You only need a few NV4500 parts for common issues, but if you’re going to tackle this job, it’s worth installing a full NV4500 transmission rebuild kit, or at least a bearing, gasket and seal kit. Most of the transmission can be disassembled with common tools, including screwdrivers, deep-well metric sockets and snap-ring pliers. As with other transmission rebuilds, you will also need a bearing puller, a bearing splitter and a bearing press to slide bearings on and off of the shafts, as well as a dial indicator to check end play. For full disassembly, you also need a special slotted wrench to remove the fifth gear nut.
