The Ultimate LS ECU has the ability to control the shift point, shift firmness, when to downshift properly, and all other features involved when controlling the transmission. This feature is suitable for 4L60, 4L65, 4L80 or 4L85 GM transmissions. If using transmission control connect the two sides of the trans connector to the sub-harness and connect this to the connector on the transmission. Once connected to the transmission you are ready. If not using transmission control leave the connectors untouched.
