    Worth every penny.
  

*by B***A on Reviewed in the United States on January 31, 2021*

Works great.  Smooth shifting now and no P code. There is a method to replace this valve without removing the valve body available on YouTube. That’s how I did it. A little tough to do but better than removing the valve body. Plan on replacing the filter while you have the pan off.

    Fixed P1870 Harsh shift when hot 99 4l60e
  

*by D***. on Reviewed in the United States on August 10, 2023*

99 Chevy Tahoe would have a check engine light come on after a while and it would shift harshly after that. I tried a lot and found this and gave it a shot. Installation was very difficult, getting those clips out of the valve body was very hard, if I had to do it again I might remove the valve body but my uncle was able to rip the clips out with some good pliers.After that the 99 Tahoe had no problems shifting or climbing mountains or towing. That check engine light never popped again. This probably isn't the best fix but if the trans is old this will help you get more life out of it.

*by J***C on Reviewed in the United States on November 2, 2015*

This valve works real nice.  I really can't see much difference from the existing valve as far as shifting.  I have not yet seen any fault code after 1,000 miles of driving.  It was a little tricky removing and installing the new valve.  Suggest using a bungee and small screwdriver to assist with removing the old valve and clip.  I had to apply pressure on the old valve using a small screwdriver and tap on the clip ends to make it release.  It is important to bend the clip ends in (which took a lot of effort, see YouTube video) to help the lock pin to release.  Also had to use a wood stick to help press the new valve end.  All in all, worked great.
