* Automatic Transmission: Most likely, it's located on the output shaft of the transmission. You'll find it on the side of the transmission case, near the rear, often with a wiring harness connected. It's a relatively small sensor. Access might require getting under the vehicle.
* Manual Transmission: On a manual transmission equipped Suburban, the VSS is usually located on the transfer case. Again, you'll likely need to get under the vehicle to access it.
Important Note: Without knowing your specific transmission type (automatic or manual), it's impossible to be completely certain. The best approach is to:
1. Consult your owner's manual: This should have a diagram showing the location of major components, including the VSS.
2. Use a repair manual: A Haynes or Chilton manual for your specific year and model will have detailed diagrams and instructions.
3. Search online: Use a search engine with the terms "1995 GMC Suburban 4x4 VSS location [Automatic/Manual Transmission]" (replace "[Automatic/Manual Transmission]" with your actual transmission type). You might find images or forum discussions that show the location.
Remember to disconnect the negative battery terminal before working near any sensors or electrical components. Accessing the sensor might require some mechanical skills and tools. If you're not comfortable working on your vehicle, it's best to have a qualified mechanic locate and replace it.
