1983-1984 Chrysler E Class Automatic Transmission Oil Cooler Guide
Keep your classic Chrysler's automatic transmission shifting smoothly by addressing a failing oil cooler.
- Heat is the primary cause of transmission failure; a working cooler is essential for your E Class.
- Symptoms include fluid leaks, a burning smell, and poor shifting performance.
- Aftermarket brands like Hayden are a reliable and often superior replacement for the unavailable OEM part.
- Always consider replacing the flexible cooler lines at the same time as the cooler to prevent future leaks.
Is Your Transmission Cooler Failing?
For a car like the 1983-1984 Chrysler E Class, the original transmission cooler may be nearing the end of its life. Failures typically happen in two ways: leaks or blockages. Leaks can occur from corrosion on the cooler itself or from old, brittle connecting lines. Blockages inside the cooler can prevent fluid from circulating, leading to rapid overheating. Catching a bad cooler early can save you from a much more expensive transmission rebuild.
Symptoms of a Bad Transmission Cooler
Watch for these common signs that your E Class needs a new transmission cooler:
- Fluid Leaks: This is the most obvious symptom. You may see puddles of reddish or brown fluid under the front of your car. This indicates a leak from the cooler or its lines.
- Burning Smell: A sharp, burnt odor suggests the transmission fluid is overheating and breaking down. This is a serious sign that requires immediate attention.
- Slipping or Rough Shifting: When the fluid gets too hot, it loses its ability to lubricate and maintain pressure properly. This can cause the transmission to shift erratically, hesitate, or slip out of gear.
- Overheating: While your E Class may not have a dedicated transmission temperature light, a failing cooler can sometimes contribute to the engine running hotter, as it places extra load on the main cooling system.
Choosing the Right Aftermarket Cooler
For a vehicle from the early 1980s, finding a new OEM (Original Equipment Manufacturer) transmission cooler is highly unlikely. The aftermarket is your primary source, offering parts that meet or exceed original specifications. The two main brands you will find are Hayden and Four Seasons.
Brand Tiers: Hayden vs. Four Seasons
Hayden: Generally considered a top-tier choice for transmission cooling. Hayden specializes in cooling products and has a strong reputation for quality and performance. Reviews often praise their coolers for being well-made and effective at reducing transmission temperatures. For an owner looking for reliability and peace of mind, Hayden is a solid investment.
Four Seasons: This brand offers a wide variety of automotive heating and cooling parts and is a common choice in the aftermarket. While they produce reliable components, some mechanics and users in forums express a preference for specialists like Hayden, particularly for critical components like transmission coolers. A Four Seasons cooler is a functional replacement, but Hayden often has the edge in reputation for this specific part.
Estimated Costs for Replacement
The cost to replace the transmission cooler on your E Class will vary, but you can use this table as a general guide. Prices are estimates and can change based on your location and mechanic's labor rates.
| Part Type | Estimated Part Cost | Notes |
|---|---|---|
| New Aftermarket | $51.93 - $95.39 | This is the most common and recommended option. Price depends on brand and cooler style (tube-and-fin vs. plate-and-fin). |
| Shop Labor | $150 - $300 | Labor typically takes 1.5 to 2.5 hours. |
| Total Estimated Cost | $200 - $400 | Includes aftermarket part and professional installation. |
A Note on Cooler Lines
When replacing the cooler, it is highly recommended to replace the flexible rubber lines that connect it to the transmission's hard lines. Old rubber becomes hard and brittle, and new clamps on an old hose can often cause leaks. A few extra dollars for new hoses can prevent a major failure down the road.
Frequently Asked Questions (FAQ)
Can I install a transmission cooler myself?
Yes, this is a feasible DIY project for someone with moderate mechanical skill. It requires safely raising the vehicle, draining some fluid, and accessing the front of the radiator where the cooler is mounted. You will need basic hand tools, a drain pan, and potentially new hoses and clamps. However, if you are not comfortable working with transmission fluid lines, a professional mechanic can do the job relatively quickly.
Should I get a bigger cooler than the original?
For a stock 1983-1984 Chrysler E Class, a direct replacement size is usually sufficient. However, if you live in a very hot climate or do a lot of city driving, upgrading to a slightly larger cooler (often called a heavy-duty or plate-and-fin style) can provide extra protection and extend the life of your transmission. Hayden is well-known for these types of upgrades.
Do I need to replace my transmission fluid when I replace the cooler?
While not strictly required, it is an excellent time to do so. You will lose some fluid during the replacement, and the fluid's condition is a key factor in transmission health. If the fluid is dark or smells burnt, a full fluid and filter change is highly recommended to remove contaminants.
Are there any recalls for the transmission cooler on my Chrysler E Class?
There are no specific recalls or Technical Service Bulletins (TSBs) found for the automatic transmission oil cooler on the 1983-1984 Chrysler E Class. Any issues you experience are likely due to the age and wear of the original components.
Technical Specifications
The 1983-1984 Chrysler E Class was available with a 2.2L I4 or a 2.6L Mitsubishi I4 engine, both paired with a 3-speed Torqueflite automatic transmission (such as the A413 or A470). The transmission cooler is typically a tube-and-fin or plate-and-fin style unit mounted in front of the A/C condenser and radiator.
