ATSG 46RE/47RE/48RE Transmission Repair Manual — Shop-Tested Diagnostics & Rebuild Guide

ATSG 46RE 47RE 48RE Transmission Repair Manual is a comprehensive step-by-step technical guide for diagnosing, overhauling, and repairing Chrysler 46RE/47RE/48RE automatic transmissions.

This manual compiles professional, shop-tested procedures and illustrations to guide technicians and experienced DIYers through every stage of service on the 46RE, 47RE, and 48RE transmission family. It covers models used across multiple Chrysler vehicles and engine sizes, including diesel applications, and addresses both 2WD and 4WD configurations. The content explains mechanical assemblies, electronic controls, and the specific parts and sequences unique to these four-speed automatic transmissions.

How does this manual help me diagnose shifting or pressure problems?

The manual presents clear diagnostic flowcharts and troubleshooting sequences to isolate faults in governor pressure, valve body operation, solenoids, and the TTVA system. Stepwise checks for electrical inputs, hydraulic pressures, and mechanical wear help you determine whether a problem is electrical, hydraulic, or internal-mechanical.

• Governor pressure tests and acceptable ranges for each gear
• Valve body maps and flow diagrams for pinpointing internal leaks
• Electrical wiring diagrams and connector locations for solenoids and sensors
• Common symptom-to-cause pairings (e.g., slipping, harsh shifts, no engagement)

What repair and overhaul procedures are included for the 46RE/47RE/48RE?

ATSG provides detailed disassembly and reassembly sequences with torque specs, tool recommendations, and parts identification. The manual outlines clutch, band, and planetary procedures, as well as converter and overdrive section service, so you can perform partial repairs or full rebuilds systematically.

• Step-by-step removal and installation instructions for the valve body and governor components
• Clutch pack and band replacement with correct clearances and measurements
• Overdrive unit teardown and rebuild guidance including OD/direct clutch servicing
• Torque specs, shim tables, and end-play procedures for accurate reassembly

Which electronic and control systems does the manual explain?

The manual covers the electronically controlled systems fitted to later models, including the Transmission Throttle Valve Actuator (TTVA), push-in Range Sensor, and electronic governor interface. Wiring harness layouts, connector pinouts, and solenoid operation descriptions allow you to test or replace electrical components confidently.

• Wiring diagrams and harness routing for 2002+ transmissions
• TTVA operation and replacement steps for diesel-equipped Dodge trucks
• Solenoid identification, testing methods, and expected resistance values
• Connector and sensor locations for quick access during diagnostics
