This fluid is fantastic. I bought a 2018 Chevrolet Spark with 30K miles and had a bad transmission shudder. Drained the transmission, cleaned-out the pan, and replaced the filters. Old fluid was black and this is a clear green. I loved the jug as it had a pop-up spout that was small and easy to pour, and the jug has a side handle. Transmission works great and the shudder is gone. I plan to change the filters and fluid again after 1K miles. This fluid is well worth the money!
