Symptoms:

  • Connector pushed into pan area
  • Retention tabs break off wiring harness connector

Cause:

The plastic retention tabs that hold the wiring harness connector in place are easily broken. Once broken, the connector may push into the case.

Correction:

This metal bracket positively supports the connector and prevents it from pushing into the case even if the plastic retention tabs are broken.

Wiring Harness Connector Bracket
Part No. 34998-01K

View Instructions

It is common for one of the three plastic retention tabs to break on the wiring harness case pass-through connector. This allows the connector to be pushed into the case when connecting the external harness. Not only does this require extra labor to fix, it also requires a new wiring harness. Sonnax has now developed two wiring harness connector brackets to retain the internal harness connector even though the retention tabs may be broken: 77980-01K for the 4L60-E, and 34998-01K for 4L80-E units with late-style gray connectors only.

  • Brackets firmly hold the connector in place from inside the pan using existing hardware.
  • Connector brackets save expensive wiring harness replacement

The 4L80-E unit uses 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 4L80-E bracket 34998-01K works only with the late style connector.
