This item works.
My used 2011 GMC sierra. While slowing down, the v4 indicator came on and the stabilitrac light came on. It started running badly. I barely got it to the garage. after 2 garage jobs. tune up, then Catalitic converter and sensor change, it did it again. This Item so far has fixed the problem. For now I can use the truck. I still have 2 code lights to eliminate.

Tahoes transmission shifting.
It did exactly what it was supposed to do, now I enjoy driving my Tahoe without that changing from 8 cylinders to 4 cylinders driving me crazy, I highly recommend it.

Says it wont hurt your vehicle, thats a lie.
Not good for your vehicle, keeps your check engine light off and wont let your vehicle tell you if there is a problem that needs attention. Do not use. If something happens and your check engine light needs to come on,this device wont allow it. It clears your dtcs without your knowledge. Wouldnt recommend
