It's relatively common on this transmission. There is an o-ring in there that is integral with the connector. From what I've heard, it's a simple pull out the old one and push in the new one.

I'm sure that one of our techs can provide more detail.

Requires a 7MM socket & ratchet.

None. It's on top of the transmission.

Note form another forum. Shop owner says the spacer is on national backorder.
Hopefully the o-rings are available as that's all you really need.

If you are going to the trouble of crawling under there, it would be smart to first buy the O rings, and do it pre-emptively.

Where is it? Easy. Find the wiring at the point where it enters the transmission at the front on top. 7mm bolt and pull it out the plastic spacer. Replace the rings , push it back in and replace the bolt. Smart to clean the dirt and gunk from the area before removal.
