2001-2002 Chrysler Prowler Transmission Speed Sensor Guide
If your Prowler is stuck in gear or the speedometer is acting up, a bad transmission speed sensor is a likely culprit.
- The most common symptom of failure is the transmission getting stuck in 2nd gear, also known as 'limp mode'.
- It is highly recommended to replace both the input and output speed sensors at the same time to prevent future issues.
- This is a simple, low-cost DIY repair that can be done in under an hour with a 1-1/16" socket.
- There are no recalls for this part; the repair cost will not be covered by the manufacturer.
Is Your Prowler Stuck in Limp Mode?
A failing Automatic Transmission Output Shaft Speed Sensor is a very common problem for the 2001-2002 Chrysler Prowler. The most frequent and alarming symptom is the transmission forcing the car into "limp mode," where it gets stuck in second gear to prevent damage. This is a safety feature, but it makes the car unsafe to drive in normal traffic. You will almost certainly see a Check Engine Light on your dashboard as well. Because the symptoms of a bad input sensor and output sensor are nearly identical, and they are inexpensive parts located next to each other, it is highly recommended to replace both at the same time.
Choosing the Right Aftermarket Sensor
For a specialty vehicle like the Prowler, the quality of electronic parts matters. While an OEM Mopar sensor is an option, several reputable aftermarket brands offer reliable replacements that meet or exceed original specifications. Aftermarket parts are a cost-effective solution for this common failure.
| Brand Tier | Brands | Our Assessment |
|---|---|---|
| Premium Aftermarket | NGK, Standard Ignition (SMP) | Both NGK and Standard Ignition are well-known for producing high-quality sensors that are considered reliable, OE-matching replacements. They are trusted by professional technicians and are an excellent choice for durability. |
| Standard Aftermarket | ATP, Pioneer Cable | ATP specializes in transmission components and is a well-regarded brand in the aftermarket, known for good quality gaskets and kits. Pioneer is also a known provider of aftermarket cables and sensors. These brands offer a good balance of value and quality for a daily driver or a car that sees occasional use. |
| Economy | Skyward, True Tech | These brands provide a functional, low-cost repair option. While they may not have the long-standing reputation of the premium brands, they are a viable choice for getting your Prowler back on the road, especially on a tight budget. |
Cost of Replacing the Output Speed Sensor
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $13.98 - $38.64 |
| Shop Labor | $60 - $120 |
| Total Estimated Cost | $74 - $159 |
Pro Tip: The input and output speed sensors are located on the driver's side of the transmission. Replacing them is a simple DIY job that takes less than an hour with basic tools, primarily a 1-1/16" socket. Doing it yourself can save you the entire cost of labor.
Frequently Asked Questions
Do I have to replace both the input and output sensors?
It is very strongly recommended. They are the same age and have been exposed to the same heat and conditions. If one has failed, the other is likely to fail soon. Given the low cost of the parts, replacing them as a pair saves you from doing the same job twice.
What happens if I keep driving with a bad sensor?
You should not ignore this problem. Your Prowler will be stuck in second gear, making it slow and unsafe for most roads. This also puts extra strain on the transmission. You will also have an unreliable speedometer and no cruise control.
Are there any recalls for the Prowler's speed sensors?
No, there have been no recalls issued by the NHTSA for the transmission speed sensors on the 2001-2002 Chrysler Prowler. This is a repair you will have to pay for yourself.
My speedometer works but the transmission is in limp mode. Is it the output sensor?
Not necessarily. According to Prowler owner communities, if the transmission is in limp mode but the speedometer still works, the problem is more likely the input sensor. If the speedometer is dead and the car is in limp mode, it's more likely the output sensor. However, because the symptoms are so similar and diagnosis can be tricky, the best practice is to replace both.
