When it is working, it performs magnificently - increasing MPG by at least 1.5 MPG by itself and enabling aero improvements to the truck to bear fruit,.

But it is not very reliable. It has more bugs than coastal Guatemala and now it is leaking fluid.

Maybe I would have been smarter to have had an adapter made and installed a Tremec 6060 instead. I would have lost only 30 ft-lb torque rating (my old 444 doesn't make that much torque anyway - it dynos out at 560 ft-lb peak) and I would have gotten a better overall overdrive ratio(0.5:1 instead of 0.562:1) with only a single overdrive gear and the reliability of a manual shift transmission.
