* 3-speed automatic (TH350): This was a very popular choice for light-duty trucks of that era.
* 4-speed manual (SM465): Also a common option, particularly with larger engines or for those who wanted more control.
* 5-speed manual (NV350): Less common than the 3-speed automatic or 4-speed manual, but still possible.
To know for sure what transmission is in *your* specific truck, you need to check:
* The build sheet (if you have it): This will list the exact specifications of your truck.
* The VIN number: A dealer or online VIN decoder might be able to provide transmission information.
* The transmission itself: Look for markings on the transmission case; this usually identifies the type.
Without more information about your specific truck, it's impossible to say definitively which transmission it has.
