However, the exact location can vary slightly depending on the transmission type (e.g., 4L60E, 700R4). You'll need to look closely at the passenger side of the transmission case near where the transmission lines connect. It's usually near the top or middle of the transmission.
To find it definitively:
1. Consult a repair manual specific to your 1993 Chevy Suburban. This will have diagrams and precise locations. A Haynes or Chilton manual would be helpful.
2. Use an online parts diagram. Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts often have diagrams that you can search by your vehicle's year, make, and model.
Be aware that accessing it might require getting under the vehicle. Always use safety precautions when working under a car (jack stands, etc.).
