GM Electrical Case Connector Seal
TransTec® electrical case connector seal for GM 4L60E, 4L80E, 4T80E, and Allison 1000/2000 series secures the electrical contact pins that connect the internal wiring harness to the vehicle harness, keeping oil sealed in and blocking contaminants out.
Installation is a snap. Easily remove the old seal by lifting the tab on the side internal harness and slide the old seal out from the main harness connector. Line up the guides in the OD of the TransTec® electrical case connector seal and push into the connector until it bottoms out and the tab locks in place.
