlled 6-speed automatic. This ATSG manual is the gold standard in the transmission rebuilding industry, providing the exhaustive, professional-grade technical data required to correctly diagnose faults, perform complete overhauls, and ensure the rebuilt transmission can handle massive diesel torque.
The workshop manual covers the following key systems in deep technical detail:
- Component Teardown and Inspection: Step-by-step procedures for completely disassembling the transmission. It provides detailed instructions on how to inspect the three planetary gear sets, the dual-stage hydraulic oil pump, and the clutch packs for wear or damage.
- Valve Body and Solenoid Pack (TRS): Highly detailed guides for the “brain” of the transmission. It covers the complete disassembly and reassembly of the valve body, including the exact locations and specifications for all springs, valves, and checkballs. It also includes testing procedures for the Transmission Range Sensor (TRS)/Solenoid pack.
- Clearances and Specifications: The critical measurements necessary for a successful rebuild. The manual lists all factory clutch clearance specifications, thrust washer and Torrington bearing locations, endplay check procedures, and precise torque specifications for all fasteners.
- Electrical Diagnostics: Technical data for troubleshooting the electronic controls. It includes information on diagnosing trouble codes (DTCs) related to the transmission, solenoid specifications, and electrical voltage and OHMS testing procedures.
- Exploded Views: Comprehensive diagrams illustrating the exact order of assembly for every component, ensuring correct reinstallation during the rebuild process.
Whether you need the precise clutch pack clearance measurements, a diagram showing the exact location of the valve body checkballs, or the OHMS testing specifications for the solenoid pack, this ATSG manual is a vital resource for expertly rebuilding the Dodge 68RFE transmission.
