Choosing the Right Transmission Filter Kit for Your 1983-1988 Autocar DK
Keep your Autocar's automatic transmission shifting smoothly by selecting the correct filter kit.
- First, confirm your Autocar DK has an automatic transmission, as these kits do not fit manual gearboxes.
- Choose a brand based on your preference for quality vs. value; Wix is a premium filtration specialist while ATP is a value-focused transmission parts supplier.
- Symptoms like harsh shifting, whining noises, or a burning smell indicate it's time to inspect your transmission fluid and filter.
- Due to the age of the vehicle, aftermarket parts are the primary option for replacement.
Is This The Right Part for Your Truck?
Before purchasing a transmission filter kit, you must identify the transmission in your 1983-1988 Autocar DK. These heavy-duty trucks were built with different options. Many were equipped with manual transmissions from makers like Spicer or Eaton, which often do not use an internal filter kit. The filter kits available from brands like ATP and Wix are designed for Autocar DK models equipped with an automatic transmission. Check your vehicle's specifications or inspect the transmission pan to confirm you have an automatic before ordering.
Symptoms of a Clogged Transmission Filter
A dirty and clogged filter restricts fluid flow, which can starve the transmission of the lubrication and hydraulic pressure it needs. If you notice any of these signs, your filter may need replacement.
- Delayed or Rough Shifting: The truck may hesitate when shifting from park into drive, or shifts may feel harsh and erratic.
- Unusual Noises: A whining sound that changes with engine RPM, or grinding and rattling noises during shifts, can point to a restricted filter.
- Burning Smell: Restricted fluid flow can cause the transmission to overheat, giving the fluid a burnt toast smell.
- Fluid Leaks: Increased pressure from a clog can sometimes force fluid past seals and gaskets, causing leaks.
- Loss of Power: The truck may feel sluggish or struggle to accelerate as the transmission fails to transfer power effectively.
Choosing Your Aftermarket Transmission Filter Kit
For a vehicle from this era, new OEM parts are generally unavailable. Aftermarket brands are your primary option. The quality of aftermarket parts can vary, so it's important to understand the differences between the available brands.
Brand Quality Comparison
| Brand Tier | Our Brands | General Quality & Notes |
|---|---|---|
| Premium Aftermarket | Wix | Wix is a highly respected filtration specialist. Their filters are known for high-quality construction and reliable performance, often meeting or exceeding OEM standards. They are a trusted choice for heavy-duty and commercial equipment. |
| Standard Aftermarket | ATP | ATP (Automatic Transmission Parts) specializes in transmission components and offers a wide range of parts that provide good value. While many users have positive experiences, be aware of potential quality control issues, such as gaskets being damaged in packaging. |
Pro Tip: Inspect the Gasket
Regardless of the brand you choose, inspect the pan gasket as soon as you open the box. Some brands have been known to fold composite gaskets, causing tears or weak spots that can lead to leaks after installation. If the gasket is creased or damaged, do not install it.
Estimated Costs for Replacement
The cost to replace the transmission filter kit will depend on the parts you choose and whether you perform the labor yourself or hire a professional mechanic.
| Part/Service | Estimated Cost |
|---|---|

| Shop Labor | $150 - $300 |
Frequently Asked Questions
How often should I change the transmission filter on my Autocar DK?
For a heavy-duty truck operating under severe conditions, a good interval is every 30,000 to 50,000 miles, or whenever you service the transmission fluid. Always consult your specific transmission's service manual if available.

Does the kit come with everything I need?
