* Automatic Transmission: The dipstick and fill point are usually located on the passenger side of the transmission, near the back. It's a long, slender dipstick with a handle. Look for it near the transmission, often with a small cap or dipstick tube. It may be slightly difficult to access, so you may need to use a flashlight.
* Manual Transmission: Manual transmissions don't have a dipstick. The transmission fluid is generally checked and filled through a fill plug on the side of the transmission case. You'll need a workshop manual or to consult a mechanic to find the correct plug and procedure as there are various locations depending on the specific transmission. Improper filling can lead to damage.
To find the correct location:
1. Check your owner's manual: This is the best place to start. It will specifically state the location for your vehicle's transmission type.
2. Locate the transmission: The transmission is typically located towards the rear of the engine compartment and below the engine.
3. Look for a dipstick with a marking for transmission fluid level: This is the most common way for automatic transmissions.
4. If no dipstick is found: It's highly likely a manual transmission and you should not attempt to add fluid without a proper manual and the correct tools.
Important Note: If you're unsure, consult a repair manual specific to your 1992 Chevrolet G20 van and its transmission type (automatic or manual). Adding the wrong type or amount of fluid can severely damage your transmission.
