Buying a national SX-4Azm transmission shaft seal for a 1968-1974 Chevrolet P20 van can be a crucial decision for maintaining the performance and longevity of the vehicle's transmission system. Here are some potential pros and cons to consider before making a purchase:

1. OEM-equivalent quality: The SX-4Azm seal is manufactured by National Sealing, a reputable aftermarket parts supplier known for producing high-quality seals that meet or exceed OEM specifications.

2. Improved transmission performance: A leaking transmission shaft seal can cause a loss of transmission fluid, resulting in poor shifting, grinding gears, or even transmission failure. Replacing a worn-out seal with a new one can help prevent these issues and improve overall transmission performance.

3. Cost-effective solution: Compared to purchasing a remanufactured or new transmission, replacing the transmission shaft seal is a more cost-effective solution for addressing transmission issues.

1. Installation complexity: Installing the transmission shaft seal can be a challenging task, especially for those without mechanical experience. It may require the removal of the transmission pan and the use of specialized tools.

2. Potential for other transmission issues: A leaking seal could be a symptom of other transmission issues, such as worn-out bearings or damaged gears. Replacing the seal alone may not completely resolve the problem, and further repairs may be necessary.

3. Availability: Depending on your location and the availability of the parts supplier, it may take some time to receive the seal, which could result in a prolonged period of vehicle downtime.

Considering the pros and cons, buying a national SX-4Azm transmission shaft seal for a 1968-1974 Chevrolet P20 van can be a worthwhile investment for those seeking to maintain the performance and longevity of their vehicle's transmission system. However, it is essential to be aware of the installation complexity and potential for other transmission issues, as well as the potential for a delay in receiving the part.

If you are confident in your mechanical abilities and have the necessary tools, purchasing and installing the national SX-4Azm transmission shaft seal can be a cost-effective and efficient solution for addressing transmission issues in your 1968-1974 Chevrolet P20 van. Alternatively, consider seeking professional assistance from a qualified mechanic to ensure a proper installation and diagnose any potential underlying transmission issues.
