The quickest way to identify a Chrysler transmission is to read the identification tag on the side of the case for the model code (examples include 727, A904, 41TE, 42RE, 46RE, 68RFE). If the tag is missing, you can use the vehicle’s VIN to confirm the original transmission and compare it with exterior cues and dealer databases.
Where to look for the ID tag
Most Chrysler automatic transmissions carry an identification tag or stamped codes on the case that list the model code, serial number, and date of manufacture. Knowing where to look and how to read the tag can save time when confirming the exact transmission family.
The following list explains what you should read on the ID tag and where to locate it on common Chrysler transmissions.
- Model code (for example: A904, 727, 41TE, 42RE, 46RE, 65RFE, 68RFE, 8HP70, etc.).
- Serial number (S/N) and date code or factory week/year.
- Manufacturer and occasionally a part or service number used for ordering components.
On many models, the tag sits on the transmission case on the driver’s or passenger’s side near the bellhousing. If the tag is missing or illegible, note exterior cues such as the bellhousing shape, pan design, and control linkage to help narrow the family, and cross-check with your VIN.
Using the VIN to identify the transmission
If the identification tag is gone or unreadable, your vehicle identification number (VIN) can still reveal the original transmission when decoded correctly. The VIN links your car to its factory options, including the transmission family, and can be checked with official sources or reputable online decoders.
Proceed with these steps to use the VIN for transmission identification.
- Locate the VIN (typically on the driver’s side dashboard near the windshield or on the driver’s door frame). Take a clear photo if possible.
- Enter the VIN into a trusted decoder or contact a Chrysler dealer to retrieve the original equipment list, focusing on the transmission option code.
- Match the decoded transmission code or family to known Chrysler transmission names (for example, 727, 41TE, 42RE, 46RE, 65RFE, 68RFE, 8HP series).
- Confirm that the identified transmission matches the vehicle’s year and engine combination by cross-checking with service manuals or factory literature.
Using the VIN provides a reliable path when the physical tag is missing, and it helps avoid misidentifying a replacement or swapped transmission.
Common Chrysler transmission codes you may encounter
Familiarizing yourself with common model codes can speed identification, especially when inspecting a used vehicle or a donor transaxle. The following codes cover several generations of Chrysler automatics.
- A904 (3-speed): Early small-car automatic used in various Chrysler products in the 1980s into the early 1990s.
- 727 TorqueFlite (A727): The classic three-speed automatic used in many rear-wheel-drive Chryslers and Mopars for decades.
- 41TE / 41TES (4-speed): Late-1990s to early-2000s lightweight four-speed family with electronic control.
- 42RE / 42LE (4-speed): Common four-speed transmissions in many Chrysler applications, mid-1990s to early 2000s.
- 46RE / 46RH (heavy-duty 4-speed): Strengthened four-speed used in larger cars and trucks, mid-1990s to early 2000s.
- 65RFE (5-speed): Five-speed automatic used in some mid- to late-2000s applications and trucks.
- 68RFE (6-speed): Six-speed automatic appearing in later 2000s to early 2010s Ram/Chrysler applications.
- 8HP/8HP45 and 8HP70 (ZF-supplied eight-speed): Modern eight-speed automatics used in several FCA models from the early 2010s onward; identification may show “8HP” on the case or require VIN confirmation.
Notes: Codes and configurations can vary by model year and region, and some vehicles may use hybrid or electronically managed variants. When in doubt, verify with the dealer or the official service manual for your exact year and engine combination.
Next steps: what to do if you’re working on or replacing the transmission
Once you’ve identified the transmission family, you can source the correct parts, service procedures, and torque specs. If you’re planning a repair, a factory service manual or a Chrysler-approved guide is essential for torque specs, valve body layout, and dipstick readings. If you’re buying a used transmission, confirm the exact model and ensure the bellhousing pattern, wiring harness, and mounting points match your vehicle.
Summary
Identifying a Chrysler transmission hinges on locating the case tag or decoding the VIN. Use the tag to read the model code, serial/date information, and cross-check with online resources or a dealer. If the tag is missing, rely on the VIN and exterior cues to determine the family, then consult service manuals for exact specifications and replacement parts. Knowing whether you’re dealing with a 3-speed TorqueFlite, a 4-speed family, a 5- or 6-speed unit, or a modern eight-speed helps you source the right parts and follow the correct service procedures.
How do I tell if I have a 4L60E or 6L80E?
Control like the other GM automatics the easiest way to identify a 4L80 is to look at the shape of the pan. And you can see compared to this 4L60 pan that the 4L80 pan is just enormous.
Can I look up my transmission by VIN number?
When available, the Free VIN Lookup will include the vehicle's year, make, model, trim, pricing, horsepower, fuel type, transmission, drivetrain, etc. Key features, installed options, packages, and specifications detailing engine information, and capacities are also provided in the VIN Lookup.
How do I figure out what my transmission is?
You can find your transmission type on your window sticker, a Build Sheet, or a Vehicle Identification (VIN) Decode Letter.
