- Includes Low-range functionality for applications equipped with this selector configuration.

Purpose of the Part

The 3598451C2 is the driver's connection to the automated transmission. When a transmission mode is selected, the control communicates that request electronically to the transmission system instead of using a traditional mechanical shift linkage.

Issue Symptoms / When to Replace

A failing shift selector can cause intermittent or unresponsive shift commands, failure to recognize a selected transmission mode, or communication-related transmission faults. If the transmission will not respond to the selector, power, ground, wiring, J1939 communication, and the transmission control system should also be checked before replacing the unit.

Brand Information

International manufactures commercial trucks, engines, and IC Bus school and commercial buses and supports the electronic and powertrain systems used across those vehicles. This control was designed for International applications using Eaton automated transmission systems and is cataloged specifically as an Eaton UltraShift transmission control.

Installation Notes

Disconnect the negative battery cable before unplugging or installing the electronic shift selector, and make sure the replacement control matches the original transmission and datalink configuration.

A genuine unit can be identified by the factory International label on the module showing P/N 3598451C2
