📚 Vehicle History

Jeep Legacy:

Jeep has a storied history dating back to World War II, known for its ruggedness, off-road capability, and military origins. The Wrangler is the spiritual successor to the iconic Jeep CJ.

Wrangler Tj Introduction:

The TJ Wrangler was introduced for the 1997 model year, replacing the YJ. It marked a return to round headlights and, crucially, adopted coil spring suspension for all four wheels, significantly improving ride comfort and articulation.

Tj Generation Changes:

The TJ generation spanned from 1997 to 2006. Key updates included the introduction of the more powerful 4.0L inline-6 in 1997, improved interiors, a more robust transmission (NV3550 for manual), and the 42RLE automatic transmission later in the generation. The 2005 model year saw minor refinements and option package updates.
