Common sensors related to the automatic transmission in a 2004 Jeep Liberty and their general locations include:
* Input/Output Speed Sensors: These are typically located on the transmission itself, often near the transmission bell housing. One sensor measures the input shaft speed (from the engine), the other measures the output shaft speed. Their exact location can vary slightly depending on the specific transmission.
* Transmission Fluid Temperature Sensor: This sensor is usually located within the transmission pan or on the transmission case. Its job is to monitor the temperature of the transmission fluid.
* Throttle Position Sensor (TPS): While not directly *on* the transmission, the TPS is crucial for the transmission's control system as it tells the transmission how much throttle the driver is applying. It's located on the throttle body, typically near the engine.
* Vehicle Speed Sensor (VSS): This isn't directly on the transmission, but it's important for the transmission's operation, especially for shift points. It's usually located on the transmission tailshaft housing, or in some cases on a wheel hub or differential.
To find the specific sensor you need, you'll need:
1. The sensor's name or part number: This is the most helpful information. Look up your vehicle's repair manual (often available online) or a parts diagram for your specific transmission (e.g., 42RLE).
2. A diagram: A repair manual or online parts diagram will show the sensor's location.
3. A code reader: If you have a diagnostic trouble code (DTC) related to the transmission, that code might pinpoint the faulty sensor.
Without more information about which sensor you are looking for, I cannot give you a precise location.
