To find the correct dipstick length, you must identify the specific transmission in your Blazer. This information is usually found:
* On the transmission itself: Look for a stamped number or code on the transmission case.
* Your vehicle's documentation: Owner's manual or service records may specify the transmission type.
* Your vehicle's identification number (VIN): A dealer or parts store can use the VIN to determine the original transmission.
Once you know the transmission type (e.g., 4L60E, 5-speed manual, etc.), you can then find the correct dipstick length from a parts catalog, online retailer, or a mechanic.
