In 2000, Jeep began using the NV3550 in Wrangler TJs and Cherokees. It has become the medium duty 5 speed of choice. It is plenty strong for a medium size small block V8. All five gears are fully synchronized and shift very smoothly and easily.
This unit is conservatively rated by New Venture Gear at 300 ft/lbs torque handling capacity. The NV3500, used by GM and Dodge with V8 engines, is an earlier version of the same transmission.
Oblong pattern, with 9 metric bolts. It shares the same bolt pattern with the Japanese made AX15 as used in Wranglers 1989-1999.

The fine print: As for “is it 100% Bolt-in”, yes, all the components should bolt together fine. However, I would never consider or assume any installation of a transmission that did not come in the vehicle was going to be 100% bolt in: 1. Might work out that way. 2. Most cases have a few issues you will need to figure out on the fly. 3. Occasionally there is some issue we did not anticipate that turns out to be a hassle. That is rare. In any event, our customer service is always available to help you resolve whatever issues may arise in your conversion. Our Tech Support is generally quite a bit more knowledgeable than the average Joe you get on the line!
