In short, the 1998 Dodge Ram 1500 4x4 could have either a four-speed automatic (46RE) or a five-speed manual (NV3500), depending on the engine and factory options. The exact unit varies by trim and production date, so checking the specific truck’s VIN or build sheet is the best way to confirm.
The Ram 1500 line from 1998 sits in Dodge’s second-generation truck lineup, offering two common transmission setups paired with the Magnum V8 engines of that era. The four-wheel-drive systems were typically paired with a transfer case that enabled 4x4 operation, but the transmission itself could be automatic or manual based on the original equipment configuration.
Automatic transmission option
Most 1998 Ram 1500 4x4s with everyday use and the common Magnum V8 engines came with the four-speed automatic transmission. The automatic option was designed for smooth acceleration, towing, and general utility in 4x4 applications.
- 46RE four-speed automatic (electronic control with overdrive)
The 46RE was the primary automatic transmission associated with many 1998 Ram 1500 4x4 builds, especially those equipped with the 5.2L or 5.9L Magnum V8 engines. It was designed to handle the torque of the V8s and work in conjunction with the 4x4 transfer case for off-road and adverse conditions.
Manual transmission option
A subset of 1998 Ram 1500 4x4 trucks were offered with a manual gearbox, appealing to buyers who preferred direct control over gear selection and towing feel. The manual option was relatively less common than the automatic but available on select configurations.
- NV3500 five-speed manual
The NV3500 manual was New Venture Gear’s five-speed transmission used in some light-duty Dodge trucks of that era. When paired with the 4x4 setup, it provided a traditional manual experience for buyers who valued engagement and potentially lower maintenance costs over the automatic’s convenience.
To determine the exact transmission installed on a given truck, you should verify the VIN or check the factory build sheet. Visual indicators include the presence of a gear shifter pattern in the cab for a manual (H-pattern with 5 forward gears) or the absence of a clutch pedal. The door tag or the glovebox VIN plate can point you to the original equipment list, and a dealer or reputable mechanic can decode the build information for confirmation.
How to verify the exact transmission on a specific vehicle
Exact transmission identification can be confirmed through several avenues. Start with the VIN and build sheet, then cross-check with the door tag or service records. If you’re unsure, a professional diagnostic from a Dodge service center or a knowledgeable independent shop can read the transmission code or identify the model directly from the transmission case.
- Check the driver’s door jamb tag for the vehicle’s options and original transmissions reference.
- Review the glovebox or under-hood labeling for transmission code stickers.
- Provide the VIN to a Dodge dealer or use a reputable online VIN decoder to pull the original options list.
- Inspect the pedal layout (presence of a clutch) and the shifter pattern to distinguish between manual and automatic variants.
Summary
For the 1998 Ram 1500 4x4, the two most common transmissions were the 46RE four-speed automatic and the NV3500 five-speed manual. The exact choice depended on engine, trim, and factory options. If you need to know the precise transmission for a specific truck, verify the VIN/build sheet or consult a Dodge technician to confirm the original equipment.
