The oring washers that come with this set are what makes it worth it
I ordered this specific set because the oring style washers it comes with.
You have to crank these down pretty tight to prevent them from leaking but they do the job great.
I’ve tried a similar listing with normal washers and I couldn’t get them to stop leaking.

This kit is only for 4L80E transmissions with one front fitting in one rear fitting.
I used these fittings on a 2003 4L80E general motors transmission.

Used when installing a 4L80E in my 1969 Chevelle
Trans fit fine without beating on the tunnel. These fittings made the install much easier since the clearance between the transmission and tunnel was limited.

Provide more clearance
I just got them in and upon inspection they appear to be of good quality, and provide fitment in a tight tunnel to run the transmission cooler lines. The thing I noticed was that no instructions were included, had to refer back to the product ad that shows the placement of the included washers. Im hoping that this banjo type fitting flows well.
