How do I tell which transmission I have?

You can find your transmission type by checking the driver's side doorjamb for a sticker, looking in your owner's manual, or inspecting the transmission itself for a stamped code or tag. The sticker on the doorjamb often has a "TR" symbol with a code next to it, while the transmission itself may have a metal tag or stamped number that can be researched online.

Methods to identify your transmission

Check the doorjamb sticker: Open the driver's side door and look for a white or colored label. It often contains a "TR" symbol followed by a code that can be used to identify the transmission.
Consult the owner's manual: The specifications section of your vehicle's owner's manual should list the transmission type.
Inspect the transmission:
- Visually: Look under the hood for the transmission, which is located in front of and slightly below the engine.
- Find a code: Look for a stamped code on the transmission's case or a metal tag attached to it.
- Use a jack: If you can't see it from the top, safely jack up the vehicle to get a better view from underneath and look for the code or tag on the transmission's left side, near the oil pan.
Use your VIN: The 17-character Vehicle Identification Number (VIN), found on the driver's side doorjamb or on the dashboard, can be used on "VIN decoder" websites to find basic information about your vehicle, including the transmission type.

How to identify a Dodge transmission?

To identify a Dodge transmission, check the driver's side door placard for a "TR" code, the owner's manual for transmission specs, or look for a stamped code or tag directly on the transmission housing. Other methods include using a VIN decoder or, for specific models, looking for physical characteristics like the type of electrical connectors or specific casting numbers on the transmission.

Method 1: Check vehicle information

Driver's side door placard: Open the driver's side door and look for a sticker, often white, with a list of codes. Find the code next to "TR" (for transmission) and use it to identify the transmission model.
Owner's manual: Check the "specifications" section of your vehicle's owner's manual, which should list the transmission type.
VIN decoder: Enter your vehicle's Vehicle Identification Number (VIN) into an online VIN decoder. The fourth through eighth digits can often provide information on the transmission type.

Method 2: Inspect the transmission

Look for a code on the housing: Check the transmission's metal case for a stamped code or a sticker/tag, especially on the side or near the bell housing.
Identify physical features:
- Connectors: Look at the electrical connectors. For example, the 48RE has a large, 5-pin connector, while the 47RH has a three-pin neutral safety switch.
- Casting numbers: Check for specific casting numbers, such as "238-2" on the bell housing, which is common on 47RH models.
- Tail housing: Note the length of the tail housing. A longer tail housing on some models indicates a four-wheel drive version.

Method 3: Use specialized resources

Transmission sales code chart: Use a Mopar transmission sales code chart, available online, to decode the information from the door placard or other official sources.
Contact a dealership or mechanic: A professional can help identify the transmission by cross-referencing your VIN or the codes found on the vehicle with their official databases.
