Transmission Electrical Connector:

DESCRIPTION
The transmission wiring connector is a very important part of the transmission operating system. Any interference with the electrical connection can cause the transmission to set diagnostic trouble codes (DTC)s and / or affect proper operation.

The following items can affect the electrical connection:

- Bent pins in the connector from rough handling during connection and disconnection.

- Wires backing away from the pins or coming uncrimped (in either internal or external wiring harness).
- Dirt contamination entering the connector when disconnected.
- Pins in the internal wiring connector backing out of the connector or pushed out during reconnection.
- Excessive transmission fluid leaking into the connector, wicking up into the external wiring harness, and degrading of the wire insulation.
- Water / moisture intrusion in the connector.
- Low pin retention in the external connector from excessive connection and disconnection of the wiring connector assembly.
- Pin corrosion from contamination.
- Broken / cracked connector assembly.

Points to remember when working with the transmission wiring connector assembly:

- To remove the connector, seize the two tabs towards each other and pull straight up (refer to image).
- Carefully limit twisting or wiggling the connector during removal bent pins can occur.
- Do not pry the connector off with a screwdriver or other tool.
- To reinstall the external wiring connector, first orient the pins by lining up the arrows on each half of the connector. Push the connector straight down into the transmission without twisting or angling the mating parts.
- The connector should click into place with a positive feel and / or noise.
- Whenever the transmission external wiring connector is disconnected from the internal harness and the engine is operating DTC(s) will set. clear these DTC(s) after reconnecting the external connector.
