Transmission Filter Kit Guide for 1981-1990 Peterbilt 362 Trucks
Keep your heavy-duty transmission shifting smoothly by choosing the right filter kit for your Peterbilt 362.
- The correct filter kit depends on your truck's transmission model (e.g., Eaton Fuller), not the Peterbilt 362 model itself.
- Regularly changing your transmission filter is essential maintenance to prevent costly damage and extend transmission life.
- Wix is a highly-regarded brand for heavy-duty applications, while ATP is a viable budget-friendly alternative.
- Always inspect the new pan gasket for damage before installation to prevent leaks.
Symptoms of a Clogged Transmission Filter
A dirty or clogged transmission filter can't do its job, leading to problems that you might notice while driving. If your Peterbilt 362 is experiencing rough shifting, delays when changing gears, or unusual noises from the transmission, a restricted filter could be the cause. In more serious cases, a clogged filter can lead to the transmission overheating, which can cause significant internal damage. Paying attention to these symptoms and changing your filter regularly is key to avoiding expensive repairs.

When servicing your 1981-1990 Peterbilt 362, the most important factor is matching the filter kit to the specific transmission model in your truck, not just the truck model itself. These trucks were built with various transmission options, most commonly from Eaton Fuller. Always verify your transmission model before purchasing a kit.
Brand Tiers
For aftermarket parts, quality can vary. Here’s a breakdown of the available brands:
- Wix: Wix is a well-regarded brand in the heavy-duty truck industry. Their filters are known for quality construction and reliable performance, designed to protect transmissions against contaminants and minimize wear. Many professional mechanics and fleet operators trust Wix for its consistent quality.
- ATP (Automatic Transmission Parts): ATP offers a more budget-friendly option. Their kits are designed to meet original equipment specifications and include the necessary components for a filter change. While they are a cost-effective choice, some users have noted concerns about how gaskets are packaged, which can lead to damage. However, many users find them to be a good value for standard maintenance. 🎬 Learn more about the features of ATP transmission filters.
Pro Tip: Check the Gasket
Transmission filter kits include a new pan gasket. Upon receiving your kit, inspect the gasket immediately. Some brands fold the gaskets to fit them in the box, which can cause tears or weak spots, especially with composite materials. A damaged gasket will cause leaks, so it's better to catch it before you start the job.
