Dodge Transmission Code by VIN: Identifying the Factory Gearbox
A Dodge VIN usually has no character dedicated to the transmission. The eighth character identifies the engine, but the gearbox paired with it is generally not encoded in the 17 characters, so a basic decode can only report a transmission type and number of speeds when that information was published for the VIN's model and year. To identify the transmission a specific Dodge was built with, look at its factory build sheet, where the transmission appears as its own sales code and description next to the engine, axle and drivetrain lines. The difference matters most where one engine was offered with more than one gearbox, such as a V8 Challenger that could be ordered with either a manual or an automatic.
What a basic decode shows
When you enter a VIN, the vehicle summary may include a transmission field such as "8-speed Automatic." That value comes from the VIN pattern for the model and year, not from a record of the individual car. It can be blank, and where a model offered two transmissions with the same engine, the VIN pattern often cannot tell them apart.
Treat the decoded transmission as a description of the model configuration. The build sheet is what identifies the unit a particular vehicle received.
How the transmission appears on a Dodge build sheet
On Chrysler-family build sheets, driveline equipment, including transmissions, transfer cases, clutches and related parts, commonly carries sales codes beginning with D. The description, not the prefix, tells you what a line is. Here is how the site's sales code navigator lists a few gearbox and driveline entries:
| Code | Navigator description | What it tells you |
|---|---|---|
| DPD | 11.5 " Clutch | A clutch entry, which points to a manual gearbox |
| DH9 | Short Throw Shift Lever | A shifter item, listed separately from the transmission |
| DHV | Electronic,Shift-On-The-Fly,F/Time T/Case | A four-wheel-drive transfer case: driveline equipment, but not the transmission |
| EF6 | 3.0L V6 5 Spd Man O.D | An older combined entry that names the engine and a five-speed manual together |
| DG5 | 4-Spd Auto,41Rle (Never Made Prod) | A planned four-speed automatic that the description itself marks as never built in production |
Two lessons follow. First, a record can carry several D-coded lines, and only one of them is the transmission. Second, code references include entries that were reserved or planned but never used, as the DG5 line shows, so finding a code in a list does not mean any vehicle carried it. The VIN's own record is what shows installed equipment.
Gearing entries sit nearby. The navigator lists lines such as DLF, "3.19 Overall Top Gear Ratio." Overall top gear combines the transmission's top gear with the axle ratio, which is why the gearbox and the rear axle are best read together; Dodge axle ratio by VIN covers the axle side.
Transmissions you are likely to find, by model
- Charger (2006–2023): automatic only. Earlier cars used four- and five-speed automatics; later cars moved to an eight-speed automatic.
- Challenger (2008–2023): an automatic was available throughout, and a six-speed manual was offered on many V8 versions. Because the same engine could come either way, the build sheet is the clean way to confirm a factory manual. The Challenger build sheet page goes further into that model's records.
- Durango (2011 onward): automatic, with five- and six-speed units in the first years of this generation and an eight-speed automatic from the 2014 model year.
- Grand Caravan (2011–2020): six-speed automatic with the 3.6L V6.
- Journey (2009–2020): a four-speed automatic with the 2.4L four-cylinder and a six-speed automatic with the V6.
The exact transmission model changed with engine, drivetrain and model year, so rely on the VIN's record rather than a model-wide assumption.
Why the exact transmission matters
- Service. Fluid type, fill procedure and filter parts differ between transmission families. The owner's manual specifies fluid by transmission, and the wrong fluid can cause shift problems or damage.
- Value. On cars where a manual was optional, buyers care whether it was factory-installed. The record shows how the car was built; a later conversion should be disclosed and priced as a modification.
- Towing. Trailer packages on some models bring cooling or other drivetrain-related items, which appear as their own lines when installed.
- Diagnosis. Knowing which unit you have makes it easier to judge shift behavior on a test drive and to find the right service information.
Checking the car against the record
Run the VIN through the lookup on the home page to see the decoded summary and, when available, the factory equipment listing. Then compare it with the car: count the pedals, look at the shifter, and during an inspection check the identification tag or stamping that most transmissions carry on the case. Confirm the engine line at the same time with Dodge engine codes by VIN, since engine and gearbox were paired at the factory.
The record reflects the vehicle as built, not repairs or replacements made since. What a record contains depends on the VIN, model year, market and source availability, and some VINs return none at all.
