Dodge Durango Transfer Case Control Module 68499620AA

This is a replacement transfer case control module (TCCM) for 2021-2025 Dodge Durango 4x4 models and the 2021 Jeep Grand Cherokee and 2022 Grand Cherokee WK. It replaces Mopar 68499620AA and 68499620AB (also sold as P68499620AA and P68499620AB). The listed engine fitment covers the Durango 3.6L V6, 5.7L, 6.2L and 6.4L V8, the 2021 Grand Cherokee 3.0L, 3.6L, 5.7L, 6.2L and 6.4L, and the 2022 Grand Cherokee WK 3.6L. It uses the factory 4-pin and 16-pin connectors and mounts in the original location.

The TCCM reads the 4WD mode selector and commands the transfer case shift motor. When it fails you typically see a Service 4WD message, the transfer case will not change between 4HI, 4LO and neutral, the selector lights flash or stay dark, and the scan tool shows TCCM communication or shift motor circuit codes. Rule out a blown fuse, corroded connector pins and a seized shift motor first, and match the number on your old module label to 68499620AA or 68499620AB before ordering. The earlier 2014-2015, 2016-2018 and 2019-2020 modules use different part numbers and are not interchangeable with this one.

To install, disconnect the battery, unplug the connectors from the old module, unbolt it and bolt the new one in place. Push the connectors in until they latch, reconnect the battery and clear codes. The supplier
it as a direct replacement; if the new module sets a configuration code or the 4WD modes do not respond, run a proxi configuration with a capable scan tool, then test every mode including neutral on level ground.
