The National 710905 manual transmission shaft seal is a crucial component for maintaining the performance and longevity of your 2500 or 3500 series vehicle's manual transmission system. This high-quality seal is specifically designed to fit and function optimally in these models.

The seal is manufactured using advanced materials, including a durable, compression-molded elastomeric material for the seal body and a robust, heat-resistant rubber for the lip. These materials ensure a tight seal against transmission fluid leakage, even under extreme temperatures and heavy load conditions.

The National 710905 seal features a precise fit, with an internal diameter of 1.3 inches and an external diameter of 1.6 inches. The length of the seal is 2.2 inches, allowing it to effectively seal the transmission shaft where it meets the housing. Its design also includes a groove for the transmission shaft keyway, ensuring a proper alignment and secure installation.

The installation process for the National 710905 seal is straightforward. First, drain the transmission fluid and remove the old seal. Next, carefully install the new seal onto the transmission shaft, making sure it aligns properly with the groove. Finally, reinstall the transmission housing and refill the transmission fluid.

By using the National 710905 manual transmission shaft seal, you can prevent costly repairs and enjoy peace of mind knowing that your transmission system is sealed effectively and efficiently. This seal is an essential upgrade for any 2500 or 3500 series vehicle, especially for those with high mileage or a history of transmission leaks. Upgrade now and keep your vehicle running at its best.

Buying a manual transmission shaft seal, such as the National 710905, for a 2500 or 3500 model vehicle can address various issues related to transmission fluid leakage. Here are some pros and cons to help you make an informed decision:

Pros:

1. Seals Leaks: A faulty shaft seal can result in transmission fluid leakage, which can lead to further damage if left unattended. Installing a new seal can prevent these leaks and save you from potential repair costs.

2. Improves Performance: A properly sealed transmission ensures efficient operation of the vehicle. With a new seal, you may notice improved shifting performance and overall better driving experience.

3. Relatively Affordable: Compared to other major transmission repairs, a new shaft seal is a relatively affordable solution to address a transmission fluid leak issue.

4. DIY Friendly: Installing a new shaft seal can be a relatively straightforward project for those with basic mechanical skills and the right tools.

Cons:

1. Labor Cost: If you do not feel confident in installing the seal yourself, you will need to factor in the cost of labor to have a professional do it for you.

2. Potential for Additional Repairs: In some cases, a leaking shaft seal may be a sign of other underlying transmission issues. These hidden problems can add to the overall cost of the repair.

3. Availability: Depending on your location and the availability of the specific seal you require, there may be a wait time before you can get your hands on the part.

4. Disassembly Required: To replace the shaft seal, you will need to remove several components, including the driveshaft, transmission pan, and other related parts. This process can be time-consuming and require a significant amount of effort.

Conclusion:

The decision to buy and install a new manual transmission shaft seal, such as National 710905, for a 2500 or 3500 model vehicle depends on various factors. Consider your mechanical skills, availability of the part, and the overall cost, including labor, when making your decision. If you are comfortable with the project and have the necessary tools, installing a new seal can save you money compared to other transmission repairs. However, if you are unsure about the installation process or suspect additional transmission issues, it may be best to consult a professional mechanic for advice.
