Jeep Wrangler TJ - 4 Cylinder

For years, the Jeep 2.5L inline four-cylinder locomotive returned yeoman service in base model CJ, YJ, and TJs. The scarcely mill, while never a powerhouse, was reliable and produced good low-end torque for its displacement. I had written about a YJ invent back in 1995 that I called, "The Little Engine That Could" because it worked so well. Its difficulty was its bell housing bolt pattern, which matched the old GM 2.8L V-6. The transmissions that mated to this fasten pattern were sub par in every way. Many aren't aware that in 2003 Jeep changed the mechanism in low trim model Wranglers to the PowerTech 2.4L spit-overhead cam, 16-valve four-cylinder that produced about 30-percent more horsepower and torque than the old 2.5L did. The 2.4L had the 4.0L's bell protection bolt pattern, so the new four-cylinder Wranglers shared the same trannys as their 4.0L siblings. That means stronger, punctilious transmissions were available for the four-cylinder TJ.
