Context and historical notes
Engine lineup for the JK generation

This kept the Wrangler modernized under the JK platform while maintaining robust off-road performance.
Transmission pairing and trim differences
Across trims—Sport, Sahara, and Rubicon—the 3.8L V6 could be paired with a six-speed manual or a four-speed automatic transmission. The choice generally reflected buyer preference and available options rather than a difference in engine capability.
