Rebecca D. (5/5)

Stopped and fixed my harness

"Stopped and fixed my harness from leaking and cleared my codes I highly recommend it."

Charles G. (5/5)

Easy Fix

"133,000 on my duramax when I started seeing a little drip on the driveway. The connector on the trans was soaked. Looked like it had been leaking slowly for a while now. The connector seal is exactly what I needed. Easy and quick fix from outside the transmission. No more leak."

Tanner T. (5/5)

Lasted 2 weeks and then

"Lasted 2 weeks and then had the same issue. I ended up buying the internal trans harness and added sealant to the new connector. I'm hoping that makes it last longer than the stock seal cup."

Stefan C. (1/5)

Definitely took care of the Problem

"So if your transmission stumbles or has shifting issues. Over time the transmission fluid gets past the pigtail and you have to re seal it with one of these. And it’ll keep transmission fluid from getting in the connector. Beware removing will allow fluid to flow out best to drain the fluid out and add it back in."

Michael K. (5/5)

Easy replacement

"Very easy replacement, only needed to extract the outer seal (has only one clip) cleaned with electrical parts cleaner, added copious amounts of dielectric grease, snapped the new seal in…all good no more leak"

Robert G. (5/5)
