It is designed for use in longitudinal applications attached to the front-located engine with a standard bell housing. It is a hydraulic (hydramatic) design sharing much with the 8L90 transmission.[1] Estimated weight savings over the heavier duty 8L90 is 33 pounds. Gear ratios used enable a wide 7.0 ratio spread.
