Is Your Prowler's Transmission at Risk?
Heat is the number one enemy of an automatic transmission. For a unique vehicle like the Chrysler Prowler, with its rear-mounted transaxle, maintaining proper fluid temperature is critical. The automatic transmission oil cooler is the key component responsible for this. While generally reliable, these coolers can fail over time due to corrosion, damage from road debris, or simple wear and tear. Addressing failure symptoms early can prevent catastrophic transmission damage.
Symptoms of a Failing Transmission Oil Cooler
A bad cooler will give you several warning signs. The most obvious is a transmission fluid leak. Look for puddles of reddish or brown fluid under the rear of your vehicle. Other signs include a transmission overheating warning light on your dashboard, a distinct burning smell, or poor transmission performance like slipping gears, delayed engagement, or rough shifts. You might also hear new whining or grinding noises.
A Note on Leaks
Any transmission fluid leak is serious. Low fluid levels caused by a leak can quickly destroy your transmission. If you suspect a leak, check your fluid level and address the source immediately.
Choosing the Right Aftermarket Cooler
Since original Mopar parts for the Prowler can be difficult to find and expensive, the aftermarket is the go-to source for most owners. Fortunately, reputable brands offer quality replacements that often meet or exceed original specifications. Aftermarket coolers are typically either a "plate and fin" or "tube and fin" design. Plate and fin coolers are generally considered more efficient and durable.
- Good - Global Parts: This brand offers a direct-fit replacement option. While less information is available on brand reputation, it provides a functional and affordable solution.
- Better - Four Seasons: A well-known aftermarket brand that produces reliable, quality parts. Their coolers are pressure tested to ensure they are free of leaks. Think of Four Seasons as a solid, OEM-quality replacement that's a good value for the money.
- Best - Hayden: Hayden is a leader in performance cooling and a very popular choice for transmission coolers. Many owners of other vehicles use Hayden coolers as an upgrade over the stock unit for better cooling performance, especially if they live in hot climates or drive their vehicles hard. Their products are known for quality and efficiency.

Frequently Asked Questions
Can I replace the transmission cooler myself?
Yes, for a person with some mechanical skill, this is a manageable DIY job. The cooler is located at the rear of the car, behind the transaxle. Access involves removing a few nuts and bolts and disconnecting the cooler's electric fan. You will need to be prepared to catch some transmission fluid. Always use new, clean ATF+4 fluid when refilling.
Are there any recalls on the Prowler's transmission cooler?
No, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the automatic transmission oil cooler on the 2001-2002 Chrysler Prowler.
What's the difference between a plate-fin and tube-fin cooler?
Tube-fin coolers are a basic design where fluid runs through a tube with fins attached to dissipate heat. Plate-fin coolers are a more modern design where fluid passes through a series of plates, offering more surface area and better cooling efficiency, making them more robust.
Why is the cooler at the back of the car?
The Chrysler Prowler uses a rear-mounted transaxle, meaning the transmission and differential are combined into a single unit located at the rear of the vehicle. To cool the transmission fluid effectively, the cooler is placed nearby, where it can also get airflow.
