This interfaces with quite a number of GM seats. It's a long list so I'll try to dig that out. It is specifically used for the recliner function in the power seats. I may have a few of these star shafts laying around that I can send if I find enough....maybe cut into pieces. I'll also see if we can find some scrap at our Tier 1.

Regarding efficiency I too was a bit surprised but that's what comes out of our dyno measurments. Actually too much efficiency is a problem in seat and window applications in that you don't want movement as the car bounces about on rough roads. In this motor there's a worm and two stages of spur gears for ~179:1 gear reduction.
