Sonnax 34998-01K Wiring Harness Connector Bracket for GM 4L80E 4L85E Transmissions

The Sonnax 34998-01K wiring harness connector bracket retains the internal harness connector even though the retention tabs may be broken, providing a cost-effective solution for GM 4L80-E and 4L85-E automatic transmissions. It is common for one of the three plastic retention tabs to break on the wiring harness case pass-through connector in GM 4L80-E and 4L85-E units, which can push the connector into the case and require expensive harness replacement.

Key Features:

• Bracket firmly holds the connector in place from inside the pan using existing hardware
• Includes bracket and bolts (2)
• Saves the cost of replacing an expensive wiring harness
• Professional-grade Sonnax quality construction
• Easy installation using factory mounting points

Important Compatibility Note: 4L80-E and 4L85-E units use two different wiring harness connector styles. The early style has exposed terminals and a red rubber gasket. The late style has a gray plastic enclosure surrounding the terminals. The Sonnax bracket 34998-01K works only with the late style connector.

This bracket provides a permanent repair solution that prevents connector damage during external harness connection, eliminating the need for costly wiring harness replacement and reducing labor time.
