4L60E, 4L65E, 4L70E

Symptoms:

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

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:
Sonnax wiring harness connector bracket positively supports the connector and prevents it from pushing into the case even if the plastic retention tabs are broken.

It is common for one of the three plastic retention tabs to break on the wiring harness case pass-through connector in GM 4L60-E, 4L65-E and 4L70-E units. 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 wiring harness connector bracket retains the internal harness connector even though the retention tabs may be broken.

• Bracket firmly holds the connector in place from inside the pan using existing hardware
• Connector bracket saves expensive wiring harness replacement.
