### ⭐⭐⭐⭐⭐ 







  
  
    Works for my semi truck
  

*by T***H on Reviewed in the United States on 9 April 2023*

If you have a semi truck with an automatic transmission, like me you may have experienced issues with the transmission getting confused and going into fault. After a while I decided to make it easier than disconnecting the battery every time and installed this cut-off switch. When I get a trans fault, hop out, reach for the cut-off and reset the ecm. I was concerned about the starting amperage being on a 4 battery Cummins truck but the truck starts as easy as without it. No issues at all. I recommend using this on a semi truck.
