ATSG Chrysler 46RE 47RE 48RE Transmission Repair Manual | Step-by-Step Diagnosis & Valve Body Details

Comprehensive guidance for the 46RE, 47RE, and 48RE transmissions

The ATSG Transmission Technical Manual for Chrysler 46RE, 47RE, and 48RE family provides a clear, structured path to diagnosing, overhauling, and servicing these four‑speed automatic units. Built to support professional technicians and serious do‑it‑yourself enthusiasts, the manual translates years of experience into practical, task‑based instructions. Expect a detailed look at how these transmissions function as a system, from input gears through the torque converter to final drive, with emphasis on understanding how electronic controls influence operation.

Inside, you’ll find a blend of theory and hands‑on steps that help you identify problems, plan repairs, and verify outcomes with confidence. The publication emphasizes the modern electronic governor and the role of the transmission throttle valve actuator (TTVA) in later models, along with the shift from a cable‑based linkage to electronic control. This context helps you approach common failure points with a methodical mindset rather than guesswork.
