Here's why you need more information:
* Transmission type: There are different types of manual transmissions used in the S-10 (e.g., 5-speed, 6-speed).
* Specific model: Even within the same year, the transmission can vary depending on the engine, trim level, and other factors.
* Current fluid condition: If you haven't changed the transmission fluid recently, it's likely due for a replacement.
How to find the right transmission oil:
1. Check your owner's manual: It will have the most accurate recommendation for your vehicle.
2. Look at the transmission tag: There should be a tag attached to the transmission itself, which may list the recommended fluid type.
3. Consult a mechanic: Your local mechanic can advise you on the correct transmission fluid for your specific model.
4. Use a reliable online resource: Sites like the Chevrolet website or a reputable parts store can often help you find the correct oil.
Important Note: Never use automatic transmission fluid (ATF) in a manual transmission. ATF has different properties and can damage your transmission.
