* 3-speed automatic (36RH/46RH): This was the most common automatic transmission. The difference between 36RH and 46RH is largely internal and related to torque capacity. You'd need to check the transmission's case for markings to determine the exact type.
* 5-speed manual (NV3500): A 5-speed manual transmission was also available.
To know for sure which transmission is in *your* specific truck, you'll need to:
* Check the VIN: Decoding the VIN can sometimes reveal the transmission type.
* Look under the hood: The transmission's identification tag is usually located on the side of the transmission case.
* Check the owner's manual: If you have the original owner's manual, it will specify the transmission.
* Check the build sheet (if available): A build sheet from the original purchase could also specify the transmission.
The best way to find out is to physically inspect the vehicle.
