Dodge Durango Transmission Input Shaft Speed Sensor Guide (2000-2008)
Experiencing harsh shifting or a check engine light in your Durango? A faulty input speed sensor could be the culprit.
- A bad input speed sensor on a 2000-2008 Durango typically causes harsh shifting and may trigger a P0715 code.
- Replacement is a simple, one-bolt job that is very accessible for DIY repair on the side of the transmission.
- For the 45RFE/545RFE transmissions, the input and output sensors are often the same part.
- Quality aftermarket brands like NTK and Standard Ignition offer a reliable, cost-effective alternative to OEM Mopar parts.
Is Your Durango Shifting Hard? Understanding the Input Speed Sensor
If your 2000-2008 Dodge Durango is experiencing transmission problems like harsh shifting or getting stuck in gear, a faulty Automatic Transmission Input Shaft Speed Sensor is a likely cause. This sensor works with the output speed sensor to tell the vehicle's computer how to shift the gears properly. When it fails, the computer gets confusing information, leading to noticeable and sometimes severe driving issues. For this generation of Durango, which often uses the 45RFE or 545RFE transmission, the input and output sensors are separate, externally mounted parts, making replacement relatively simple.
Pro Tip: Check Your Codes
Before buying any parts, use an OBD-II scanner to check for diagnostic trouble codes (DTCs). A common code for a failing input speed sensor is P0715 (Input/Turbine Speed Sensor Circuit Malfunction). This code specifically points to an issue with the input sensor's circuit, helping you confirm the diagnosis.

When replacing a sensor, you don't always need to pay dealer prices for an OEM part. For a part like this, a quality aftermarket sensor can provide reliable performance for less money.
- NGK (NTK): NTK is the sensor division of NGK, a brand widely respected as an Original Equipment (OE) supplier for many automakers. Their sensors are known for high quality and are often considered a top-tier aftermarket choice, just below Mopar itself. They are engineered to match OE fit and performance.
- Standard Ignition (SMP): Standard Motor Products is a long-standing American company with a solid reputation in the aftermarket. While quality can sometimes vary across their broad product lines, they are generally considered a reliable choice for common electronic parts.
For a critical electronic sensor on your Durango, both NTK and Standard are reputable options. NTK often has a slight edge in perception due to its OE supplier status. However, both brands are a significant step up from no-name online marketplace brands and offer a good balance of quality and value.

Frequently Asked Questions (FAQ)
Where is the input speed sensor on a 2000-2008 Dodge Durango?
For Durangos with the 45RFE or 545RFE transmission, there are two sensors on the driver's side of the transmission case. The input speed sensor is the one located towards the front of the transmission (closer to the engine). The output sensor is located at the rear.
Are the input and output speed sensors the same part?
On many 45RFE and 545RFE transmissions used in this era of Durango, the input and output speed sensors are identical and interchangeable. They have the same part number. 🎬 Watch a mechanic replace both sensors on the 45RFE transmission. However, it is always best to confirm the part number for your specific vehicle.
Can I replace this sensor myself?
Yes, this is a very DIY-friendly job for most 2000-2008 Durangos. The sensor is held in by a single 8mm bolt and has an electrical connector. The job requires basic hand tools and can typically be completed in under 30 minutes.
