Like most GM automatic transmissions that have come before it, the 8L90E has an aluminum case, overdrive, and can handle a lot of power. Through a combination of lightweight materials and wizardry, GM engineers were able to get the 8L90 to weigh in a couple of pounds less than the 6L80E, and keep it roughly the same size.
