Quality fluid for half cost in Mini CVT.
Size: 5 Quart Jug
Used in the cvt transmission in my 06 mini cooper. The fluid requirements recommended by BMW are met with this fluid. Fluid improved shifting and performance at half the cost of traditional BMW OEM fluid.

This CVT Fluid worked perfectly in a 2018 Chevrolet Spark.
Size: 5 Quart Jug
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!
