Product Overview

Eaton Fuller K-4223 base-reference Gen 3 heavy-duty XY shifter kit for supported Eaton automated-manual transmissions. Current Eaton parts catalogs distinguish condition-specific service numbers, including K-4223X for a new-exchange heavy-duty XY shifter and remanufactured exchange variants such as K-4223R/K-4223RX. The physical unit and package label must be inspected before changing this listing to a condition-specific SKU.

Application and Service Notes

Confirm the complete automated-transmission model, serial number, ECU calibration, XY-shifter generation, electrical connectors, sensor configuration, exchange condition, core requirements, and the number printed on the physical unit or box before ordering. Do not present a new, remanufactured, or used unit as another condition.

Replacement can require fault-code diagnosis, electrical inspection, XY-shifter calibration, rail-position verification, and Eaton ServiceRanger procedures. Installation must follow the exact transmission service manual and current Eaton service information.

Please confirm the physical label, K-4223X versus K-4223R/RX condition, transmission identification, connectors, calibration requirements, and application before ordering.

Cross-reference numbers, parts catalogs, service manuals, repair manuals, PDF references, and application guides are reference material only and may contain errors, omissions, superseded information, or model-specific differences.
