2006 Jeep Wrangler

The 2006 Jeep Wrangler (TJ generation) is a rugged and iconic off-road vehicle. It’s known for its removable doors and top, solid front and rear axles, and compact size, making it a favorite among off-road enthusiasts. People appreciate its simplicity, capability, and the feeling of open-air freedom it provides. Some common complaints include the relatively cramped interior, especially in the rear, limited cargo space, and the on-road ride quality, which can be harsh compared to modern SUVs. The 2006 Wrangler came with two engine options: a 2.4L inline-4 producing 147 horsepower and 165 lb-ft of torque, and a more popular 4.0L inline-6 producing 190 horsepower and 235 lb-ft of torque. Transmission choices included a 4-speed automatic (42RLE) and a 5-speed manual (NV3550/NSG370).
