NV3550 5-speed Conversions by High Impact Transmission and Gear
Aug 18, 2006
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.
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.
They have on-line kit descriptions up for these items:
- Jeep Wrangler 2.5L 4cyl (replacing AX5)
- Jeep Wrangler 87-88: Peugeot Replacement
- Ford Bronco 66-77
- Jeep Wrangler 4.0L

Their 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!
