What transmission does a 97 Cummins have?

The 1997 Dodge Ram equipped with the Cummins 5.9L inline-six could come with either a manual or an automatic transmission. The two most common setups for that year were a five-speed manual NV4500 and a four-speed automatic 47RE. A stronger auto, the 48RE, was introduced later with the 24-valve Cummins and is not typically found in the 1997 12-valve models.

Transmission options for the 1997 Cummins

The 1997 Cummins-powered trucks offered two main transmission choices. Below are the primary configurations you would typically encounter on that model year.

• NV4500 5-Speed Manual — a heavy‑duty manual transmission used with the 5.9L Cummins, common on 2500/3500 trucks. It requires a clutch and a floor shifter, and is favored by those who tow heavily or prefer direct mechanical control.


• 47RE 4-Speed Automatic — the widely used automatic option behind the 5.9L Cummins in the 1994–1997 era, featuring a hydraulic/ electronic control system with a lockup converter. It provides ease of use but can require maintenance as the truck ages.

In short, a 1997 Cummins pickup could be paired with either a manual NV4500 or an automatic 47RE; the 48RE version did not appear on the 1997 12‑valve lineup and came later with the 24‑valve Cummins.

How to identify which transmission you have

Quick checks

Use a few straightforward tests to confirm the transmission type before you work on it or order parts.

• Clutch presence: If your truck has a clutch pedal, it’s almost certainly the NV4500 manual. No clutch pedal usually indicates an automatic.


• External markings: Look for stamping or a tag on the transmission case. “NV4500” identifies the manual, while “47RE” (or a similar auto code) identifies the automatic.


• Documentation: Check the VIN/build sheet or window sticker for the specified drivetrain; it will list the transmission code if available.

Using these checks will help you verify the correct transmission on a particular 1997 Cummins truck, which is important for maintenance, parts compatibility, and any potential upgrades.

Additional context and considerations

The 5.9L Cummins mesh with these transmissions in distinct ways. The NV4500 manual requires clutch operation and a compatible bellhousing, while the 47RE automatic uses electronic controls and a torque-converter setup. If you’re considering changes or upgrades—such as swapping to a different transmission or rebuilding—it's essential to verify bellhousing compatibility, pilot bearing, input shaft, and crossmember fitment. Consulting a knowledgeable shop or a truck-specific service manual is recommended to avoid fitment or service issues.

Summary

For a 1997 Cummins-powered Dodge Ram, the standard transmission options were the NV4500 five-speed manual or the 47RE four-speed automatic. The later 48RE was not typical for the 1997 12‑valve trucks and appeared with later generations and engine updates. Verifying the exact transmission on a given vehicle can save time on parts and repairs, and knowing which one you have informs maintenance plans and potential upgrades.

What year is 5.9 Cummins to avoid?

But here's the thing — not every 5.9 is worth your cash. If you're eyeing a 5.9-powered Ram built between 1999 and 2001, pump the brakes. You might be staring at the infamous "53 block" — a factory-cast engine block with a known flaw — under stress (read: doing diesel things), they're prone to cracking.

What years did Dodge use the 46RE transmission?

This transmission was home in the robust Dodge Ram 1500, 2500, and 3500 trucks, along with select Dodge Dakota and Dodge Durango models. It was offered in two exciting variations: 46RH (Hydraulic) – Used from 1988-1995. 46RE (Electronic) – Used from 1996-2003.
