Everybody wants a T-98 or T-18, but most stock three- and four-speed manual transmissions that found their way behind four- or six-cylinder Jeep powerplants weren’t too bad. At around 2.80:1-3.40:1 the First gear in most is adequate. Some exhibit poor on-road performance like jumping out of gear or grinding between gear changes, but normally that’s from wear-and-tear and no inherent design flaw. The T-90, T-14, T-15, T-150, and T-176 are but a few examples of underrated, but good transmissions. Most are easily rebuilt at home and a simple set of synchros and bearings can toss decades of life back into these cast-iron cases.
