Doing transmission work on an NV 5600 is no simple task and I am no expert, but will do my best to describe the work that I performed. The first step is to get the transmission out of the truck.
I have a 4X4 so if you have a 2 wheel drive model it will be a little easier. As always safety is the most important thing, so first thing is to disconnect the negative terminals of the batteries (you will be removing the starter and don’t want anything to turn over should you bump something). First you have to remove everything that is connected to, or will get in the way of the transmission. These things include, shift tower, starter, clutch release cylinder, reverse sensor wires, driveshafts (front and rear), transfer case linkage, vacuum lines, and suspension cross member. I recommend using plastic bags for nuts and bolts to keep them separate and make it easy to put back together.
Most of the stuff is metric, but I used both metric and standard sizes, just using which ever one fit tighter. I also recommend 6 point whenever you can use it. To remove the shift tower you will probably have to remove your center console. To do this you will have to remove a couple screws. You will have to remove the boots on the two shift sticks. The transfer case shifter just snaps into place and the main stick boot bolts into place. If you lift the bottom wrinkle, you will be able to see those bolts.

I removed the transfer case shifter (10 mm) to make it easier to get the console out. Once you have those two unbolted you will be able to lift them up to find the bolts that hold the center console in. There are also two bolts underneath the rubber in the cup holders. A small screw driver works well to help pull the rubber out.


Once you have the center console out you can remove the lower dust boot and then take out the 4 bolts to remove the shift tower.


The clutch release cylinder is removed by taking out two bolts and just pulling straight out. It is located on the driver’s side.

To remove the starter there are three bolts. The bolts look a little strange but a 10mm 12 point wrench or socket will take them out just fine. The top one is hard to reach but if you feel around you can find it and get a wrench on there. It is located on the driver’s side.
