Bracket 4L60E

Bracket 4L60E 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.
