Default Nv4500 or nv5600 eletrical.

I'm looking to do a nv4500 or 5600 swap into my Cherokee. Does either of these trans require any electrical?

no but they are a rather large transmission and will require some decent fab to fit properly.

I have seen the NV4500 done in Xjs, and have personally swapped them into other trucks, such as my old S-10 jimmy. Even in the extremely tight S-10 trans tunnel I had plenty of room for the NV4500.

The NV4500 is very large, but most of the "meat" is on the bottom half of the transmission, and there shouldn't be many clearance issues. Several companies, including Advance adapters, offer NV4500 swap kits for your application. The NV4500 is a great transmission and you can't go wrong with it.

Make sure you start with a 95 or newer NV4500 though. The 92-95 GM models use a different bellhousing to trans bolt pattern that no-one offers adapters for. Without serious fab skills, the early transmissions only bolt up to stock GM applications. In 95, GM switched over to the common (dodge) pattern.

In the 4.0 jeep swap applications they use the dodge gasoline version of the NV4500. The V-10 HD application and Cummins application would require swapping out the input shaft. So if you don't have the trans already, it would be best to look for a V-8 gas dodge 95-01 NV4500. Otherwise you'll spend $100-$200 for a new input shaft, not including labor.

The NV5600 is a piece of crap. It was only used for a few years, and had so many problems it was quickly discontinued. Besides the massive size and weight, nobody offers adapters for these transmissions that were only offered behind cummins diesels. It is very common for them to loose 2nd gear. If you really want a 6 speed, you might want to consider swapping out one from a late model jeep. It's basically a bolt in.

I'm already built with d60 and 14 bolt rear end. 14inch coilovers in the front. And I'm goin to swap a 12v cummins into my rig. Its hard to find a Cheep 4wd doner truck to buy 2wd trucks are more easily to come buy I was just needing to know on if I needed to wire up a different trans or not. The front end has already been extended to accommodate the 12v and i cut the entire front unibody off and made it into more of a frame using 1.5 DOM

The 12 valve motor is going to be too long unless you push it over a foot into the firewall or hang it a foot out front. Plus that motor weighs twice what the original 4.0 did. You might be better to go with a 4bt instead.

A 2wd tranny will work fine if you swap out the tailhousing. Advance offers a tailhousing kit to change a 2wd NV4500 over to accept the jeep T-case pattern.
