How to Identify a NV3500 Transmission
- 1). Check the shift rail on the transmission. This particular transmission has a single shift rail, instead of a rail for each gear. All three shift forks are mounted on the shaft. The shaft is supported -- in the front and rear housings -- by bushings and one linear ball bearing.
- 2). Look at the body of the transmission. It has a front half and a back half. You can see where it comes apart between the two halves, as you must split it where it comes apart to service it. The front and back halves are both aluminum.
- 3). Locate the plugs. The NV3500 has a fill plug on the front housing, on the passenger side. It also has a drain plug on the bottom of the front housing.
- 4). Look at the overall shape of the transmission. The bellhousing, where it mounts to the engine, is larger in diameter than the tailshaft. The shifter is located on the back half of the transmission.
