4l80e Wiring Plug

The 4l80e transmission has two speed sensors 4l60e only used one.

4l80e wiring plug. I guess the connector should push pull out once this is done. 4l80 e and 4l85 e units use two different wiring harness connector styles. Polarity does not matter. I just looked up the 4l80e and this is what it says about removing the wiring connector use a 1 15 16 12 pt socket to in order to release the pass through connector retaining clips from the case.

The late style has a gray plastic enclosure surrounding the terminals. You need a minimum 4 7 ohm or higher resistance up to 10 ohms 10 watt or more resistor such as digi key 4 7cwbk nd 1 67 on the pressure control solenoid wire from the trans connector pin d to the gpio board s pin 33.

You will now have two extra wires these will be used for the 4l80e s input speed sensor. Trans plug pin s.

Tci s 4l80e wiring harness is designed to replace an original harness and to update a pre 1993 4l80e transmission to a later style wiring harness.

The early style has exposed terminals and a red rubber gasket normally a 6 mm bolt in the center of the plug. Pre 4l80e transmissions use a different internal wiring harness and pass through connector.

This early harness has a problem with leaking fluid at the pass through connector.

Connector row pin pin name function wire color termination notes. The sonnax bracket 34998 01k works only with the late style connector. To wire the 4l80e transmission to the gpio board you need to make a number of connections. It does not matter where these two wires go in the two pin speed sensor plug.

Gm 4l80e transmission electrical connector has the potential to leak about a pint of atf onto the ground where you park and if it s really dirty under there it may not be obvious where it s all coming from. Gm recommends upgrading to the newer connector and wiring harness.
