* For automatic transmissions: The VSS is typically located on the driver's side of the transmission, near the top. It's often a small, cylindrical sensor with a single wire connector. You'll likely need to get under the truck to see it clearly.
* For manual transmissions: The VSS is usually integrated into the tail housing of the transfer case. Again, access requires getting under the truck.
To be certain:
1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have diagrams showing the exact location and will often specify the sensor's appearance.
2. Check online forums specific to 1995 Chevy Silverado 4x4s: Search for "1995 Silverado 4x4 transmission speed sensor location" on forums like Chevrolet forums or truck-specific forums. You'll find images and descriptions from other owners who have located the sensor.
Without knowing your transmission type (automatic or manual), pinpointing the exact location is impossible. Always be cautious when working under a vehicle and use jack stands for safety.
