The Jeep Wrangler TJ is the second generation in Jeep’s Wrangler line up of off-road sport utility vehicles, available model years were 1997 through 2006.
The Wrangler TJ came with 3 different engines – the AMC 4.0L I6, AMC 2.5L I4, and the PowerTech 2.4L I4 engine developed by Chrysler. The legendary 4.0L is available through all model years, with the underpowered 2.5L available from 1997 until 2002, with the newer 2.4L engine becoming available between 2003-2006.
In 2004, Jeep introduced a Wranger TJ with a wheelbase that was 10 inches longer, dubbed the Wrangler Unlimited. Unlike newer Wranglers, the Unlimited model did not have 4 doors. It was available until 2006. Jeep enthusiasts call these longer wheelbase Jeeps the Wrangler LJ, an abbreviation for “Long Jeep”.
There was also a multitude of transmissions that came with the second generation Wrangler. Multiple transmissions and engines were paired together throughout the years.
