The install was straight forward. The part worked great for about a month, and had now failed, and is acting worse than the original part I replaced.

This part seemed to fix my issue. May not know for sure until next winter as the problem with Range Shift Inhibited message was mostly on cold wet mornings and the weather has warmed up now here. It did surprisingly seem to make it shift much smoother than before. It wasnt that difficult to install and got me going again and the price was less than half what I could find at local parts store. Thanks again 1A Auto!

It did not work correctly on my Allison transmission. The gear selectors PRND321 were not calibrated correctly. I had to replace with a genuine Allison part.
