Fit my 3550 Tremec perfectly. High quality double O-ring… won’t leak . It’s not cheap, but I’m convinced it is worth the money

Speedo Adaptor Holding Bracket

The original tab, that came with my transmission, does not work on your product. You have a picture of the speedo adaptor with a tab. There is no tab/holding bracket included. I searched your site and I see other brackets for other transmissions but none for a tkx.
