NV3550 General Information:
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.

Shifters
Jeep Factory shifters:
Early style: Square shift stub: Shift handle fits on and is located with a set screw
Late Style: Round shift stub with a female thread.
There is also a type where the stub comes up and is flattened, and has two holes drilled though it around 3/8 dia. A shift handle is mounted parallel to this using two thru bolts
Aftermarket: Both B&M (available from Summit Racing PN BMM 45048) as well as Hurst (PN 3910113) make aftermarket short throw shifters. (We do not carry these)

Conversion Packages
High Impact offers custom engineered conversion packages. Complete NV3550 installation packages are available for MANY vehicles. These include needed Bellhousing or adapter, any needed clutch components, transfer case adapters. Transmissions are custom configured with correct input/output shaft as is optimum for the application.
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!
