* 3-speed automatic (46RH): This was a very common option.
* 5-speed manual (NV3500): Less common than the automatic, but still a possibility.
To know for certain which transmission is in *your* specific truck, you need to check the following:
* The VIN: This will provide the most accurate information if you decode it through a VIN decoder (many free services are available online).
* The build sheet (if you have it): This document will specify the exact options of the truck.
* The transmission itself: Look for a tag on the transmission case; it will likely have a part number.
Without looking at one of these sources, it's impossible to say definitively which transmission a particular 1995 Dodge Ram 1500 5.9L has.
