Product Description
GM Automatic Transmission Harness Repair Pigtail – 20-Wire Pre-Pinned Connector
Fits Select 4L60E, 4L65E, 4L70E, 4L80E, 4T40E, 4T65E, 4T80E & Allison LCT1000 Transmissions
Repair a damaged automatic-transmission wiring-harness connection with this pre-pinned GM transmission connector pigtail. All 20 wire positions are populated, providing the circuits needed to support a wide range of compatible rear-wheel-drive, front-wheel-drive and Allison transmission applications. Because individual transmissions may not use every available circuit, the new wires must be matched to the original vehicle harness or the applicable factory service wiring diagram during installation. Supplied compatibility includes select 4L60E, 4L65E, 4L70E, 4L80E, 4T40E, 4T65E, 4T80E and Allison LCT1000 five- and six-speed transmissions.
Key Features & Benefits
- Transmission Harness Repair Solution: Replaces a damaged transmission-side connector or compromised section of the original wiring harness without requiring replacement of the complete vehicle harness. The pre-wired configuration provides accessible wire leads for splicing into the existing transmission circuit.
- All 20 Wire Positions Pre-Pinned: Every available connector position arrives populated with a wire, providing coverage for compatible transmission applications with different circuit requirements. Unused wires can be identified by comparing the pigtail with the original connector and applicable factory wiring information.
- Broad GM Transmission Coverage: Supplied applications span popular electronically controlled transmissions, including the 4L60E, 4L65E, 4L70E and 4L80E families. Coverage also includes compatible 4T40E, 4T65E, 4T80E and Allison LCT1000 five- and six-speed transmissions.
- Supports Accurate Circuit Matching: The individual wire leads allow each required transmission circuit to be matched with the corresponding wire in the original vehicle harness. This is important because circuit usage and wire assignments can vary by transmission, model year and vehicle application.
- Extensive Model-Year Range: Supplied application coverage begins with 1991 4L80E transmissions and extends through 2020 Allison LCT1000 applications. The listed year ranges help narrow the appropriate transmission family before the individual wire circuits are matched.
Notes
- Not every transmission uses all 20 wires included with this connector.
- Match each circuit to the original harness or the correct factory service wiring diagram when splicing the pigtail.
