Keeping your transmission safe is key to keeping your Peterbilt 362 on the road and earning.
- You must identify your specific transmission (e.g., Allison automatic, Eaton Fuller manual) before purchasing a kit.
- Symptoms like harsh shifting, whining noises, or a burning smell point to a clogged filter and require immediate attention.
- The wide price range ($12-$130) is due to different kit types; a simple spin-on filter is cheap, while a full automatic kit is more expensive.
- Quality aftermarket brands like Wix are a reliable choice for this vehicle.
Signs of a Failing Transmission Filter
A clogged transmission filter can't be ignored. If the filter is blocked, it can starve the transmission of fluid, leading to serious and expensive damage. Watch for these warning signs:
- Shifting Problems: You might feel hesitation, slipping, or harsh, jerky shifts between gears. This happens because the clogged filter can't provide the steady fluid pressure needed for smooth gear changes.
- Strange Noises: A whining or buzzing sound from the transmission area can be a sign of trouble. You might also hear rattling noises if contaminants are circulating in the system.
- Burning Smell: A burnt odor is a serious warning sign. It can mean the transmission is overheating because of restricted fluid flow, which is a fire hazard.
- Fluid Leaks: If the filter is clogged, pressure can build up and cause seals or gaskets to fail, leading to leaks.
Choosing the Right Aftermarket Transmission Filter Kit
For the 1991-1996 Peterbilt 362, you'll likely have either a manual Eaton Fuller transmission or an Allison automatic. It is critical to identify which transmission you have before buying a kit. The parts are not interchangeable.
Pro Tip: Check the data plate on your transmission housing to get the exact model number. This is the best way to ensure you order the correct filter kit.
The large price difference you see, from around $12 to over $130, is usually because of the type of kit. A simple spin-on filter for a manual transmission's cooling system will be on the lower end. A complete kit for an Allison automatic, which includes internal filters, O-rings, and a pan gasket, will be at the higher end of the price range.
Aftermarket Brand Tiers
- Premium Aftermarket (Wix): Wix is a well-respected brand known for making high-quality filters. They are a trusted choice for heavy-duty applications and are often considered equivalent to or even better than other brands in terms of construction and filtering capability.
- Standard Aftermarket (ATP): ATP (Automatic Transmission Parts) has been a supplier of transmission components since 1955. They offer a wide range of parts and are a common choice for general repairs. While generally considered reliable, some users have reported issues with how gaskets are packaged, which can lead to damage.

Frequently Asked Questions (FAQ)
How often should I change the transmission filter on my Peterbilt 362?
For a heavy-duty truck like the Peterbilt 362, it's best to follow the service interval recommendations from the transmission manufacturer (like Eaton or Allison). As a general rule, changing the fluid and filter is a key part of routine maintenance and should not be skipped. If you notice any symptoms of a clogged filter, it should be inspected immediately.
What comes in a typical transmission filter kit?
This depends heavily on the transmission. A kit for an Allison automatic might include two filters, a pan gasket, and several O-rings. A kit for a manual transmission might just be a single spin-on filter.
Why is there such a big price difference between kits?
The price reflects the complexity of the kit. A single spin-on filter is inexpensive. A comprehensive kit for an automatic transmission with multiple filters, a high-quality gasket, and seals will cost significantly more. Always verify what your specific transmission requires.
Is an OEM filter better than an aftermarket one for my truck?
While OEM parts are always a safe bet, high-quality aftermarket brands like Wix are widely used and trusted by mechanics and fleet operators. For a vehicle of this age, a quality aftermarket part offers a good balance of performance and value. Standard aftermarket brands like ATP are also a viable option for many repairs.
