The 246 GM transfer case is a specific part code that appears on vehicle titles to identify the type of all-wheel-drive or four-wheel-drive system installed in certain General Motors trucks and SUVs.
When you buy or sell a vehicle with this system, the title document will note "246" in the section describing the vehicle's drivetrain. This code tells you — and any future owner — exactly which transfer case the vehicle has, which matters for repairs, parts replacement, and resale value. If you're reading a title and see this notation, it means the vehicle has a specific GM part rather than a different transfer case model.
The transfer case itself is the mechanical component that splits engine power between the front and rear wheels in four-wheel-drive vehicles, or manages power distribution in all-wheel-drive systems. The "246" designation is GM's internal part number for one particular version of this system, used in certain model years and truck lines.
Key Takeaways
- The 246 code on a title identifies a specific General Motors transfer case model used in certain trucks and SUVs.
- This notation appears in the vehicle description section of the title document and becomes part of the permanent record.
- Knowing your transfer case model matters when you need repairs, replacement parts, or when you sell the vehicle.
- The 246 transfer case is different from other GM transfer case models, so mechanics need this information to service your vehicle correctly.
Where the 246 code appears on your title
The transfer case designation shows up in the vehicle description area of your title, usually grouped with other technical details like engine size, body type, and transmission. Different states format this section slightly differently, but the information is always there once the vehicle is first registered.
When you receive your title from the state DMV or motor vehicle department, look for a section labeled "Vehicle Description," "Vehicle Information," or "Technical Specifications." The 246 code will appear alongside other drivetrain details. This information stays on the title for the life of the vehicle — it does not change when you transfer ownership.
Why this information matters for repairs and maintenance
Mechanics need to know which transfer case your vehicle has because different models require different service procedures, fluid types, and replacement parts. If a shop orders the wrong part or follows the wrong repair manual, you could end up with a component that does not fit or work correctly. Giving them the 246 designation from your title ensures they have the right information from the start.
Transfer case repairs can be expensive, and using the correct part the first time saves you money and time. If you ever need to replace your transfer case entirely, the 246 code tells the parts supplier exactly which unit to send. This is also useful information to have if you are shopping for a used transfer case from a salvage yard or online parts retailer.
Transfer case codes and vehicle resale value
When someone buys your vehicle, they may want to know the specific transfer case model — especially if they plan to use the truck for off-roading, towing, or other demanding work. The 246 designation tells them what capability and durability level the vehicle has. Some transfer case models are known for handling heavy loads better than others, which can affect what a buyer is willing to pay.
Having the correct code on your title also protects you as a seller. It shows the vehicle's history is documented accurately and that you are being transparent about what the buyer is getting. If the title lists a different transfer case code than what is actually in the vehicle, that is a red flag for buyers and can create legal problems during the sale.
How transfer case codes relate to four-wheel-drive and all-wheel-drive systems
The transfer case is the component that makes four-wheel-drive and all-wheel-drive systems work. In a four-wheel-drive vehicle, the transfer case lets the driver switch between two-wheel-drive and four-wheel-drive mode, usually with a lever or button. In an all-wheel-drive vehicle, the transfer case automatically distributes power to whichever wheels need it.
The 246 is one of several transfer case models GM has used over the years. Other GM vehicles might have a 208, 231, 241, or other codes. Each one has different capabilities, efficiency levels, and maintenance needs. Knowing which one you have helps you understand your vehicle's actual four-wheel-drive or all-wheel-drive performance and what it can safely handle.
What to do if the transfer case code on your title seems wrong
If you believe the 246 code on your title does not match the actual transfer case in your vehicle, you can contact your state's DMV or motor vehicle department to request a correction. You will typically need to provide documentation — such as a mechanic's inspection report, service records, or the vehicle's original window sticker — that shows what transfer case is actually installed.
The correction process varies by state, but most DMVs can issue a corrected title once you submit the evidence. This is important to handle before you sell the vehicle, because a mismatch between the title and the actual vehicle can delay or derail a sale. If you recently purchased the vehicle and discovered the discrepancy, contact the seller or the dealership where you bought it — they may be responsible for ensuring the title is accurate.
Understanding transfer case maintenance based on your model
Once you know you have a 246 transfer case, you can look up the specific maintenance schedule for that model. Transfer cases need fluid changes at intervals recommended by GM, and the type of fluid matters. Using the wrong fluid can damage the internal components and lead to costly repairs.
Your vehicle's owner manual will reference the transfer case model and tell you when to service it. If you have lost your manual, you can find this information online by searching for your vehicle's year, make, and model along with "transfer case maintenance." Knowing the 246 designation helps you find the exact information that applies to your vehicle rather than general four-wheel-drive maintenance information that might not fit your specific system.
Frequently Asked Questions
What does 246 mean on a car title?
The 246 is a General Motors part code that identifies the specific transfer case model in your vehicle. It appears in the vehicle description section of your title and tells mechanics, buyers, and service shops exactly which transfer case system your truck or SUV has.
Do all GM four-wheel-drive vehicles have a 246 transfer case?
No. GM has used many different transfer case models over the years, each with its own code. The 246 is one specific model used in certain trucks and SUVs during particular model years. Your vehicle might have a 208, 231, 241, or another code instead.
Can I change my transfer case to a different model?
It is technically possible but expensive and complicated. Changing transfer cases requires mechanical work, and the new part must be compatible with your vehicle's transmission and drivetrain. This is not a common modification, and you would need to work with a specialist shop. The title would need to be updated to reflect the change.
Why do I need to know my transfer case model?
Knowing your transfer case model ensures you get the correct repair parts, the right service procedures, and accurate information about your vehicle's capabilities. It also protects you when selling the vehicle, because buyers can verify the drivetrain matches what is documented on the title.
Where can I find the 246 code if I do not see it on my title?
Check the vehicle description or technical specifications section of your title. If it is not there, contact your state's DMV with your vehicle identification number (VIN), and they can tell you what transfer case code is registered for your vehicle. You can also ask a GM dealership to look it up using your VIN.
