This is a Chinese copy. It will probably work, but don’t know yet. Just so you know what you’re getting
Update; This part never did work, caused several hours of diagnosis and possible damage to the transmission band. The picture shows what it looked like after 10 miles in my transmission

Great and easy upgrade for the 4l60E. Easy to install and you will notice the difference immediately
Amazon Customer –
I verified with the original manufacturer. Do not trust the information on this listing.

The seals were the wrong size causing the servo not to travel correctly. In my case it’s a 10 hour job to remove them and I neither have the time or inclination to do that removal in triple digit heat.
